I learned several days ago that my mother’s sister has been officially diagnosed with RA. My mother’s side of my genetic tree is an absolute minefield. It’s where I get all of my lung issues and allergies. I would bet if I could get my mother tested, I’d find it is also where I get the HLA-DQ2 I carry which has the highest association of any HLA serotype with autoimmune disease.
I was able to convince both of my parents to go paleo so I won’t demand her blood to prove my suspicions. 🙂
