Abstract

OBJECTIVES: 25-Hydroxyvitamin D (25(OH)D) deficiency and excess activity of the renin-angiotensin system (RAS) are both associated with cardiovascular disease. Vitamin D interacts with the vitamin D receptor (VDR) to negatively regulate renin expression in mice; however, human studies linking genetic variation in the VDR with renin are lacking. We evaluated (i) whether genetic variation in the VDR at the Fok1 polymorphism was associated with plasma renin activity (PRA) in a population of hypertensives and a separate population of normotensives and (ii) whether the association between Fok1 genotype and PRA was independent of 25(OH)D levels. DESIGN/PATIENTS/MEASUREMENTS: Genetic association study, assuming an additive model of inheritance, of 375 hypertensive and 146 normotensive individuals from the HyperPATH cohort, who had PRA assessments after 1 week of high dietary sodium balance (HS) and l week of low dietary sodium balance (LS). RESULTS: The minor allele (T) at the Fok1 polymorphism was significantly associated with lower PRA in hypertensives (LS: β = -0·22, P < 0·01; HS: β = -0·19, P < 0·01); when repeated in normotensives, a similar relationship was observed (LS: β = -0·17, P < 0·05; HS: β = -0·18, P = 0·14). In multivariable analyses, both higher 25(OH)D levels and the T allele at Fok1 were independently associated with lower PRA in hypertensives; however, 25(OH)D was not associated with PRA in normotensives. CONCLUSIONS: Genetic variation at the Fok1 polymorphism of the VDR gene, in combination with 25(OH)D levels, was associated with PRA in hypertension. These findings support the vitamin D-VDR complex as a potential regulator of renin activity in humans.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
