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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 22, 2023The c.137G>T (p.R46L) alteration is located in exon 1 (coding exon 1) of the AVPR1A gene. This alteration results from a G to T substitution at nucleotide position 137, causing the arginine (R) at amino acid position 46 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
