Genes affected

AVPR1A (HGNC:895): (arginine vasopressin receptor 1A) The protein encoded by this gene acts as receptor for arginine vasopressin. This receptor belongs to the subfamily of G-protein coupled receptors which includes AVPR1B, V2R and OXT receptors. Its activity is mediated by G proteins which stimulate a phosphatidylinositol-calcium second messenger system. The receptor mediates cell contraction and proliferation, platelet aggregation, release of coagulation factor and glycogenolysis. [provided by RefSeq, Jul 2008]

The c.1038G>T (p.W346C) alteration is located in exon 2 (coding exon 2) of the AVPR1A gene. This alteration results from a G to T substitution at nucleotide position 1038, causing the tryptophan (W) at amino acid position 346 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
