TL;DR: The data implicate KCNQ1 as a diabetes susceptibility gene in groups of different ancestries as well as in two independent Japanese populations, and the risk allele of this polymorphism was associated with impairment of insulin secretion according to the homeostasis model assessment of β-cell function or the corrected insulin response.
Journal ArticleDOI
Diabetes in Asia.
TL;DR: National strategies to raise public awareness about the disease and to improve standard of care and implementation of programmes for primary prevention are urgently needed to reduce the economic burden due to diabetes at personal, societal, and national levels.
