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]
ERCC8-AS1 (HGNC:40220): (ERCC8 antisense RNA 1)

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 24, 2024This sequence change creates a premature translational stop signal (p.Leu132Asnfs*6) 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). This variant is present in population databases (rs774542633, gnomAD 0.006%). This premature translational stop signal has been observed in individuals with Cockayne syndrome (PMID: 26173784, 29057985). ClinVar contains an entry for this variant (Variation ID: 554811). For these reasons, this variant has been classified as Pathogenic. -
