KCNQ1 and type 2 diabetes mellitus: Given that it is still unknown whether these 4 SNPs in KCNQ1 are associated with plasma lipid parameters besides their inconsistent association with T2DM [1-10], to fill this knowledge gap, we aimed to determine whether these 4 common SNPs at KCNQ1 loci would correlate with plasma lipid parameters in a middle-aged Chinese Han population living in East China.
