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]

This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 709 of the ERCC4 protein (p.Val709Met). This variant is present in population databases (rs373906926, gnomAD 0.006%). This missense change has been observed in individual(s) with head and neck squamous cell carcinoma (PMID: 28678401). ClinVar contains an entry for this variant (Variation ID: 474203). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. -
