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]

Pathogenic, criteria provided, single submitterclinical testingInvitaeNov 08, 2022For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with XRCC4-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.003%). This sequence change creates a premature translational stop signal (p.Ala60Glufs*11) in the XRCC4 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in XRCC4 are known to be pathogenic (PMID: 25728776). -
