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 GeneticsDec 28, 2022The c.738G>A (p.M246I) alteration is located in exon 9 (coding exon 9) of the RXFP1 gene. This alteration results from a G to A substitution at nucleotide position 738, causing the methionine (M) at amino acid position 246 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
