Labcorp Genetics (formerly Invitae), Labcorp RCV001363417 SCV001559528 uncertain significance Fanconi anemia 2022-10-13 criteria provided, single submitter clinical testing This sequence change replaces cysteine, which is neutral and slightly polar, with tyrosine, which is neutral and polar, at codon 340 of the FANCG protein (p.Cys340Tyr). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with FANCG-related conditions. ClinVar contains an entry for this variant (Variation ID: 1054834). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on FANCG protein function. 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.
