HEDGE Study, Ehlers-Danlos Syndrome

 
Early this morning, I had my blood drawn. And aside from the fact that I’m a difficult stick because my veins collapse, this shouldn’t be something to write a blog post over. But this is a big deal.

 I was invited by the Ehlers-Danlos Society to participate in the HEDGE study. Its goal is to find the genetic markers for the type of Ehlers-Danlos Syndrome I have. They will do a whole-genome sequencing study of 1,000 people from 86 different countries who have hEDS.

I’m very thankful to everyone who has donated time, money, and blood to run this study. (It’s hard to find research money for rare diseases.) My hope is this study will make diagnosis quicker and easier and raise awareness in the medical community, so that no one else will have to wait 50+ years for a diagnosis. Go, zebras!

What’s up with EDS?

1.       It’s a rare genetic connective tissue disorder named after two dermatologists who each wrote about patient who had skin that was hyperextensible—super stretchy.

2.       It’s a collagen disorder. Since collagen is in almost every organ, tissue, and system, they can all be affected. That means the pain is chronic, often excruciating, and exhausting. (And no, taking collagen doesn’t solve the problem because our bodies take the collagen from what we eat and drink to build the collagen we need, but EDS bodies build it incorrectly.)

3.       It’s genetic, but not all affected family members share exactly the same symptoms (though they will have the same subtype). It’s also much more commonly diagnosed in women—hormones may affect gene expression.

4.       There are 13 subtypes, each with its own problems and prognosis.

5.       Getting diagnosed. Studies show that it takes the average EDS patient 19 years (yes, 19 years!) to go from showing symptoms to diagnosis. It took 37 years for me to go from symptoms to diagnosis. Partly, it’s because EDS is so rare most doctors haven’t seen a patient with EDS. The 2017 estimate is that somewhere between 1 in 5,000 to 7 in 1,000 people have the type of EDS that I have.

6.       Why is a zebra the mascot for EDS? Doctors are taught when you hear hoofbeats think horse not zebra. After all, it’s pretty rare to find a zebra. But they exist—and so do people with EDS, even though we’re few a far between. 😊

February 29 was Rare Disease Day. I’m a few days late, but here’s my rare disease story: Ehlers-Danlos Syndrome (incidence 1/10,000 to 1/20,000 for my subtype).

After a lifetime of knowing something wasn’t quite right with my body, a geneticist recently diagnosed me with Ehlers-Danlos Syndrome, a genetic connective tissue disease, which affects all the body’s organs and tissues causing deterioration and degeneration. The subtype I have is characterized by pain and exhaustion. (Honestly, I don’t remember a time I wasn’t fighting pain or exhaustion—I thought it was normal. I told myself, “Suck it up, Buttercup.”) Without going into the nitty-gritty, the geneticist explained my condition this way: Imagine your body is a house built with nails that are soft. It’s not too bad at first. But over time, the nails fail. The shingles and siding blow off. The wallboard falls down, and the floors come apart. And, the 2 X 4s holding the structure together start to separate from each other.  (Not the most encouraging metaphor…)

There is no treatment for EDS. The only thing doctors can do is treat the symptoms. Because my house is in its fifth decade, a lot of things are falling apart (spine, joints, eyes, digestive system, circulatory system, etc.). But I am thankful. After 53 years, it’s nice to know why.
