NCIt related terms : Pseudo Vitamin-D Deficient Rickets; Vitamin D-dependent Rickets Type 1; Vitamin D Hydroxylation-deficient Rickets type 1a; VDDR1; Selective 1-alpha, 25-hydroxyvitamin D3 deficiency; 1 Alpha-hydroxylase Deficiency;
NCIt definition : An autosomal recessive form of rickets caused by inactivating mutation(s) in the CYP27B1
gene, encoding 25-hydroxyvitamin D-1 alpha hydroxylase, the renal enzyme that converts
25-hydroxyvitamin D to 1 alpha,25-dihydroxyvitamin D (calcitriol), the active metabolite
of vitamin D (cholecalciferol). The condition is characterized by reduced serum concentrations
of 1 alpha,25-hydroxyvitamin D, normal concentrations of 25-hydroxyvitamin D, increased
serum alkaline phosphatase, hypocalcemia due to reduced intestinal calcium absorption,
hypophosphatemia due to renal phosphate wasting, secondary hyperparathyroidism, rickets,
seizures, muscle weakness and failure to thrive.;
