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]

The c.2545C>G (p.Q849E) alteration is located in exon 11 (coding exon 11) of the ERCC4 gene. This alteration results from a C to G substitution at nucleotide position 2545, causing the glutamine (Q) at amino acid position 849 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Based on the classification scheme VCGS_Germline_v1.1.1, this variant is classified as likely benign. Following criteria are met: 0102 - Loss-of-function is a known mechanism of disease for this gene. (N) 0106 - This gene is known to be associated with autosomal recessive disease. (N) 0200 - Variant is predicted to result in a missense amino acid change from glutamine to glutamic acid (exon 11). (N) 0252 - Variant is homozygous. (N) 0304 - Variant is present in gnomAD <0.01 for a recessive condition (23 heterozygotes, 1 homozygote). (P) 0309 - An alternative amino acid change at the same position has been observed in gnomAD (p.(Gln849Leu); 9 heterozygotes, 0 homozygotes). (N) 0503 - Missense variant consistently predicted to be tolerated or not conserved in mammals with a minor amino acid change. (B) 0600 - Variant is located in an annotated domain or motif (Rad1 superfamily; NCBI)(N) 0705 - No comparable variants have previous evidence for pathogenicity. (N) 0806 - Moderate previous evidence of neutrality in unrelated individuals (ClinVar). (B) 0905 - No segregation evidence has been identified for this variant. (N) 1007 - No published functional evidence has been identified for this variant. (N) 1205 - Variant is bialleic. (N) Legend: (P) - Pathogenic, (N) - Neutral, (B) - Benign -
