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 c.7411_7413delGAA (p.E2471del) alteration is located in exon 54 (coding exon 53) of the CEP290 gene. This alteration consists of an in-frame deletion of 3 nucleotides between nucleotide positions c.7411 and c.7413, resulting in the deletion of 1 residue. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant, c.7411_7413del, results in the deletion of 1 amino acid(s) of the CEP290 protein (p.Glu2471del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs777398895, ExAC 0.003%). This variant has not been reported in the literature in individuals affected with CEP290-related conditions. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
