Abstract

Introduction: The variations in the Calpain-10 gene have been suggested to be related to susceptibility to type 2 diabetes mellitus (T2DM) in different populations. In this study, we investigated the relationship between single nucleotide polymorphism (SNP)-19, -44 and -63 in the Calpain-10 gene and the development of T2DM in a Turkish population.

Material and methods: A total of 211 subjects were recruited: 118 patients with a diagnosis of T2DM and 93 unrelated healthy subjects.

Results: There were no significant differences in the genotype and allele distribution of SNPs studied between the patients with T2DM and controls (p > 0.05), whereas the frequencies of 121 haplotype and 122/121 haplotype combination were found to be higher in patients with T2DM than in controls (p < 0.05). No association was observed between the variations in the Calpain-10 gene and glycaemic control and lipid parameters (p > 0.05). The SNP-19 insertion/insertion was significantly related to increased body mass index (BMI) in male diabetic patients (p < 0.05).

Conclusions: The present study indicates that 121 haplotype and 122/121 haplotype combination of SNP-19, -44 and -63 in the Calpain-10 gene are associated with the development of T2DM in Turkish patients. (Endokrynol Pol 2014; 65 (2): 90–95)
