Genes affected

RXFP2 (HGNC:17318): (relaxin family peptide receptor 2) This gene encodes a member of the GPCR (G protein-coupled, 7-transmembrane receptor) family. Mutations in this gene are associated with cryptorchidism. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Oct 2009]

Jun 09, 2022

The c.73A>G (p.I25V) alteration is located in exon 1 (coding exon 1) of the RXFP2 gene. This alteration results from a A to G substitution at nucleotide position 73, causing the isoleucine (I) at amino acid position 25 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
