Stratification analysis by diseases suggested FAM167A-BLK rs2736340 had a positive association with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), systemic sclerosis (SSc) and Kawasaki disease, primary Sjogren's syndrome (pSS), primary antiphosholipid syndrome (APS), and myositis.
Our results indicated that the SNPs (rs2736340, rs13277113) of the FAM167A-BLK region, but not the BANK1 SNPs (rs4522865, rs17266594, and rs10516487), were associated with the development of pSS in Han Chinese.
