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.

Pathogenic, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpJun 20, 2022Variant summary: CEP290 c.1219_1220delAT (p.Met407GlufsX14) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been classified as pathogenic by our laboratory (e.g. c.1666dupA, p.Ile556AsnfsX20; c.2722C>T, p.Arg908X; c.5182G>T, p.Glu1728X). The variant allele was found at a frequency of 7.2e-05 in 248424 control chromosomes (gnomAD). c.1219_1220delAT has been reported in the literature in multiple individuals affected with CEP290-Related Disorders including Meckel Syndrome and Leber Congenital Amaurosis (e.g. Baala_2007, Perrault_2007, Tallila_2009, Wang_2013, Astuti_2016). These data indicate that the variant is very likely to be associated with disease. Seven assessments for this variant have been submitted to ClinVar after 2014 and all classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -
Pathogenic, no assertion criteria providedclinical testingPreventionGenetics, part of Exact SciencesApr 24, 2024The CEP290 c.1219_1220delAT variant is predicted to result in a frameshift and premature protein termination (p.Met407Glufs*14). This variant has been reported to be causative for Leber congenital amaurosis and Joubert syndrome (Perrault et al. 2007. PubMed ID: 17345604; Table S5, Bachmann-Gagescu et al. 2015. PubMed ID: 26092869; Radha Rama Devi et al. 2020. PubMed ID: 32139166). This variant is reported in 0.032% of alleles in individuals of European (Finnish) descent in gnomAD. Frameshift variants in CEP290 are expected to be pathogenic. This variant is interpreted as pathogenic. -

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 30, 2024This sequence change creates a premature translational stop signal (p.Met407Glufs*14) 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 (rs386834148, gnomAD 0.03%). This premature translational stop signal has been observed in individual(s) with a spectrum of CEP290-related conditions (PMID: 17345604, 17564974, 26092869). ClinVar contains an entry for this variant (Variation ID: 56729). For these reasons, this variant has been classified as Pathogenic. -
