Some SNPs are linked to the risk of coronary artery disease (CAD), such as genetic variants of the KCNQ1 gene (rs2237892, rs2237895, rs2237897, rs2283228), encoding the potassium voltage-gated channel subfamily Q [7], as well as other CVD phenotypes such as glycemia, inflammation, lipids, and blood pressure [8]. The gene discussed is KCNQ1; the disease is coronary artery disorder.
