Differential methylation in blood pressure control genes is associated to essential hypertension in African Brazilian populations.

ABSTRACT: While genetic studies have provided insights into essential hypertension (EH, defined by high blood pressure ≥140/90 mmHg), investigation through epigenetics may address gaps in understanding its heritability. This study focused on African Brazilian populations in Vale do Ribeira River region, due to their high hypertension prevalence. We aimed to determine if DNA methylation is linked to hypertension susceptibility, through a genome-wide evaluation of 80 peripheral blood samples from normotensive (39) and hypertensive (41) individuals, with Infinium Methylation EPIC BeadChip platform. Data were analyzed using ChAMP package and cross-referenced with information from databases such as EWAS Atlas, GWAS catalog, GeneCards, literature, and tools such as VarElect and EWAS Toolkit.
