Hey! I have some thoughts on the paper below that attempts to position #ME/CFS as an “autoimmune disease” by associating 2 SNPs with very small odds ratios to differences b/t infectious & noninfectious disease onset (OR=0.54 & OR=0.64): frontiersin.org/articles/10.33…
2/ The team didn’t study the #ME/CFS immune response itself, but instead measured several common #SNPs associated w/ certain “autoimmune” conditions in their ME/CFS subjects. For example SNPs in the gene PTPN22 (connected to #Crohn’s, type 1 #diabetes etc)
3/ PTPN22 is a gene that, in simple terms, plays a role in regulating B and T cell activity. It’s actually just a gene that impacts the immune response (there doesn’t HAVE to be anything “autoimmune”-inducing about PTPN22 activity)
