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.

The c.553G>A (p.V185M) alteration is located in exon 6 (coding exon 6) of the PTH2R gene. This alteration results from a G to A substitution at nucleotide position 553, causing the valine (V) at amino acid position 185 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
