Labcorp Genetics (formerly Invitae), Labcorp RCV001049171 SCV001213206 uncertain significance not provided 2022-06-08 criteria provided, single submitter clinical testing This sequence change replaces phenylalanine, which is neutral and non-polar, with cysteine, which is neutral and slightly polar, at codon 323 of the CNGB3 protein (p.Phe323Cys). This variant is present in population databases (rs759770735, gnomAD 0.06%). This variant has not been reported in the literature in individuals affected with CNGB3-related conditions. ClinVar contains an entry for this variant (Variation ID: 845984). 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 CNGB3 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.
