Labcorp Genetics (formerly Invitae), Labcorp RCV001313247 SCV001503734 uncertain significance Cone-rod dystrophy 6; Leber congenital amaurosis 1 2024-01-04 criteria provided, single submitter clinical testing This sequence change replaces proline, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 88 of the GUCY2D protein (p.Pro88Thr). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with GUCY2D-related conditions. ClinVar contains an entry for this variant (Variation ID: 1014506). 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 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.
