TCF7L2 and type 2 diabetes mellitus: Asian population studies showed lower IVS3‐T prevalence (5%‐15%) as opposed to Caucasian ones (36%‐46%), and even up to 50% in African populations.10 IVS3‐T allele prevalence (11%) in Kyrgyz population was somewhat similar to other Asian populations.11 Literature data support the role of IVS3‐T allele of TCF7L2 gene IVS3C/T polymorphic locus with T2D in the European populations.10 In Asian populations, TCF7L2 gene IVS3C>T polymorphic locus is either not associated with T2D separately or has a weak association.11, 12, 13
