Summaries for Hypercalcemia, Infantile, 1

OMIM : 57 Infantile hypercalcemia is characterized by severe hypercalcemia, failure to thrive, vomiting, dehydration, and nephrocalcinosis. An epidemic of idiopathic infantile hypercalcemia occurred in the United Kingdom in the 1950s after the implementation of an increased prophylactic dose of vitamin D supplementation; however, the fact that most infants receiving the prophylaxis remained unaffected suggested that an intrinsic hypersensitivity to vitamin D might be implicated in the pathogenesis (summary by Schlingmann et al., 2011). (143880)

MalaCards based summary : Hypercalcemia, Infantile, 1, also known as idiopathic hypercalcemia of infancy, is related to hypocalciuric hypercalcemia, familial, type i and hypocalciuric hypercalcemia, familial, type ii. An important gene associated with Hypercalcemia, Infantile, 1 is CYP24A1 (Cytochrome P450 Family 24 Subfamily A Member 1), and among its related pathways/superpathways are Steroid biosynthesis and Peptide ligand-binding receptors. The drugs Betamethasone and Cinacalcet have been mentioned in the context of this disorder. Affiliated tissues include bone, breast and kidney, and related phenotypes are nephrolithiasis and intellectual disability

KEGG : 37
Idiopathic infantile hypercalcemia is autosomal recessive disorder that is characterized by severe hypercalcemia, failure to thrive, vomiting, dehydration, and nephrocalcinosis. It has been reported that mutations in the vitamin D-metabolizing enzyme CYP24A1 cause this disease. The presence of CYP24A1 mutations explains the increased sensitivity to vitamin D in patients with idiopathic infantile hypercalcemia.

UniProtKB/Swiss-Prot : 74 Hypercalcemia, infantile, 1: A disorder characterized by abnormally high level of calcium in the blood, failure to thrive, vomiting, dehydration, and nephrocalcinosis.
