In this study, we examined the associations of sixteen single nucleotide polymorphisms (SNPs) from nine genes (KCNJ1 (rs675388, rs59172778, rs12795437, and rs11600347), CACNA1C (rs2239128, rs2238032, and rs1051375), WNK1 (rs880054), NPPA (rs5065), STK39 (rs6749447), LUC7L2 (rs6947309), NEDD4L (rs75982813 and rs292449), NPHS1 (rs3814995), and BDKRB2 (rs1799722 and rs8012552)) with the risk of hypertension in the Jordanian population. The gene discussed is CACNA1C; the disease is hypertensive disorder.
