Description

For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the CEP290 protein in which other variant(s) (p.Tyr2429Serfs*8) have been determined to be pathogenic (Invitae). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. ClinVar contains an entry for this variant (Variation ID: 1419020). This variant has not been reported in the literature in individuals affected with CEP290-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Glu2412Asnfs*24) in the CEP290 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 68 amino acid(s) of the CEP290 protein.
