PG - 356-62 LID - 10.1111/j.1399-0039.2012.01931.x [doi] AB - Microsatellite polymorphism in exon 5 of major histocompatibility complex class I chain related gene-A (MIC-A) has been implicated in the etiology of autoimmune diseases including type 1 diabetes (T1D) and celiac disease (CD). In this study on North Indian population, the MIC-A5.1 allele, carrying a premature termination codon in transmembrane region, was observed with increased frequency in T1D (29.6%, odds ratio OR = 2.1, P = 0.00017) and CD patients (40.3%, OR = 3.37, P = 1.67E-05) than in controls (16.7%). When the MIC-A5.1 association was adjusted for linkage with human leukocyte antigen (HLA)-DR3, the statistical significance of the association was abolished. This implies that the observed association of MIC-A5.1 is due to its linkage disequilibrium (D' = 0.94) with HLA-B8-DR3-DQ2 haplotype and is secondary to the overall association with DR3 positive MHC haplotypes.
