Genes affected

ERCC4 (HGNC:3436): (ERCC excision repair 4, endonuclease catalytic subunit) The protein encoded by this gene forms a complex with ERCC1 and is involved in the 5' incision made during nucleotide excision repair. This complex is a structure specific DNA repair endonuclease that interacts with EME1. Defects in this gene are a cause of xeroderma pigmentosum complementation group F (XP-F), or xeroderma pigmentosum VI (XP6).[provided by RefSeq, Mar 2009]

ACMG classification

Verdict is Uncertain_significance. Variant got 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.937
• PP5: Variant 16-13928132-T-C is Pathogenic according to our data. Variant chr16-13928132-T-C is described in ClinVar as [Pathogenic]. Clinvar id is 55826.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr16-13928132-T-C is described in Lovd as [Pathogenic].
