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.

Submissions by phenotype
Inborn genetic diseases Uncertain:1
| Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jan 26, 2022 | The c.7276G>A (p.D2426N) alteration is located in exon 54 (coding exon 53) of the CEP290 gene. This alteration results from a G to A substitution at nucleotide position 7276, causing the aspartic acid (D) at amino acid position 2426 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
Senior-Loken syndrome 6 Uncertain:1
| Uncertain significance, criteria provided, single submitter | clinical testing | Illumina Laboratory Services, Illumina | Jan 12, 2018 | This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. - |
CEP290-related disorder Uncertain:1
| Uncertain significance, no assertion criteria provided | clinical testing | PreventionGenetics, part of Exact Sciences | Mar 03, 2024 | The CEP290 c.7276G>A variant is predicted to result in the amino acid substitution p.Asp2426Asn. This variant has been reported in an individual with retinal and optical nerve disorder (Table S12, DiΓ±eiro et al. 2020. PubMed ID: 32483926). This variant is reported in 0.019% of alleles in individuals of European (Non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. - |
Leber congenital amaurosis 10 Uncertain:1

Bardet-Biedl syndrome 14 Uncertain:1

Meckel-Gruber syndrome;C0431399:Familial aplasia of the vermis;C0687120:Nephronophthisis Uncertain:1
| Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Oct 05, 2022 | This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 2426 of the CEP290 protein (p.Asp2426Asn). This variant is present in population databases (rs200178519, gnomAD 0.02%). 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: 310586). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. - |

Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation.
