Mutations of the activating enzymes CYP2R1 and CYP27B1 cause lack of normal 1,25-(OH)<sub>2</sub>D<sub>3</sub> synthesis and result in rickets whereas mutations of the inactivating enzyme CYP24A1 cause build-up of excess 1,25-(OH)<sub>2</sub>D<sub>3</sub> and result in hypercalcemia, nephrolithiasis, and nephrocalcinosis.

Pseudovitamin D deficiency is the consequence of a genetic defect in the CYP27B1 gene resulting in diminished or absent conversion of 25-hydroxyvitamin D3 (25-(OH)D3) into 1,25-dihydroxyvitamin D3 (1,25-(OH)2D3) and leads to growth retardation and rickets, usually in the first 2 years of life.

Multiple mutations have been identified in VDR and CYP27B1 in patients with rickets, and thus, the roles of these two genes in vitamin D metabolism are unassailable.

A causative role for CYP27B1 in MS is supported; the mutations identified are known to alter function having been shown in vivo to result in rickets when 2 copies are present.

Vitamin D 1alpha-hydroxylase deficiency, also known as vitamin D-dependent rickets type 1, is an autosomal recessive disorder characterized by the early onset of rickets with hypocalcemia and is caused by mutations of the 25-hydroxyvitamin D 1alpha-hydroxylase (1alpha-hydroxylase, CYP27B1) gene.

One of three kinds of hereditary rickets (vitamin D-dependent rickets type I) displays an autosomal recessive trait and clinical features consistent with a defect of 1 alpha-hydroxylase activity, and the genetic analysis of the type I patients identified missense mutations of the 1 alpha(OH)ase gene that results in a loss of this enzymatic activity.
