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 testingLabcorp Genetics (formerly Invitae), LabcorpJun 27, 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 0.01%). This sequence change creates a premature translational stop signal (p.Ser12Leufs*5) 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). -
