Genes affected
ERCC3 (HGNC:3435): (ERCC excision repair 3, TFIIH core complex helicase subunit) This gene encodes an ATP-dependent DNA helicase that functions in nucleotide excision repair. The encoded protein is a subunit of basal transcription factor 2 (TFIIH) and, therefore, also functions in class II transcription. Mutations in this gene are associated with Xeroderma pigmentosum B, Cockayne's syndrome, and trichothiodystrophy. Alternative splicing results in multiple transcript variants.

Submissions by phenotype

not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpSep 01, 2022This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 765 of the ERCC3 protein (p.Arg765Trp). This variant is present in population databases (rs774571443, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with ERCC3-related conditions. ClinVar contains an entry for this variant (Variation ID: 1428473). 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: "Possibly 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. -
