Two years ago, I wrote a book called “The Sports Gene” that examines the intersection of genetics and athleticism. I expected my mother to buy a dozen copies and invite me to her book club and that would be the end of it. (She did.) Instead, I was almost immediately bombarded with emails from people wanting to know if their kid has Serena Williams’ genes. One coach emailed, wondering how one would get athletes involved in genetic experimentation.
They were coming so quickly, and many were so unhinged, that I took a brief break from opening them.
And then I got one that had this subject heading: “Olympic medalist and muscular dystrophy patient with the same mutation.” Now that caught my attention. I wondered if it might point me to some article or paper in a genetics journal about an elite athlete I’d somehow missed.
Instead, it was a personal note from a 39-year-old Iowa mother named Jill Viles. She was the muscular dystrophy patient, and she had an elaborate theory linking the gene mutation that made her muscles wither to an Olympic sprinter named Priscilla Lopes-Schliep. She offered to send me more info if I was interested. Sure, I told her, send more.
A few days later, I got a package from Jill, and it was… how to put it?… quite a bit more elaborate than I had anticipated. It included a stack of family photos — the originals, not copies; a detailed medical history; scientific papers, and a 19-page, illustrated and bound packet. I flipped through the packet, and at first it seemed a little strange. Not ransom-note strange, but there were hand-drawn diagrams with cutouts of little cartoon weightlifters representing protein molecules. Jill had clearly put a lot of effort into this, so I felt like I had to at least read it. Within a few minutes, I was astounded. This woman knew some serious science. She off-handedly noted that certain hormones, like insulin, were too large to enter our cells directly; she referred to gene mutations by their specific DNA addresses, the way a scientist would.
And then I came to page 14.
There were two photos, side-by-side. One was of Jill, in a royal blue bikini, sitting at the beach. Her torso looks completely normal. But her arms are spindles. They almost couldn’t be skinnier, like the sticks jabbed into a snowman for arms. And her legs are so thin that her knee joint is as wide as her thigh. Those legs can’t possibly hold her, I thought.
The other picture was of Priscilla Lopes-Schliep. Priscilla is one of the best sprinters in Canadian history. At the 2008 Olympics in Beijing, she won the bronze medal in the 100-meter hurdles. It was the first Canadian Olympic medal in track and field since 1996. In 2010, Priscilla was the best 100-meter hurdler in the world.
The photo of her beside Jill is remarkable. Priscilla is in mid-stride. It’s difficult to describe just how muscular she looks. She’s like the vision of a superhero that a third-grader might draw. Oblong muscles are bursting from her thighs. Ropey veins snake along her biceps.
This is the woman Jill thought she shared a mutant gene with? I think I laughed looking at the pictures side-by-side. Somehow, from looking at pictures of Priscilla on the internet, Jill saw something that she recognized in her own, much-smaller body, and decided Priscilla shares her rare gene mutation. And since Priscilla doesn’t have muscular dystrophy, her body must have found some way “to go around it,” as Jill put it, and make enormous muscles.
If she was right, Jill thought, maybe scientists could study both of them and figure out how to help people with muscles like Jill have muscles a little more toward the Priscilla end of the human physique spectrum. Jill was sharing all this with me because she wasn’t sure how best to contact Priscilla, and hoped I would facilitate an introduction.
It seemed absolutely crazy. The idea that an Iowa housewife, equipped with the cutting-edge medical tool known as Google Images, would make a medical discovery about a pro athlete who sees doctors and athletic trainers as part of her job?
I consulted Harvard geneticist Robert C. Green to get his thoughts, in part because he has done important work on how people react to receiving information about their genes. Green was open to discussing it, but he recalls a justifiable concern that had nothing to do with science: “Empowering a relationship between these two women could end badly,” he says. “People go off the deep end when they are relating to celebrities they think they have a connection to.” I was skeptical too. Maybe she was a nutjob.
I had no idea yet that Jill, just by investigating her own family, had learned more about the manifestations of her disease than nearly anyone in the world, and that she could see things that no one else could.
Jill was born in 1974, and she met all the normal baby milestones — sitting, crawling, and walking right on time. She was tiny, though. Not short, just slight. She was so skinny as a three-year-old that she once fell into a toilet bowl, her feet sticking over her head. The stumbling didn’t start until she was four.
Her preschool teacher noticed it first. Pretty soon it morphed into full-fledge faceplanting. Little Jill told her mother she was afraid of witches’ fingers. “When I walked I’d feel the sensation of there were almost little gnarled hands and fingers reaching up and grabbing my shins,” Jill says, “and I’d fall really forcefully.”
Jill’s dad remembered having some trouble walking as a kid, and his doctors told him he’d had a very mild case of polio. But Jill’s symptoms were much more pronounced, and her pediatrician was stumped. He told the family to go to the Mayo Clinic.
They were stumped there, too. They tested the entire family, and saw that Jill, her father and her brother had higher than normal levels of creatine kinase in their blood. That is an enzyme that leaks out of muscles when they are damaged, but Jill was the only one struggling to walk. Based on the creatine kinase, the doctors thought the family might have some form of muscular dystrophy, but that didn’t usually show up this way in little girls, and why did Jill’s father and brother seem fine?
“They were really sure they’d never seen anything like this,” Jill says. “They said our family was extremely unique, and they couldn’t define what type it was. And ultimately, that’s good in one way because they’re being honest. But on the other hand, it was terrifying…It’s alarming if you don’t have something to grasp a hold of.”
Jill returned to the Mayo Clinic every summer, and it was always the same. There was nothing doctors could do, and nothing new they could tell her. The constant falling-on-her-face stopped on its own, but it was replaced by a burning sensation in her legs. And while Jill was growing in height like a normal girl, the fat on her arms and legs was vanishing. By the time she was eight, her arms and legs were so skinny that other kids would wrap their fingers around them and ask if her mother fed her at home.
By 12, veins were starting to pop out of her legs, and the other kids started asking how it felt to be old. She was rail thin, but she could still do most of the things normal kids did. A video of her 12th birthday shows Jill at a pool party, her cannonball displacing a teacup of water.
Later that year, her muscles started to fail again. “I can remember just getting on a bike I’d always ridden,” Jill says, “and feeling like someone came up behind me and just threw me into the handlebars.” Suddenly she couldn’t hold her upper body up over the bike. She invited a friend to go roller skating, and found that she couldn’t stand up on the skates. Over the course of a few weeks, Jill had completely lost the ability to ride a bike and skate.
Something was “terribly wrong,” as she put it, but she didn’t even bother to tell her parents about it. Other people went to doctors and got solutions. That had never happened for Jill, so she started looking for answers on her own, the way a kid would. She started bringing home books from the library on poltergeists and other supernatural phenomena. “I remember it really freaked out my dad at one point,” she says. “He was like, ‘Well, are you into the occult, or what?’ It was nothing of the sort.” It was just that she couldn’t explain the forces acting on her body. She was fascinated by the stories of people bedeviled by inexplicable maladies or situations. Jill says, “Ya’ know, I believe them.”
By the time she left for college, Jill had maxed out at 5-foot-3 and 87 pounds. She had long since moved on from poltergeists, but not from the knowledge that if she was going to figure out what was happening to her body, she would have to go it alone.
Almost as soon as she arrived on campus, she hit the library. She spent more time there than in classes, about 25 hours a week as she recalls it. Twenty-five hours a week just poring over every textbook and scientific journal she could find on muscle disease. She did this for months, going article by article, like a police officer driving up and down every street doing a grid search. But nothing quite fit. Not until she came to a paper in the journal Muscle and Nerve, on a rare type of muscular dystrophy called Emery-Dreifuss. “Looking at the pictures,” Jill says, “it was a very startling thing to realize I’m seeing my dad’s arm.”
Jill’s dad was thin, but the muscles in his forearm and hand were unusually well-defined. Jill would call it a “Popeye arm” when she was a little girl. In another paper she saw that Emery-Dreifuss patients often had that same trait; it was even referred to as a Popeye arm deformity. But she didn’t see pictures of women with the disease.
The Muscle and Nerve paper described the three hallmarks of Emery-Dreifuss patients: They couldn’t touch their chins to their chests, or their heels to the floor, and their arms were perpetually bent at the elbow. The medical term is “contractures.” In middle school, Jill’s head once got stuck for a while so that she was looking up.
“I’m getting chills reading this,” Jill says, “I’ve got all three.” Picture a Barbie doll — arms always bent, feet slanted to fit into high heels, and a stiff neck. It’s “very ironic that we give this to little girls and say this is perfect, and we’re actually handing them a doll that has a genetic disorder.”
Jill was positive that this is what she had. So she read on, and got scared. The papers noted that Emery-Dreifuss always comes with heart trouble. She had to read more, so before going home for college break she stuffed her bag full of medical books and papers.
She didn’t want to scare anyone in the family, so she didn’t read the papers openly. But one day during break, she went to the kitchen to microwave popcorn and returned to find her father perusing the stack of material from her bag. He told her he had all the symptoms she was reading about. “Well, yeah, I know…the arm, and the neck,” Jill told him. No, he replied, all the cardiac symptoms.
Doctors had told Jill’s father years earlier that his irregular heart rhythms had been due to some kind of virus. “It’s not,” Jill told him. “We have Emery-Dreifuss.” She went to the Iowa Heart Center with her Emery-Dreifuss papers and started insisting that a cardiologist needed to see her father. At first, nurses told her she’d need a referral. But Jill had trouble getting one and was so relentless that eventually they gave in. The cardiologist put a Holter monitor on Jill’s dad, which tracked his heart’s electrical activity for a day. At one point, his pulse rate dropped into the 20s, which meant he was either about to win the Tour de France, or he might be about to drop dead. He was 45, and had a pacemaker put in immediately.
“She saved her dad’s life,” Jill’s mother Mary says. “If it wasn’t for her, how would we have ever known this?…But I think it was a hard burden for her because it seemed like no one else was looking.”
Even after the pacemaker surgery, the Iowa Heart Center couldn’t confirm that Emery-Dreifuss ran in Jill’s family. She had, though, in her reading, come across a group of researchers in Italy who were looking for families with Emery-Dreifuss to study, hoping to locate a gene mutation that causes the disease.
So 19-year-old Jill put on her most serious navy pantsuit, again gathered up her papers, and took them to a neurologist in Des Moines. She asked the neurologist to take a look, hoping that she would help her connect with the Italian team and get in the study. But the neurologist would have none of it. “No, you don’t have that,” Jill recalls the neurologist saying sternly. And then she refused even to look at the papers. It might seem rude that a doctor refused just to hear Jill out and glance at the papers, but, at the time, most doctors believed Emery-Dreifuss only occurred in men. Plus, this was a self-diagnosis of an obscure disease coming from a teenager.
So Jill wrote to the Italians herself. She constructed a family tree, noting all the symptoms she saw in her father, two younger brothers and a younger sister, and then she stripped down to her underwear. “I set the timer on my camera and I took pictures of myself,” Jill says, “because I thought, well, if that’s how I identified it, let me send a picture.”
Up to that point, the Italians had only collected four other families to study, so they were thrilled to hear from Jill, and immediately wrote back. From the letter, it seems as though the Italian team thought Jill had access to a lab. Can you send DNA from your entire family? it reads. “If you cannot prepare DNA, just send fresh blood.” And then it gave mailing instructions.
Discouraged by her encounter with the neurologist, Jill figured it would be a dead end to show up at a hospital and ask that her blood be drawn so she could ship it to Italy. So she convinced a nurse friend to smuggle needles and test tubes to her house. They filled them with her family’s blood. At the post office, when Jill declared that her packages contained blood, an employee had to retrieve a big binder that listed what can be shipped to various countries. Fortunately, Italy took blood in the mail.
Today, an entire human genome can be sequenced in a few days. But in the mid-1990s sequencing was a ponderous ordeal. It would be four years before Jill heard back from the Italians.
In the years after she sent her family’s blood overseas, Jill waited for confirmation that she had Emery-Dreifuss. Sort of.
She was so confident that in her annual trips to the Mayo Clinic, she started taking a pen from her purse and writing “Emery-Dreifuss” on her medical chart. Her mom would get upset: “You cannot change your chart!” I want what I actually have to be listed, Jill would tell her.
Then in 1999, Jill got an email from Italy. She stopped before opening it to let the moment sink in. And then she clicked. She had a mutation on a gene known as LMNA, or, for ease: the lamin gene. So did her father, two brothers, and a sister. So did the other four families in the study with Emery-Dreifuss.
Jill had been right about her self-diagnosis, and the researchers discovered the responsible gene mutation. What makes the lamin gene so important is that it carries a recipe for constructing the nuclear lamina, a tangled net of proteins at the center of every cell — one that influences how other genes are flipped on or off, like light switches, changing how the body builds fat and muscle. Mutations in the lamin gene are known to cause more than a dozen diseases, from a gradual loss of physical sensation, to a hyper-rapid aging known colloquially as “Benjamin Button disease.”
Jill’s lamin gene has a typo in it, a serious one. We all have little genome typos, or mutations, hundreds of them. “Mutation” is simply the term for a version of a gene that fewer than 2 percent of the population has. But most of them don’t do anything. Along the spiraling ladders of her DNA, the 3 billion G’s, T’s, A’s and C’s in Jill’s genome, the single-letter typo on her lamin gene just happened to be in a very unfortunate place. To appreciate the scale of what happened to Jill, imagine enough letters to fill 13 complete sets of Encyclopaedia Britannica with a single-letter typo that changes the meaning of a crucial entry.
Jill was glad that she had been right about Emery-Dreifuss, and that she knew her mutation. But, still, “it’s almost darkly comical,” Jill says. “It comes down to a G that was changed to a C.”
Soon after she got her genetic results from Italy, the research group published a paper in the journal Nature Genetics showing that a mutation on the lamin gene can cause Emery-Dreifuss. They thanked Jill at the bottom of the paper. (Her last name at the time was Dopf.)
Jill was 25, and a lab director at Johns Hopkins University had heard through the medical grapevine about the young woman who diagnosed her own Emery-Dreifuss. Wanting both a dogged intern and — why not? — a real-life lamin mutant in her lab, the scientist offered Jill a summer internship. Jill’s job was to sift through scientific journals and find any references to diseases that might be caused by a lamin mutation.
Sitting there day after day, reading, as she had freshman year in college in the library, Jill came across an incredibly rare disease. A disorder called partial lipodystrophy. It caused fat on certain parts of the body, particularly the limbs, to disappear, leaving veins and muscles to stand out, as if they’d been shrink-wrapped in skin. Looking at photos of patients with partial lipodystrophy, all Jill could think was that they looked like her family members.
Could Jill have not just one, but two incredibly rare genetic diseases? The odds of having Jill’s Emery-Dreifuss were so rare that the prevalence isn’t even known; certainly more rare than one in a million. The odds of having partial lipodystrophy are probably somewhere between one in one million and one in 15 million. The odds of separately getting both by chance alone? It was one in far more than the number of people who have lived on Earth, ever.
Jill attended a medical conference at Hopkins during her internship, and, as she had with Emery-Dreifuss, she showed photos to doctors and told them she thought she had partial lipodystrophy. Just like before, they assured her it wasn’t the case. They jokingly diagnosed her with something a lot more common: intern syndrome. “Where you have a medical student being introduced to a lot of new diseases,” Jill says, “and they keep thinking they have what they’re reading about.”
This time, Jill believed the experts, so she dropped it. One rare disease was enough. She went back to reading about Emery-Dreifuss. But pretty soon she dropped that too. She was learning more about all the cardiac problems — the average lifespan of subjects in case studies she read was around 40 — and the stress landed her in the hospital. “I had two panic attacks that were brought on by the stress of reading all these things,” Jill says. “And I went to a counselor for a while and worked with my cardiologist. And we decided it was just too much information. It wasn’t healthy.”
So she stopped reading scientific literature. Cold turkey. No more medical research. No more DIY diagnosis. She started working as a writing instructor at community colleges, and taught adult education at night.
She started dating, and met Jeremy, the man she would marry. And though there was a 50-50 chance she would pass down her Emery-Dreifuss gene mutation, they decided to have a child. Jill’s pregnancy was normal, and her son Martin did not inherit the mutation. But after he was born, Jill’s physical problems accelerated.
She started having muscle twitches — not just little ones, in one muscle at a time, but from head to toe, for hours. Suddenly, she was having to hold on to Jeremy to steady herself when she walked. “The best way I can describe it,” Jill says, “would be like where gravity is getting incredibly heavy.”
By Martin’s first birthday, she could hardly walk. One day, he was calling that he wanted mac and cheese. It was just a few feet to the kitchen. “I had six steps to take,” Jill says, “and I realized this is it. This is the last six steps I’m going to take.” After that, Jill could not get up again.
Her father was losing his ability to walk at exactly the same time, so father and daughter transitioned to life in motorized scooters. Jill remembers seeing her father discouraged for the first time in his life. After one visit with a neurologist, he told her, “I feel like I go there just to be weighed.”
Five years later, Jill’s father told Jill’s mother that he was tired, so he moved from his scooter to his favorite chair. He bowed his head, as if taking a nap, but he never woke up. His heart had finally failed at the age of 63.
On the day her dad passed away, Jill and her siblings and a few relatives had dinner together at her mom’s house. Once most people had left, Jill’s younger sister Betsy pulled Jill over to the computer to show her a picture.
People often asked Betsy what kind of workout she did, because the muscles in her arms were so well defined. But it wasn’t from the gym. Betsy’s arms had always been defined, and as she grew up, she wanted to know why. Jill told her she might want to look into lipodystrophy, but that doctors had told her years ago that she didn’t have it. Betsy attended a meeting for people with lipodystrophy, and there learned about an Olympic sprinter who was conspicuously missing fat. The picture Betsy showed Jill was, of course, Priscilla Lopes-Schliep.
“She pulls up pictures of this extremely muscular athlete,” Jill says. “And I just took one look at it, and just…what?! We don’t have that. What are you talking about?”
But a week later, with the funeral out of the way, Jill got curious. She started Googling. Not just pictures of Priscilla running, but photos of her at home, just hanging around, or feeding her baby daughter. She saw the same prominent veins, the same fall of clothing over shoulders and arms missing fat. The same visible divisions between muscles in the hips and butt. “It was just unmistakable,” Jill says. “It’s like a computer that can analyze a photo and get a match and be 100 percent sure that’s the same shoulder, that’s the same upper arm. I see the same veins, I see them branching this way. You just know and it’s hard to convey, how could you just know. But I knew we were cut from the same cloth. A very rare cloth.”
It was the third time Jill had made a visual lock on something rare. First, it was with her family’s Emery-Dreifuss, then when she thought they had lipodystrophy, and now she thought that she and Priscilla just must have a mutant gene in common because of the exact same pattern of missing fat. But how, then, did Priscilla get a double-helping of muscle while Jill’s muscles were scarcely there?
“This is my kryptonite, but this is her rocket fuel,” Jill says. “We’re like comic book superheros that are just as divergent as can be. I mean, her body has found a way around it somehow.”
If this sounds familiar, it might be because it’s basically the plot of the Bruce Willis and Samuel L. Jackson movie “Unbreakable,” about comic book superheros. Jackson plays a broken-boned, physically fragile man, searching for his genetic opposite, a man born so strong he can survive any physical trauma. In the final scene, Jackson tells Willis he’s the guy.
Jill’s 12-year abstinence from medical literature was over; she wanted to enlist Priscilla in her genetic detective work. Partly out of curiosity, but also because if Priscilla’s body had indeed found some way to “go around” a lamin mutation that should cause muscle failure, it could be important for scientific research.
There was just one practical problem. Jill had no idea how to go about reaching Priscilla so that she could tell her all this. “I’ve had crazy ideas like, can I show up to Canada at a meet and greet or a track event?” Jill says. “You’re just going to get a restraining order at best. I mean, people will think you’re crazy if you’re on this motorized scooter and you’re going up to this hurdler. Nobody in security is going to let you by.”
A full year passed. That’s when I came in.
Jill happened to be in earshot of her television when I started yammering about athletes and genetics on Good Morning America.
“I thought, oh, this is divine providence. This is exactly what I’m looking for,” Jill says. So she sent me an e-mail, and then the package, with original family photos, scientific papers, and the 19-page-bound packet explaining her gene mutation and her theory that Priscilla also had a lamin mutation. Jill wanted my help getting in touch with Priscilla.
It just so happened that Priscilla’s agent and I followed one another on Twitter. So I sent him a direct message. I didn’t expect anything to come of it. I mean, I was telling a pro athlete that a stranger in Iowa wanted to talk to her about getting a genetic test. Luckily, Kris Mychasiw, Priscilla’s agent, is an extraordinarily nice guy. And he also knew that Priscilla constantly faced steroid whispers because of her musculature. After she won the Olympic bronze in 2008, some media in Europe began to openly accuse her. She ran at one meet in France specifically so that she could address the French media.
Kris passed on my request to Priscilla. “He was just like, ‘This lady in Iowa. She says she has the same gene as you, and wants to have a conversation,’” Priscilla recalls. “I was kind of like, “Um, I don’t know Kris.’” But he told her just to have the conversation, and see where it goes.
I talked to Priscilla first, and then she and Jill talked on the phone. Jill sent Priscilla the same 19-page packet she’d sent me. And it wasn’t any of the abstruse science that caught Priscilla, it was the childhood stories Jill shared about kids pointing at the veins in her legs. As a little girl, Priscilla would come home asking her parents to get the veins removed from her legs because the boys were making fun of her. One of Priscilla’s cousins had looked into lipodystrophy, but nobody in the family had ever gotten a firm diagnosis, nor did they know much about the condition. They just knew there were a lot of strong and well-defined people in the family, especially the women. But there wasn’t much impetus to do a deep investigation. After all, when Priscilla was a kid she wasn’t falling like Jill, she was getting strong, and fast. She earned a track scholarship to Nebraska, where she became one of the best athletes in the university’s history and won a national championship. After college she turned professional, and won her Olympic medal.
Still, when Priscilla would walk around at track meets, she’d hear people commenting, she says, “Oh look at her glutes, look at her arms, shoulders, calves. Oh look, look, look!” A picture of a male bodybuilder’s face was pasted onto a photo of Priscilla’s body — while she was straining to the finish line, attempting to make the Olympic final — and posted online. “That was pretty messed up,” Priscilla says. “I was really pissed off about that…A lot of people honestly believed I was taking steroids.”
Priscilla thinks that because of her physique, she was targeted for more than the normal amount of drug testing. (Targeted testing is a standard part of anti-doping.) She was tested right after having her daughter, Natalia. At the World Championships in Berlin in 2009, she was tested just minutes before winning a silver medal. There’s not even supposed to be any drug testing that close to the race.
The following month, at a meet in Greece, someone stole her training journal out of her bag. It was at the very bottom, underneath expensive workout clothes and shoes, none of which were taken. Why steal a training journal? We’ll never know. But I’ve covered a lot of doping stories, and I’m convinced someone thought the journal contained her steroid regimen.
Jill and Priscilla spoke on the phone several times. Then, eight months after I introduced them, they agreed to meet in person. They picked a hotel lobby in Toronto, where Priscilla lived. Jill arrived first, with her mom.
She watched the clock. It ticked past the time they were supposed to meet. Jill got scared. This was a crazy thing she was doing. What if Priscilla had decided not to show? She watched the door. And when Priscilla walked in, Jill’s first thought was “Oh my gosh, it’s like seeing family.”
Priscilla felt the same way. “It really was just a wow moment,” Priscilla says. “Like, do I know you?” The two women started flexing for one another. Priscilla’s muscles many times larger, but with the same definition exposed by a lack of fat. They even retreated to a hallway in the hotel to compare body parts. “There is something real here,” Priscilla recalls thinking. “Let’s research. Let’s find out. Because how could the gene do this to you and this to me? That was what my question was. How?”
Jill offered Priscilla a cashier’s check, money that had been raised for research in a memorial fund after her father’s death. Jill hoped Priscilla would take it and use it to pay for a genetic test. And Priscilla agreed.
It took a year to find a doctor to test Priscilla. She visited several clinics. Some told her they just didn’t do that test. Others said they weren’t sure how to interpret the results, so they felt it wouldn’t be responsible to do the test.
Finally, Jill went to a medical conference and approached the foremost expert in lipodystrophy, Dr. Abhimanyu Garg, who runs a lab at the University of Texas Southwestern Medical Center. He agreed to do both genetic testing and a lipodystrophy evaluation.
The results showed that Jill had been right. She and Priscilla do have a genetic connection. Not only do she and Priscilla both have lipodystrophy — the disease Jill had been told to cast aside back when she was an intern at Johns Hopkins — but they have the exact same subcategory of partial lipodystrophy, known as Dunnigan-type.
And Priscilla did indeed have a mutation on her lamin gene. Both women have a typo on the same one of their 23,000 genes. Priscilla’s is not the exact same “single-letter” typo that Jill has, though; it’s a neighbor typo. That splinter of distance in typo location seems to makes the difference. It’s why Jill has Emery-Dreifuss and Priscilla has fantastic musculature. (That said, there are people with Priscilla’s exact genetic typo who have both fat and muscle wasting.)
Dr. Garg called Priscilla immediately to give her the news. He caught her at the mall, shopping with her kids. “I was just dreaming about going out and getting a juicy burger and fries,” Priscilla says, “and Dr. Garg calls me and says, ‘I have your results.’” Priscilla asked if she could call him back later, after lunch. He said that she could not. “He’s like, ‘You’re only allowed to have salad. You’re on track for a [pancreatitis] attack.’ I was like, ‘Say what?’”
Despite her monstrous training regimen, Garg informed Priscilla that, due to her unmonitored lipodystrophy, she had three times the normal level of triglycerides, or fat in her blood. Garg has had a number of partial-lipodystrophy patients with unusually large muscles who were good athletes, but none as muscular nor as athletically accomplished as Priscilla. He thought her training would probably protect her from the buildup of fat in her blood, but he was wrong. “I thought with her physical training, I’m not going to find much metabolic abnormalities,” Garg says. “But this was the one thing that was a severe problem on her blood testing.”
In other words, Jill had once again helped steer someone away from a medical disaster. She had prolonged her dad’s life, and now — once again with that cutting-edge medical tool Google Images — she caused the most intense medical intervention that a professional athlete had ever had. Priscilla called Jill to tell her. “I was like, ‘You pretty much just saved me from having to go to the hospital!’” Priscilla says. “Dr. Garg told me I have the gene and my numbers are out of the roof.”
Even Garg was startled by what Jill had done. “I can understand a patient can learn more about their disease,” he says. “But to reach out to someone else, and figure out their problem also. It is a remarkable feat there.”
Priscilla has now overhauled her diet and started medication. She was recently recruited to try bobsled for Canada, which — if all goes well — could give her a chance to be the sixth athlete ever to win a medal in both the Summer and Winter Olympics. And, with her genetic test, she hopes the steroid whispers will die down too.
A little more than a decade ago, when the first full human genome was sequenced, some medical futurists and optimistic doctors prophesied that we’d all bring our genetic information to the doctor’s office to get treatment personalized to our DNA. Not only has that not materialized, but, for the most part, studies that scan entire genomes for disease-causing DNA “have not resulted in anything clinically useful,” says Heidi Rehm, a geneticist at the Harvard Medical School.
It’s not that there aren’t plenty of genes that matter, but it turns out that unraveling genetic causes of disease is a whole lot more complicated than that wishful thinking of a decade ago. Rather than single genes causing a disease — or any trait, really — it’s usually many small genes, each with a tiny effect, combining to influence a condition, and doing so in concert with lifestyle and other environmental factors.
Many rare diseases, though, actually are caused by single genes that alone have a large impact on biology. So those mutant genes have been far easier to locate. And sometimes when scientists can figure out what’s causing a serious and rare disease, they can begin to untangle more common ailments. “As you begin to understand these pathways,” Rehm says, “there will be milder versions of those rare diseases you can help to affect by understanding the outliers.”
For example, research on a rare gene mutation, which gave people such low cholesterol levels it was a wonder they were alive, led to a treatment for high cholesterol. An Alzheimer’s treatment may one day come from ongoing research on a small group of people in Iceland who have a version of a gene that protects their brains in old age.
Recently, Rehm and a group of scientists started something called the Matchmaker Exchange, it’s a kind of OkCupid for rare diseases, where people with uncommon conditions can be matched with other people with similar diseases and gene mutations, in the hope that it will spark new discoveries. After all, under normal circumstances, Jill and Priscilla never would have ended up in the same doctor’s office. A person with a rare disease in their family will often have seen more cases and different manifestations of the disease than any doctor has.
Rehm herself discovered that Norrie disease, which causes loss of sight and hearing, is not only a neurological, but also a blood-vessel disease when she found a Yahoo message board where Norrie patients were all discussing their erectile dysfunction. “I think there is a cultural change,” she says. “Physicians are recognizing the very important role of the patient in being not only an advocate for themselves, but really a source of relevant information.”
Dr. Garg, who has studied lipodystrophy for 30 years, says that Jill and Priscilla are the most extreme cases of muscle development he has ever seen in lipodystrophy patients — on opposite ends of the spectrum, of course. What might be causing that?
Jill and Priscilla don’t have the exact same typo, or “point mutation.” Because of that, they have one condition precisely in common — Dunnigan-type partial lipodystrophy — and another that is divergent as can be — their muscles. But the mechanism behind their difference is an important mystery. It might not surprise you by now that, in search of an answer, Jill hit the scientific journals.
She alighted on the work of a French molecular biologist named Etienne Lefai. He does extremely technical work on a protein with the less than mellifluous name: SREBP1. SREBP1 has long been known to manage fat storage. After a meal, SREBP1 is helping each of your cells decide whether to use the fat that just arrived for fuel or store it for later.
Lefai’s team found, in animals, that a buildup of SREBP1 in the cell can lead either to extreme muscle atrophy or extreme muscle growth. And that was something Jill was interested in. She sent Lefai a two-line email with a question about his work. He thought it was from a scientist or Ph.D. student and responded.
Soon, Jill told Lefai about her own history, and suggested that it is possible that he discovered the actual biological mechanism that makes her and Priscilla so different — SREBP1 interacting with lamin.
“Okay, that triggers a kind of reflection from my side saying ‘That’s a really good question. That’s a really, really good question!’” Lefai says, in a thick French accent. “Because I had no idea of what I can do with genetic diseases before she contacted me. Now I have changed the path of my team.”
Since Jill first contacted him, he has learned that lamin proteins — which the body creates using instructions from the lamin gene — can interact with SREBP1. Now Lefai is working to figure out whether a lamin gene mutation alters the ability of lamin proteins to regulate how SREBP1 works, causing simultaneous loss of muscle and fat. It’s possible, though certainly not assured, that his work could ultimately lead to new treatments.
Given how technical his work is, I asked Lefai if he had ever had someone from outside the science community influence his research. “In my life, no,” he says. “People from outside coming and giving me hope? New ideas? I have no other example of this kind of thing. You know, maybe happen once in a scientific life.”
It is the dream of many rare disease patients to have a scientist orient his research agenda around them.
The first time Jill and I spoke, she told me that she knew there would be no treatment breakthrough in her lifetime. (Although, I’m not so sure.) But she doesn’t want what she learned to be lost, and hopes that maybe she’ll have made a small contribution to some therapy that’s developed for some other generation. She told me recently that she has proved her point, and she’s thrilled that she was able to help Priscilla improve her own health.
The two women have stayed in touch. They talk about their kids. Priscilla is quite sure her daughters got her mutation. She can feel the difference between other kids and her own when she lifts them. Her girls are dense, with solid muscles.
In my years of reporting on genetics and athleticism, I only know of two other cases where rare versions of single genes were associated with elite athletic performance, and the other two debuted in medical journals.
Still, Jill told me that she’s officially retiring, for good this time, from DIY diagnosis. She gave me the same line that athletes so often wield when they hang ‘em up: I want to spend more time with my family.
Her mother, Mary, says it would be great if Jill could move on and just focus on the rest of her life. But do you think she’ll really retire? I asked. “Probably not,” Mary told me.
Lefai laughed when I asked if he thought Jill would quit. “Of course she will continue,” he says. “I don’t believe that retirement. In the last email, she told me she was in contact with people in New Zealand.”
It’s been two-and-a-half years since Jill happened to hear me on television and decided to reach out. Before Priscilla agreed to get a genetic test, I hadn’t really thought of all this as a story I would one day write. I just thought Jill deserved a response. But I don’t believe she’s retiring either.
Recently, Jill sent me an email. She’d picked up on a tidbit in a very technical scientific paper about potentially reversing muscular dystrophy. “I don’t want to read too much into this,” she wrote me. “But of course, I’m curious.”
