Gene: [12q133/CYP27B1] cytochrome P450, subfamily XXVIIB (25-hydroxyvitamin D3-1-alpha-hydroxylase), polypeptide 1; pseudovitamin D deficiency rickets (vitamin D dependency 1);

ASS	Vitamin D dependency 1 is thought to be related to the deficiency of a renal enzyme, 25-hydroxycholecalciferol hydroxylase."
HET	The gene for vitamin D receptor is mapped to the same chromosome (GEM:12q1/VDR). Its defect determines vitamin D dependency 2."
