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)

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2022The c.379T>C (p.W127R) alteration is located in exon 4 (coding exon 4) of the ERCC8 gene. This alteration results from a T to C substitution at nucleotide position 379, causing the tryptophan (W) at amino acid position 127 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
