Rs7923837

From SNPedia

rs7923837 is a SNP of the HHEX homeobox gene. In several studies, it has been associated with risk for type-2 diabetes (T2D).

In a study of 500 unrelated Caucasian T2D patients, the rs7923837(G) allele was overrepresented; the odds ratio was 1.57 (CI: 1.08-2.27, p=0.017). In this population, the population attributable risk for this allele was estimated to be 33%.[PMID 18231124]

In a study of ~400 Japanese T2D patients, rs7923837(G) was also associated with type-2 diabetes (odds ratio 1.66, CI: 1.28-2.15, p=0.00014). Heterozygous and homozygous carriers of the risk allele had odds ratios of 1.57 (95% CI 1.15-2.16, p=0.0050) and 3.16 (95% CI 1.40-7.16, p=0.0038) relative to non-carriers.[PMID 17971426]

[PMID 18477659] rs7923837 replicated as significant for type-2 diabetes risk in 1,900 Japanese patients, with odds ratio of 1.27 (CI: 1.13-1.43, p = 1.0 x 10e-4)

[PMID 19033397] This SNP was confirmed to be associated with type-2 diabetes in a study of 500+ Japanese patients plus pooled meta-analysis with 6 previous association studies (also of Japanese).
