From the twenty-five most strongly associated SNPs for hypertension, EPHA6 rs4850755 was the most highly associated SNP with both systolic BP (P = 2.63E-08) and diastolic BP (P = 3.67E-05); therefore, we performed an association analysis on rs4857055 in EPHA6 (Additional file 1: Table S1). This evidence concerns the gene EPHA6 and hypertensive disorder.
