Rs763361

rs763361, also known as Gly307Ser, is a SNP in the immune response CD226 gene. The rs763361(T) allele (in dbSNP orientation) encodes the Ser.

Based on multiple studies (by one group) now totaling over 2,000 patients, the rs763361(T) allele is associated with increased risk for multiple autoimmune diseases, including type-1 diabetes (p = 3 x 10e-9), multiple sclerosis (p = 4 x 10e-4), and possibly rheumatoid arthritis (p = 0.017). Based on tag SNP analysis, the authors conclude that this SNP could be the causal variant.

Tested in a large multiple sclerosis data set consisting of 2369 trio families, 5737 cases and 10 296 unrelated controls, SNP rs763361 was associated with disease risk (p = 5.4 x 10e-8)
