Genes affected

PTH (HGNC:9606): (parathyroid hormone) This gene encodes a member of the parathyroid family of proteins. The encoded preproprotein is proteolytically processed to generate a protein that binds to the parathyroid hormone/parathyroid hormone-related peptide receptor and regulates blood calcium and phosphate levels. Excess production of the encoded protein, known as hyperparathyroidism, can result in hypercalcemia and kidney stones. On the other hand, defective processing of the encoded protein may lead to hypoparathyroidism, which can result in hypocalcemia and numbness. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2015]

The c.247C>T;p.(Arg83*) variant creates a premature translational stop signal in the PTH gene without sufficient information about prediction of nonsense mediated mRNA decay (NMD) type change; it is present in a relevant exon to the transcript, and disrupts >10% of the protein product - PVS1_strong. This sequence change has been observed in affected individual(s) (PMID: 18784115; 1425431) - PS4_supporting. The variant is present at low allele frequencies population databases (rs6256 – gnomAD 0.00003978%; ABraOM no frequency - https://abraom.ib.usp.br/) - PM2_supporting. In summary, the currently available evidence indicates that the variant is likely pathogenic. -
