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]

The c.215G>A (p.G72E) alteration is located in exon 2 (coding exon 2) of the RXFP2 gene. This alteration results from a G to A substitution at nucleotide position 215, causing the glycine (G) at amino acid position 72 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
