Frontiers in Genetics, 13, 937639. https://doi.org/10.3389/fgene.2022.9376391664-8021https://doi.org/10.3389/fgene.2022.937639http://hdl.handle.net/10566/7740The current study sought to investigate the association between the methylenetetrahydrofolate reductase (MTHFR) variant (rs1801133) and the risk of developing hypertension (HTN) in an indigenous South African population.A total of 442 participants (hypertensive, n = 279 and nonhypertensive, n = 163) from the indigenous tribe residing in Mthatha, Eastern Cape (South Africa) were recruited. HTN was defined as a systolic (SBP) and diastolic blood pressure (DBP) of ≥130/80 mmHg following American Heart Association guidelines. The genotyping of MTHFR (rs1801133) was assessed using MassARRAY® System. Thereafter, the association between rs1801133 in various genetic models and HTN was determined by logistic regression model analysis. Furthermore, the interaction between rs1801133 and selected risk factors on HTN was performed using the open-source multifactor dimensionality reduction (MDR).enHypertensionGenetic variationBiotechnologyAfricaMental disorderArticle
