title: Co-existence of risk and protective haplotypes of Calpain 10 gene to type 2 diabetes in the eastern Indian population.
abstract: Linkage and association studies have detected a role for Calpain-10 (CAPN10) polymorphisms in susceptibility to T2DM in many populations. This study aimed to evaluate possible associations between three SNPs in the CAPN10 (UCSNPs -43, -19 and -63) gene and T2DM in the east Indian population. The distribution of genotype frequency of UCSNP-63 varied significantly between T2DM patients and controls under a dominant model. The uncommon (T) allele (OR = 3.74, 95% CI: 1.44-9.7) of the UCSNP-63 and haplotype 112 (OR = 3.4, 95% CI: 1.17-9.9) were associated with increased risk of T2DM. On the contrary, the most common haplotype 121 (OR = 0.70 95% CI: 0.50-0.99) was associated with a reduced risk for T2DM. In our population a novel 111/112-haplotype combination created by the CAPN10 UCSNP-43, -19 and -63 was associated with risk of T2DM. Haplotypes 112 and 121 with opposite genetic influences also co-exist in our population.
