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]

Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. This variant has not been reported in the literature in individuals affected with ERCC4-related conditions. This variant is present in population databases (rs750358005, gnomAD 0.01%). This sequence change replaces methionine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 12 of the ERCC4 protein (p.Met12Val). 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. -
