Description

The CEP290 c.7341dupA variant is predicted to result in a frameshift and premature protein termination (p.Leu2448Thrfs*8). This variant has been reported in the compound heterozygous state with a second pathogenic CEP290 variant in multiple individuals affected with Joubert syndrome, end-stage renal disease, and/or early onset severe retinal dystrophy (for example, see Supplementary Table S5 at Chaki. 2011. PubMed ID: 21866095; Feldhaus et al. 2020. PubMed ID: 31734136; Sayer et al. 2006. PubMed ID: 16682973). This variant is reported in 0.0097% of alleles in individuals of Ashkenazi Jewish descent in gnomAD. This variant is located in the last exon of CEP290 and therefore not predicted to undergo nonsense-mediated mRNA decay; however, other premature truncation variants in CEP290 have been reported both up- and downstream of this variant in the same exon (Human Gene Mutation Database, HGMD). This variant is interpreted as pathogenic.
