Genes affected

ERCC8 (HGNC:3439): (ERCC excision repair 8, CSA ubiquitin ligase complex subunit) This gene encodes a WD repeat protein, which interacts with Cockayne syndrome type B (CSB) protein and with p44 protein, a subunit of the RNA polymerase II transcription factor IIH. Mutations in this gene have been identified in patients with hereditary disease Cockayne syndrome (CS). CS cells are abnormally sensitive to ultraviolet radiation and are defective in the repair of transcriptionally active genes. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2014]

Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. This premature translational stop signal has been observed in individual(s) with Cockayne syndrome (PMID: 7664335, 19894250, 29572252, 30200888). This variant is present in population databases (no rsID available, gnomAD 0.003%). This sequence change creates a premature translational stop signal (p.Tyr322*) in the ERCC8 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ERCC8 are known to be pathogenic (PMID: 29572252). For these reasons, this variant has been classified as Pathogenic. -
