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]

Cockayne syndrome;C0268140:Xeroderma pigmentosum, group F;C3808988:Fanconi anemia complementation group Q Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 20, 2020For 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). -
