We aimed to evaluate the effect of four common variants (rs2237892, rs2283228, rs2237895, and rs2237897) in KCNQ1 on susceptibility of type 2 diabetes (T2D) by performing a case-control study as well as a comprehensive meta-analysis.
In conclusion, this meta-analysis suggests that rs2237892, rs2237895, rs2237897, rs2283228, and rs231362 polymorphisms in KCNQ1 are associated with elevated T2D risk.
The haplotype TCA containing the allele of rs2237892 (T), rs2283228 (C) and rs2237895 (A) was highly protective against T2D (Second model; OR = 0.17, P = 3.7 × 10(-11)).
Four single nucleotide polymorphisms (SNPs) (rs2237892, rs2237895, rs2237897, and rs2283228) in KCNQ1 are reported to be associated with type 2 diabetes mellitus (T2DM), possibly caused by a reduction in insulin secretion and higher fasting glucose, but the results are inconsistent.
Four single nucleotide polymorphisms (SNPs, rs2237892, rs2237895, rs2237897, rs2283228) in KCNQ1 are associated with type 2 diabetes mellitus in different ancestral groups.
SNPs rs2237897, rs2237892, and rs2283228 were significantly associated with type 2 diabetes (odds ratio [OR] 1.48, P = 3 x 10(-4); OR 1.38, P = 0.002; OR 1.31, P = 0.012, respectively).
