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:2

Likely pathogenic, criteria provided, single submitter	clinical testing	Neuberg Centre For Genomic Medicine, NCGM	-	The stop gain c.2058G>A (p.Trp686Ter) variant in ERCC6 gene has been reported in ClinVar as a pathogenic variant. The variant is novel (not in any individuals) in gnomAD Exomes and in 1000 Genomes. The nucleotide change c.2058G>A in ERCC6 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates This variant is predicted to cause loss of normal protein function through protein truncation. Loss of function variants have been previously reported to be disease causing. For these reasons, this variant has been classified as Likely Pathogenic. -

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 435083). This premature translational stop signal has been observed in individual(s) with clinical features of ERCC6-related conditions (PMID: 29915382). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Trp686*) 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). -
