Hypoparathyroidism, also known as deficiency of parathyroid hormone, is related to hypoparathyroidism-retardation-dysmorphism syndrome and hypoparathyroidism, x-linked. An important gene associated with Hypoparathyroidism is GCM2 (Glial Cells Missing Transcription Factor 2), and among its related pathways/superpathways are Signal Transduction and Endochondral ossification with skeletal dysplasias. The drugs Betamethasone and Sodium citrate have been mentioned in the context of this disorder. Affiliated tissues include thyroid and kidney, and related phenotypes are homeostasis/metabolism and growth/size/body region
