Cytochrome P450, family 24, subfamily A, polypeptide 1

The CYP24A1 gene encodes a member of the cytochrome P450 superfamily of enzymes. Its physiological role is degradation of 1,25-dihydroxyvitamin D3, calcitriol, the physiologically active form of vitamin D3. Conclusively, loss-of-function mutations cause symptoms resembling vitamin D hypervitamonosis, especially prominent after Vitamin D administration. Infantile hypercalcemia is an autosomal recessive disorder caused by mutations of the CYP24A1 gene.
