There are 4 confirmed cases in my family between 2 generations. One of my siblings refused to be checked even though she sounds symptomatic.Her son has some unrelated issues as well.
They say about 6% of cases are familial. Who knows how many family members just never knew. I have already had both my kids checked, one confirmed after a year fight with the doctors and headache/syncopal episodes, the other not herniated enough to be diagnosed although she does have migraine with aura and slight herniation.
I also have other genetic mutations in my family as well. We know of Factor 5 Leidens ( clotting disorder) and my father has Graves disease And aortic aneurysm as well.
These conditions seen to come in blocks. I also have Raynauds. I have spoke with other Chiarians about this kind of stuff and definitely think there is one source for all these related issues.
Would be wonderful to see more research done in hopes of reducing our eliminating the risk for our kids kids!
