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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 20, 2023The c.227A>G (p.D76G) alteration is located in exon 2 (coding exon 2) of the RXFP2 gene. This alteration results from a A to G substitution at nucleotide position 227, causing the aspartic acid (D) at amino acid position 76 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
