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]

Collection Method:clinical testing

The c.110A>C (p.Q37P) alteration is located in exon 2 (coding exon 2) of the RXFP2 gene. This alteration results from a A to C substitution at nucleotide position 110, causing the glutamine (Q) at amino acid position 37 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
