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.

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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt ERCC3 protein function. ClinVar contains an entry for this variant (Variation ID: 134122). This variant has not been reported in the literature in individuals affected with ERCC3-related conditions. This variant is present in population databases (rs587778276, gnomAD 0.002%). This sequence change replaces arginine, which is basic and polar, with isoleucine, which is neutral and non-polar, at codon 736 of the ERCC3 protein (p.Arg736Ile). -
