An association of STAT4 (rs10181656) with PsA was confirmed whereas CD226 (rs763361) was associated with PsA but not with RA, in contrast to previous reports.
Recently, there has been increasing evidence shown that a non-synonymous exchange (Gly307Ser/rs763361) of the CD226 gene on chromosome 18q22 is linked to several autoimmune diseases (ADs) including type 1 diabetes (T1D), celiac disease (CED), rheumatoid arthritis (RA), multiple sclerosis (MS), Grave's disease, Wegener's granulomatosis (WG), psoriasis, and primary sicca syndrome (pSS).
Disease-specific meta-analysis showed an association between systemic lupus erythematosus (SLE) and the CD226 rs763361 T allele (OR 1.150, 95% CI 1.040-1.271, p = 0.006), but no association between rheumatoid arthritis and the CD226 rs763361 polymorphism (OR for the T allele 1.207, 95% CI 0.913-1.596, p = 0.187).
We replicated the genetic association with rs13277113 (p = 0.0009, OR 1.46) and rs2736340 (p = 0.0001, OR 1.63) from C8orf13-BLK (8p23.1, associated with RA and systemic lupus erythematosus), and rs763361 (p = 0.03) from CD226 (18q22.3, associated with multiple sclerosis and type 1 diabetes) in the Colombian population.
Recently, there has been increasing evidence that a non-synonymous exchange (Gly307Ser) in the gene for CD226 is linked to several autoimmune diseases including type 1 diabetes, multiple sclerosis (MS), rheumatoid arthritis and Grave's disease.
In addition to the analysis of newly available samples in T1D (2088 cases and 3289 controls) and autoimmune thyroid disease (AITD) (821 cases and 1920 controls), resulting in strong support for the Ser(307) association with T1D (P=3.46 x 10(-9)) and continued potential evidence for AITD (P=0.0345), we provide evidence for association of Gly307Ser with MS (P=4.20 x 10(-4)) and rheumatoid arthritis (RA) (P=0.017).
