Invitae RCV003603929 SCV004547960 uncertain significance Exostoses, multiple, type 2 2023-05-02 criteria provided, single submitter clinical testing 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. 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 expected to disrupt EXT2 protein function. This variant has not been reported in the literature in individuals affected with EXT2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces valine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 479 of the EXT2 protein (p.Val479Glu).
