Invitae | RCV001223714 | SCV001395873 | uncertain significance | Fibrous dysplasia of jaw | 2023-12-09 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 298 of the SH3BP2 protein (p.Arg298Trp). This variant is present in population databases (rs776406405, gnomAD 0.02%), including at least one homozygous and/or hemizygous individual. This variant has not been reported in the literature in individuals affected with SH3BP2-related conditions. ClinVar contains an entry for this variant (Variation ID: 951732). 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 SH3BP2 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. |
