Genes affected

CEP290 (HGNC:29021): (centrosomal protein 290) This gene encodes a protein with 13 putative coiled-coil domains, a region with homology to SMC chromosome segregation ATPases, six KID motifs, three tropomyosin homology domains and an ATP/GTP binding site motif A. The protein is localized to the centrosome and cilia and has sites for N-glycosylation, tyrosine sulfation, phosphorylation, N-myristoylation, and amidation. Mutations in this gene have been associated with Joubert syndrome and nephronophthisis and the presence of antibodies against this protein is associated with several forms of cancer.

The CEP290 c.5344C>T variant is predicted to result in premature protein termination (p.Arg1782*). This variant has been reported in individuals with Leber congenital amaurosis (Coppieters et al. 2010. PubMed ID: 20683928; Bachmann-Gagescu et al. 2015. PubMed ID: 26092869) and Joubert syndrome (Fleming et al. 2017. PubMed ID: 29146704). This variant is reported in 0.0088% of alleles in individuals of African descent in gnomAD. Nonsense variants in CEP290 are expected to be pathogenic. This variant is interpreted as pathogenic. -

The R1782X nonsense variant in the CEP290 gene has been reported previously in association with Leber congenital amaurosis (LCA) (Coppieters et al., 2010). This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. -

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 217636). This premature translational stop signal has been observed in individuals with CEP290-related conditions (PMID: 20683928, 29146704). This variant is present in population databases (rs575767207, gnomAD 0.009%). This sequence change creates a premature translational stop signal (p.Arg1782*) in the CEP290 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CEP290 are known to be pathogenic (PMID: 16909394, 17345604, 20690115). -
