Hypertension 3.1 X more likely in males with poor CPY24A1 gene (but 2.5 X less likely for females)

Highlights
Risk of essential hypertension was found to be sex-dependent in the carriers of CC genotype of CYP24A1 rs2762939.
In the CC carriers of CYP24A1 rs2762939, females demonstrated a protective role whereas males had higher risk in the genetic predisposition to EH.
The levels of 25-hydroxy Vitamin D and total renin concentrations may explain this contrasting risk posed by the CYP24A1 rs2762939 CC variant.
CYP24A1, Vitamin D 24-hydroxylase catabolizes 25-hydroxyvitamin D (25(OH)D) and 1,25-dihydroxyvitamin D to 24-hydroxylated vitamin D products. It is widely known that low Vitamin D can lead to increased renal renin and angiotensin II production, consequently elevating blood pressure or development of essential hypertension (EH). We have conducted an investigation on hypertensives and controls to evaluate the association of the gene variant, CYP24A1 rs2762939 and 25(OH)D in an Indian population with EH. On gender-based stratification, with multivariate logistic analysis after adjustment for covariates, the CYP24A1 rs2762939 CC variant showed a higher risk of EH in males (aOR = 3.141 , CI 1.164–8.478, P = .024) while females illustrated an inverse association with EH ( aOR = 0.398 , CI 0.172–0.092, P = .031). The 25(OH)D levels among the three genotypes of hypertensives substantiate these results. Our results clearly suggest that gender, CYP24A1 rs2762939, and Vitamin D status may play a significant role in disease susceptibility towards EH in Indian population.
