Abstract
Background. In several large studies an association between certain single-nucleotide polymorphisms (SNP) of the calpain-10 gene (CAPN10) with type 2 diabetes mellitus (T2D) has been identified. Since T2D and gestational diabetes mellitus (GDM) seem to be linked pathophysiologically, we examined the frequencies of CAPN10-polymorphisms in women with GDM. Methods. By using real-time PCR assisted melting curve analysis samples of 204 women with GDM and 297 controls were tested for variations of SNP-43, -44, -63 and Indel-19 of CAPN10. Results. Since the genotype frequencies found in SNP-44 among the controls did not meet the Hardy-Weinberg-Equilibrium, the further analysis was performed with SNP-43, -63 and Indel-19 only. Herein, the distribution of neither genotype nor allele nor haplogenotype-combination nor haplotype showed a significant difference between both groups. Conclusions. Variations of SNP-43, -63 and Indel-19 of CAPN10 were not associated with an increased risk of developing GDM.
