Genes affected

PTH2R (HGNC:9609): (parathyroid hormone 2 receptor) The protein encoded by this gene is a member of the G-protein coupled receptor 2 family. This protein is a receptor for parathyroid hormone (PTH). This receptor is more selective in ligand recognition and has a more specific tissue distribution compared to parathyroid hormone receptor 1 (PTHR1). It is activated only by PTH and not by parathyroid hormone-like hormone (PTHLH) and is particularly abundant in brain and pancreas. Alternative splicing results in multiple transcript variants.

Dec 19, 2023

The c.373T>A (p.C125S) alteration is located in exon 4 (coding exon 4) of the PTH2R gene. This alteration results from a T to A substitution at nucleotide position 373, causing the cysteine (C) at amino acid position 125 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
