Labcorp Genetics (formerly Invitae), Labcorp RCV003626340 SCV004469035 uncertain significance Cataract 13 with adult I phenotype 2023-09-06 criteria provided, single submitter clinical testing This missense change has been observed in individual(s) with congenital cataracts (Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 372 of the GCNT2 protein (p.Pro372Leu). 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 GCNT2 protein function.
