RCV003783695 | SCV004571425 | uncertain significance | Cone-rod dystrophy 6; Leber congenital amaurosis 1 | 2023-10-05 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with proline, which is neutral and non-polar, at codon 332 of the GUCY2D protein (p.Arg332Pro). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with Leber congenital amaurosis (PMID: 26047050, 27375279). 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 GUCY2D 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. |
