Description

This sequence change creates a premature translational stop signal (p.Leu2448Thrfs*8) in the CEP290 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 32 amino acid(s) of the CEP290 protein. This variant is present in population databases (rs281865189, gnomAD 0.003%). This premature translational stop signal has been observed in individual(s) with CEP290-related conditions (PMID: 16682973, 16909394, 29588463). This variant is also known as 7341-7342insA. ClinVar contains an entry for this variant (Variation ID: 99864). For these reasons, this variant has been classified as Pathogenic.
