Genes affected
RXFP1 (HGNC:19718): (relaxin family peptide receptor 1) This gene encodes a member of the leucine-rich repeat-containing subgroup of the G protein-coupled 7-transmembrane receptor superfamily. The encoded protein plays a critical role in sperm motility, pregnancy and parturition as a receptor for the protein hormone relaxin. Decreased expression of this gene may play a role in endometriosis. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2021The c.1670A>G (p.Y557C) alteration is located in exon 16 (coding exon 16) of the RXFP1 gene. This alteration results from a A to G substitution at nucleotide position 1670, causing the tyrosine (Y) at amino acid position 557 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
