Variant summary

Our verdict is Pathogenic. Variant got 12 ACMG points: 12P and 0B. PM2 PP3_Moderate PP5_Very_Strong

The NM_005236.3(ERCC4):c.2065C>A(p.Arg689Ser) variant causes a missense change. The variant allele was found at a frequency of 0.00000205 in 1,461,852 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R689C) has been classified as Uncertain significance.

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 Pathogenic. Variant got 12 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.922
• PP5: Variant 16-13947661-C-A is Pathogenic according to our data. Variant chr16-13947661-C-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 55824.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr16-13947661-C-A is described in Lovd as [Likely_pathogenic]. Variant chr16-13947661-C-A is described in Lovd as [Pathogenic].

This variant has been observed in an individual affected with Fanconi anemia (PMID: 23623386). In this individual the data is consistent with the variant being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 55824). This variant has been reported to affect ERCC4 protein function (PMID: 23623386, 30165384, 28292785, 30658521). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. This variant is present in population databases (rs149364215, ExAC 0.003%). This sequence change replaces arginine with serine at codon 689 of the ERCC4 protein (p.Arg689Ser). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and serine. -
