Synergistic effect between the KCNQ1 haplotype and alcohol consumption on the development of type 2 diabetes mellitus in Korean cohorts

Abstract Potassium voltage-gated channel subfamily Q member 1 (KCNQ1) is one of the strongest susceptibility genes for type 2 diabetes mellitus (T2DM). Association studies between KCNQ1 genetic variants and T2DM have been reported. The multifactorial disease T2DM is caused by interactions between ge...

Association studies between KCNQ1 genetic variants and T2DM have been reported. The multifactorial disease T2DM is caused by interactions between genetic susceptibility and environmental factors. In this study, we examined the associations between the KCNQ1 haplotype, which consists of the major alleles rs3852528, rs11024175, and rs2237892 (ht: ACC), and environmental factors such as alcohol consumption, which are related to the risk of T2DM, in two independent Korean populations.

Moderate-to-heavy drinkers with the ACC haplotype had lower fasting insulin levels and mean 60 min insulinogenic index (IGI60) compared with light drinkers and abstainers not carrying the ACC haplotype.
