Genes affected

ERCC2 (HGNC:3434): (ERCC excision repair 2, TFIIH core complex helicase subunit) The nucleotide excision repair pathway is a mechanism to repair damage to DNA. The protein encoded by this gene is involved in transcription-coupled nucleotide excision repair and is an integral member of the basal transcription factor BTF2/TFIIH complex. The gene product has ATP-dependent DNA helicase activity and belongs to the RAD3/XPD subfamily of helicases. Defects in this gene can result in three different disorders, the cancer-prone syndrome xeroderma pigmentosum complementation group D, trichothiodystrophy, and Cockayne syndrome. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2008]

Variant summary: ERCC2 c.2083C>T (p.Arg695Cys) results in a non-conservative amino acid change located in the ATP-dependent helicase, C-terminal domain (IPR006555) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00014 in 251314 control chromosomes (gnomAD). This frequency is not significantly higher than expected for a pathogenic variant in ERCC2 causing Xeroderma Pigmentosum (0.00014 vs 0.00061), allowing no conclusion about variant significance. c.2083C>T has been reported in the literature in individuals affected with medulloblastoma (Trubicka_2017) and Osteosarcoma (Zhang_2015). These reports do not provide unequivocal conclusions about association of the variant with Xeroderma Pigmentosum or Trichothiodystrophy. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Two ClinVar submitters have assessed this variant since 2014: all have classified the variant as of uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 695 of the ERCC2 protein (p.Arg695Cys). This variant is present in population databases (rs201392911, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with ERCC2-related conditions. ClinVar contains an entry for this variant (Variation ID: 134101). 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 ERCC2 protein function. 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. -
