RCV002547591 | SCV003458622 | uncertain significance | Xeroderma pigmentosum, group F; Cockayne syndrome; Fanconi anemia complementation group Q | 2023-08-16 | criteria provided, single submitter | clinical testing | Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt ERCC4 protein function. ClinVar contains an entry for this variant (Variation ID: 1049071). This variant has not been reported in the literature in individuals affected with ERCC4-related conditions. This variant is present in population databases (rs775257742, gnomAD 0.002%). This sequence change replaces serine, which is neutral and polar, with arginine, which is basic and polar, at codon 96 of the ERCC4 protein (p.Ser96Arg). 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. |

RCV001354691 | SCV001549368 | uncertain significance | not provided | no assertion criteria provided | clinical testing | The ERCC4 p.Ser96Arg variant was not identified in the literature nor was it identified in ClinVar, Cosmic or LOVD 3.0. The variant was identified in dbSNP (ID: rs775257742) and in control databases in 4 of 282774 chromosomes at a frequency of 0.00001415 (Genome Aggregation Database March 6, 2019, v2.1.1). The variant was observed in the European (non-Finnish) population in 4 of 129120 chromosomes (freq: 0.000031), but was not observed in the African, Latino, Ashkenazi Jewish, East Asian, European (Finnish), Other, or South Asian populations. The p.Ser96 residue is not conserved in mammals and four out of five computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; however, this information is not predictive enough to rule out pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. |
