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]

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Nov 10, 2023	This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 112 of the ERCC2 protein (p.Arg112His). This variant is present in population databases (rs121913020, gnomAD 0.008%). This missense change has been observed in individuals with trichothiodystrophy (PMID: 7920640, 9758621). This variant is also known as a G to A mutation at position 413. ClinVar contains an entry for this variant (Variation ID: 16784). 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 expected to disrupt ERCC2 protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects ERCC2 function (PMID: 25431422). For these reasons, this variant has been classified as Pathogenic. -
