GPR19 and myocardial infarction: The two other associated SNPs in the AA group, rs2270451 (P = 0.024) and rs2301523 (P = 0.039), are located in the 2-Kb upstream sequence of GPR19 (G protein-coupled receptor 19) and within the non-protein coding RNA MIAT (myocardial infarction associated transcript), respectively.
