Labcorp Genetics (formerly Invitae), Labcorp RCV001903119 SCV002161044 uncertain significance Retinitis pigmentosa 12; Leber congenital amaurosis 8 2022-07-06 criteria provided, single submitter clinical testing This sequence change replaces valine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 578 of the CRB1 protein (p.Val578Leu). This variant is present in population databases (rs769859765, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with CRB1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1396683). 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 CRB1 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.
