Vitamin D Pathway
Variations in receptors like VDR and binding proteins affecting serum concentrations and sunlight synthesis responses.
Biological Mechanism & Scientific Context
Circulating 25(OH)D levels reflect a combination of dermal UV synthesis, dietary intake, hepatic 25-hydroxylation (CYP2R1), serum transport (GC protein), and nuclear receptor sensitivity (VDR). Genetic variations explain why identical sun exposure yields disparate blood levels.
