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.41G>C (p.R14T) alteration is located in exon 1 (coding exon 1) of the RXFP2 gene. This alteration results from a G to C substitution at nucleotide position 41, causing the arginine (R) at amino acid position 14 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
