Genes affected

ERCC4 (HGNC:3436): (ERCC excision repair 4, endonuclease catalytic subunit) The protein encoded by this gene forms a complex with ERCC1 and is involved in the 5' incision made during nucleotide excision repair. This complex is a structure specific DNA repair endonuclease that interacts with EME1. Defects in this gene are a cause of xeroderma pigmentosum complementation group F (XP-F), or xeroderma pigmentosum VI (XP6).[provided by RefSeq, Mar 2009]

For these reasons, this variant has been classified as Pathogenic. This variant has been observed in individual(s) with clinical features of Cockayne syndrome (PMID: 23623389). ClinVar contains an entry for this variant (Variation ID: 55828). This variant is present in population databases (rs747759202, ExAC 0.006%). This sequence change creates a premature translational stop signal (p.Tyr577*) in the ERCC4 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ERCC4 are known to be pathogenic (PMID: 9580660). -
