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.

This variant was previously reported in families with Joubert syndrome and Leber congenital amaurosis and observed to segregate with Leber congenital amaurosis. It has been observed in combination with another CEP290 variant in unrelated individuals affected with Leber congenital amaurosis [PMID: 29398085, 20683928]. Loss-of-function variants in the CEP290 gene are known to be pathogenic [PMID: 16909394, 17345604, 20690115]. -

This sequence change in CEP290 is a nonsense variant predicted to cause a premature stop codon, p.(Arg1465*), in biologically relevant-exon X/Y leading to nonsense-mediated decay in a gene in which loss-of-function is an established disease mechanism (ClinGen). The highest population minor allele frequency in gnomAD v2.1 is 0.006% (2/35,222 alleles) in the Latino/admixed American population, which is consistent with recessive disease. This variant has been detected homozygous and compound heterozygous with a second allele in multiple individuals with ciliopathy phenotypes (PMID: 17564967, 20683928, 35005812). Based on the classification scheme RMH Modified ACMG Guidelines v1.5.1, this variant is classified as PATHOGENIC. Following criteria are met: PVS1, PM3, PM2_Supporting. -

The CEP290 c.4393C>T variant is predicted to result in premature protein termination (p.Arg1465*). This variant has been reported in the homozygous state as causative for Joubert syndrome (Bachmann-Gagescu et al. 2015. PubMed ID: 26092869), and in the compound heterozygous state as causative for Leber congenital amaurosis (Coppieters et al. 2010. PubMed ID: 20683928; Bravo-Gil et al. 2017. PubMed ID: 28157192; Sheck et al. 2018. PubMed ID: 29398085). This variant is reported in 0.0057% of alleles in individuals of Latino descent in gnomAD. Nonsense variants in CEP290 are expected to be pathogenic. This variant is interpreted as pathogenic. -

This sequence change creates a premature translational stop signal (p.Arg1465*) 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 (rs539400286, gnomAD 0.006%). This premature translational stop signal has been observed in individuals with Leber congenital amaurosis (PMID: 20683928, 29398085). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 217626). For these reasons, this variant has been classified as Pathogenic. -
