Variant summary
Our verdict is Uncertain significance. The variant received 0 ACMG points: 0P and 0B.
The NM_000400.4(ERCC2):c.679C>T(p.Arg227Cys) variant causes a missense change. The variant allele was found at a frequency of 0.000117 in 1,613,902 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R227H) has been classified as Uncertain significance.

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 227 of the ERCC2 protein (p.Arg227Cys). This variant is present in population databases (rs137910235, gnomAD 0.09%). This missense change has been observed in individual(s) with ERCC2-related conditions (PMID: 34930662). ClinVar contains an entry for this variant (Variation ID: 134116). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt ERCC2 protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
