Genes affected
PTH1R (HGNC:9608): (parathyroid hormone 1 receptor) The protein encoded by this gene is a member of the G-protein coupled receptor family 2. This protein is a receptor for parathyroid hormone (PTH) and for parathyroid hormone-like hormone (PTHLH). The activity of this receptor is mediated by G proteins which activate adenylyl cyclase and also a phosphatidylinositol-calcium second messenger system. Defects in this receptor are known to be the cause of Jansen's metaphyseal chondrodysplasia (JMC), chondrodysplasia Blomstrand type (BOCD), as well as enchodromatosis. Two transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, May 2010]

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 23, 2023This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 46 of the PTH1R protein (p.Ala46Thr). This variant is present in population databases (rs201320537, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with PTH1R-related conditions. ClinVar contains an entry for this variant (Variation ID: 2171817). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
