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]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.03).
• BP6: Variant 13-31757975-T-C is Benign according to our data. Variant chr13-31757975-T-C is described in ClinVar as [Benign]. Clinvar id is 1257281.Status of the report is criteria_provided_single_submitter, 1 stars.
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.994 is higher than 0.05.
