Labcorp Genetics (formerly Invitae), Labcorp RCV002541726 SCV003479490 uncertain significance Familial aplasia of the vermis; Meckel-Gruber syndrome; Nephronophthisis 2022-08-08 criteria provided, single submitter clinical testing This sequence change replaces methionine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 559 of the CEP290 protein (p.Met559Ile). This variant is present in population databases (no rsID available, gnomAD 0.03%). 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: 991677). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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.

PreventionGenetics, part of Exact Sciences RCV004733224 SCV005367201 uncertain significance CEP290-related disorder 2024-09-20 no assertion criteria provided clinical testing The CEP290 c.1677G>C variant is predicted to result in the amino acid substitution p.Met559Ile. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.029% of alleles in individuals of Latino descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
