Haplotype blocks among all of the analyzed IL10RA polymorphisms were observed when all subjects of the study were included (n = 202), while in the SLE patients, haplotype blocks were observed between rs10892202 and rs4252270 (D’ = 1, r2 = 1) and between rs2229113 and rs9610 polymorphisms (D’ = 0.98, r2 = 0.42). Here, IL10RA is linked to systemic lupus erythematosus.
