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]

The ERCC6 c.2047C>T (p.Arg683Ter) variant is a stop-gained variant predicted to result in premature termination of the protein. The p.Arg683Ter variant been reported in two studies in which it is found in two patients including one homozygote with cerebrooculofacioskeletal syndrome (CFSS) and one compound heterozygote with Cockayne syndrome (Laugel et al. 2008; Calmels et al. 2016). Control data are not available for the p.Arg683Ter variant which is reported at a frequency of 0.00005 in the European (non-Finnish) population of the Exome Aggregation Consortium. Western blot analysis demonstrated that the variant resulted in an absence of protein. Complementation assays in CFSS patient fibroblasts transfected with wild type ERCC6 demonstrated rescue of DNA repair deficiency (Laugel et al. 2008). Although the p.Arg683Ter variant is described in the literature in association with autosomal recessive inheritance, an increased risk for macular degeneration due to heterozygous variants may exist. Due to the potential impact of stop-gained variants and evidence from the literature, the p.Arg683Ter variant is classified as likely pathogenic for ERCC6-related disorders. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population.

This sequence change creates a premature translational stop signal (p.Arg683*) in the ERCC6 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ERCC6 are known to be pathogenic (PMID: 18628313, 29572252). This variant is present in population databases (rs121917904, gnomAD 0.006%). This premature translational stop signal has been observed in individual(s) with Cockayne syndrome (PMID: 18628313, 29572252). ClinVar contains an entry for this variant (Variation ID: 1711). For these reasons, this variant has been classified as Pathogenic.
