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.4837C>G (p.P1613A) alteration is located in exon 37 (coding exon 36) of the CEP290 gene. This alteration results from a C to G substitution at nucleotide position 4837, causing the proline (P) at amino acid position 1613 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

The CEP290 c.4837C>G variant is predicted to result in the amino acid substitution p.Pro1613Ala. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0078% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/12-88476983-G-C). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

This sequence change replaces proline, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 1613 of the CEP290 protein (p.Pro1613Ala). This variant is present in population databases (rs769280708, gnomAD 0.008%). This variant has not been reported in the literature in individuals affected with CEP290-related conditions. ClinVar contains an entry for this variant (Variation ID: 530920). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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. -
