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]

St. Jude Molecular Pathology, St. Jude Children's Research Hospital
Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The ERCC4 c.1606G>C (p.Val536Leu) missense change has a maximum subpopulation frequency of 0.072% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/). The in silico tool REVEL predicts a benign effect on protein function, but this prediction has not been confirmed by functional studies. This variant has not been reported in individuals with Fanconi anemia or xeroderma pigmentosum. In summary, the evidence currently available is insufficient to determine the clinical significance of this variant. It has therefore been classified as of uncertain significance. -
