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]

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jan 24, 2024 | This sequence change creates a premature translational stop signal (p.Arg612*) 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 (rs376526037, gnomAD 0.004%). This premature translational stop signal has been observed in individual(s) with Cockayne disease (PMID: 28440418). ClinVar contains an entry for this variant (Variation ID: 430298). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. - |

Pathogenic, criteria provided, single submitter | clinical testing | 3billion | Oct 02, 2021 | Stop-gained (nonsense): predicted to result in a loss or disruption of normal protein function through nonsense-mediated decay (NMD) or protein truncation. Multiple pathogenic variants are reported downstream of the variant (PVS1_VS). It is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.000021, PM2). The variant has been reported multiple times as an established pathogenic variant (ClinVar ID: VCV000430298.6). Therefore, this variant is classified as pathogenic according to the recommendation of ACMG/AMP guideline. - |
