In one study it was reported that a KCNB1 SNP in the 3′ untranslated region (rs1051295) is associated with decreased insulin sensitivity, increased triglyceride and increased waist/hip ratio in the Chinese Han population, which can increase the risk for type 2 diabetes; this was not observed in the individuals in the current study (Zhang et al., 2013). This evidence concerns the gene INS and type 2 diabetes mellitus.
