MAST4 and Hypertension: In this study, a GWAS using TWB data to test the association of SNPs with hypertension reported 6 SNPs (rs1458038 in FGF5, rs3796605 in FGF5, rs455938 in MAST4, rs10866754 in CTC-535M15.2, rs648435 in APHGAP42, and rs2018159 in APHGAP42) to be significantly associated (P < 5e-6) with hypertension (Table 4).
