Among the 10 genes that were suggested to be related to BP by GWAS, we showed that methylation levels of PRDM6, HDAC9, IGFBP3, SYT7, PDE3A, TBX2 and C17orf82 in blood cells were associated with BP and that methylation levels of PRDM6 and SYT7 were associated with hypertension risk among Chinese individuals. Here, IGFBP3 is linked to hypertensive disorder.
