A study on association of SNP-43 polymorphism in Calpain-10 gene with type 2 diabetes mellitus in the population of Eastern Azerbaijan province

Background: Genome - wide analysis of genetic predisposition to type 2 diabetes mellitus in different populations have yielded variable results. Calpain10, a gene that encodes a non-lysosomal cysteine protease, has been recently proposed as a type 2 diabetes susceptibility genes in the non-insulin-dependent diabetes mellitus NIDDM1 region. Aim of the study is to evaluate the relation between SNP43 and type2 diabetes. Methods: A total of 102 diabetic subjects and 100 undiabetic controls enrolled in a case-control study in Eastern Azerbaijan Azerbaijan Province. The polymerase chain reaction restriction fragment length polymorphism technique (PCR-RFLP) was applied. We use X2 test and logistic regression to analysis of data. Results: Genotypes distribution of calpain10 gene in control group were 11(11%), 86(86%) and 3(3%) with respected to A/G, G/G and A/A genotypes, respectively. In diabetic group genotypes distribution were 7(6.9%), 95(93.1%) and zero, respectively. The G allele frequency was significant difference in case and control groups. Conclusion: Since G allele is a risk factor to affect type 2 diabetes disease hence SNP43 of calpain10 gene had significant association with type 2 diabetes in Eastern Azerbaijan.
