Genes affected

XRCC4 (HGNC:12831): (X-ray repair cross complementing 4) The protein encoded by this gene functions together with DNA ligase IV and the DNA-dependent protein kinase in the repair of DNA double-strand breaks. This protein plays a role in both non-homologous end joining and the completion of V(D)J recombination. Mutations in this gene can cause short stature, microcephaly, and endocrine dysfunction (SSMED). Alternate transcript variants such as NM_022406 are unlikely to be expressed in some individuals due to a polymorphism (rs1805377) in the last splice acceptor site. [provided by RefSeq, Oct 2019]

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on XRCC4 protein function. This variant has not been reported in the literature in individuals affected with XRCC4-related conditions. This variant is present in population databases (rs545670116, gnomAD 0.003%). This sequence change replaces methionine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 61 of the XRCC4 protein (p.Met61Val). -
