CDKN2A and type 2 diabetes mellitus: Further analytic results from ULR consistently support the existence of potential additive gene-environment interactions between CDKN2A/B (rs10757274) and T2DM, with a combined effect of increasing the risk of MI for T2DM-positive subjects with genotype GG/GA by 4.38 times that of T2DM-negative subjects carrying genotype AA.
