Labcorp Genetics (formerly Invitae), Labcorp RCV000636988 SCV000758436 uncertain significance Familial aplasia of the vermis; Meckel-Gruber syndrome; Nephronophthisis 2022-10-08 criteria provided, single submitter clinical testing This sequence change replaces methionine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 1723 of the CEP290 protein (p.Met1723Val). This variant is present in population databases (rs542400806, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with CEP290-related conditions. ClinVar contains an entry for this variant (Variation ID: 530914). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on CEP290 protein function. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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.
