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)

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.48).
• BP6: Variant 5-60918280-A-G is Benign according to our data. Variant chr5-60918280-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 1916019.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=0.503 with no splicing effect.
