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 testingLabcorp Genetics (formerly Invitae), LabcorpSep 03, 2022This sequence change creates a premature translational stop signal (p.Lys484Argfs*8) 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). For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 56730). This premature translational stop signal has been observed in individual(s) with Meckel-Gruber syndrome (PMID: 21068128, 23351400). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. -

Familial aplasia of the vermis Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpFeb 25, 2015This sequence change deletes 1 nucleotide from exon 15 of the CEP290 mRNA (c.1451delA), causing a frameshift at codon 484. This creates a premature translational stop signal (p.Lys484Argfs*8) and is expected to result in an absent or disrupted protein product. Truncating variants in CEP290 are known to be pathogenic. This particular truncation has been reported in the literature (PMID: 21068128, 23351400). This variant has been reported in individuals affected with Meckel-Gruber syndrome. A second causative variant was not found in these individuals (PMID: 21068128, 23351400). For these reasons, this variant has been classified as Pathogenic. -
