rs5219, also known as E23K, is a SNP in the KCNJ11 gene.

The association between type-1 diabetes and rs5219 is mentioned as being replicated in [PMID 17554300OA-icon.png]; there is also a 90% correlation between rs5219 and rs5215.

This SNP is one of 4 relatively common SNPs reported to represent risk for type-2 diabetes in the DESIR prospective study of 3,877 Caucasian participants. Under an additive model, the odds ratio for the minor (risk) allele (T) is 1.15 (CI: 0.95-1.4, p=0.2, ie not significant). But for the 4 SNPs, each risk allele increased type-2 diabetes risk by 1.34x (p=2x10e-6), with an odds ratio of 2.48 (CI: 1.59-3.86) for carriers of 4 or more compared to those with one or none (risk alleles).[PMID 17977958]

Genotyping of ~4000 Chinese as well a meta-analysis concluded that rs5219 was associated with type-2 diabetes in Chinese Han and East Asian populations, under a recessive model showing an odds ratio of 1.25 (CI: 1.04-1.5, p=0.017).[PMID 19498446]
