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.

This sequence change creates a premature translational stop signal (p.Arg621Ilefs*2) 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). This variant is present in population databases (rs766608755, gnomAD 0.004%). This premature translational stop signal has been observed in individuals with CEP290-related conditions (PMID: 17345604, 27894351). This variant is also known as c.1855-1858delAAAG. ClinVar contains an entry for this variant (Variation ID: 194988). For these reasons, this variant has been classified as Pathogenic. -
