Summaries for Hypocalciuric Hypercalcemia, Familial, Type Ii

UniProtKB/Swiss-Prot : 75 Hypocalciuric hypercalcemia, familial 2: A form of hypocalciuric hypercalcemia, a disorder of mineral homeostasis that is transmitted as an autosomal dominant trait with a high degree of penetrance. It is characterized biochemically by lifelong elevation of serum calcium concentrations and is associated with inappropriately low urinary calcium excretion and a normal or mildly elevated circulating parathyroid hormone level. Hypermagnesemia is typically present. Affected individuals are usually asymptomatic and the disorder is considered benign. However, chondrocalcinosis and pancreatitis occur in some adults.

MalaCards based summary : Hypocalciuric Hypercalcemia, Familial, Type Ii, also known as hhc2, is related to familial hypocalciuric hypercalcemia and hyperparathyroidism, neonatal severe. An important gene associated with Hypocalciuric Hypercalcemia, Familial, Type Ii is GNA11 (G Protein Subunit Alpha 11), and among its related pathways/superpathways are Fatty acid metabolism and Phenylalanine metabolism. Affiliated tissues include bone and liver, and related phenotypes are multiple lipomas and pancreatitis

Disease Ontology : 12 A familial hypocalciuric hypercalcemia that has material basis in heterozygous mutation in the GNA11 gene on chromosome 19p13.
