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 GeneticsMay 03, 2023The c.973A>G (p.N325D) alteration is located in exon 13 (coding exon 13) of the RXFP1 gene. This alteration results from a A to G substitution at nucleotide position 973, causing the asparagine (N) at amino acid position 325 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
