Research Abstract

Disposition index determined by glucose clamp technique (clamp DI) differed significantly among NGT, IGT and T2DM. Clamp DI was decreased with deterioration in glucose tolerance. Therefore, we consider clamp DI as more sensitive measure of beta cell function. We showed the risk allele of KCNQ1, which is the most important disease susceptibility gene identified by Japanese people, was associated with decrease of clamp DI in IGT.
