Genes affected
ERCC6 (HGNC:3438): (ERCC excision repair 6, chromatin remodeling factor) This gene encodes a DNA-binding protein that is important in transcription-coupled excision repair. The encoded protein has ATP-stimulated ATPase activity, interacts with several transcription and excision repair proteins, and may promote complex formation at DNA repair sites. Mutations in this gene are associated with Cockayne syndrome type B and cerebrooculofacioskeletal syndrome 1. Alternative splicing occurs between a splice site from exon 5 of this gene to the 3' splice site upstream of the open reading frame (ORF) of the adjacent gene, piggyback-derived-3 (GeneID:267004), which activates the alternative polyadenylation site downstream of the piggyback-derived-3 ORF. The resulting transcripts encode a fusion protein that shares sequence with the product of each individual gene. [provided by RefSeq, Mar 2016]

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpMar 14, 2022This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 1215 of the ERCC6 protein (p.Ala1215Thr). This variant is present in population databases (rs377041857, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with ERCC6-related conditions. ClinVar contains an entry for this variant (Variation ID: 235487). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. 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. -

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 16, 2021The c.3643G>A (p.A1215T) alteration is located in exon 18 (coding exon 17) of the ERCC6 gene. This alteration results from a G to A substitution at nucleotide position 3643, causing the alanine (A) at amino acid position 1215 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
