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 submitter	clinical testing	GeneDx	Apr 27, 2021	Nonsense variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss-of-function is a known mechanism of disease; This variant is associated with the following publications: (PMID: 22355252, 25097241) -
Pathogenic, no assertion criteria provided	clinical testing	Department of Pathology and Laboratory Medicine, Sinai Health System	-	The CEP290 p.R360* variant was identified as a compound heterozygous variant in multiple individuals with Leber congenital amaurosis and retinitis pigmentosa (Yzer_2012_PMID: 22355252; Wang_2014_PMID: 25097241). The variant was identified in dbSNP (ID: rs776645403) and ClinVar (classified as pathogenic by Fulgent Genetics and Invitae). The variant was identified in control databases in 3 of 79762 chromosomes at a frequency of 0.00003761 (Genome Aggregation Database March 6, 2019, v2.1.1). The c.1078C>T variant leads to a premature stop codon at position 360 which is predicted to lead to a truncated or absent protein and loss of function. Loss of function variants of the CEP290 gene are a mechanism of disease in the autosomal recessive conditions: Joubert syndrome, Leber congenital amaurosis, Meckel syndrome, Senior-Loken syndrome, and Bardet-Biedl syndrome. In summary, based on the above information this variant meets our laboratoryâ€šÃ„Ã´s criteria to be classified as pathogenic. -

The CEP290 c.1078C>T variant is predicted to result in premature protein termination (p.Arg360*). This variant has been reported along with a second pathogenic CEP290 variant in individuals with autosomal recessive Leber congenital amaurosis and retinitis pigmentosa (see for example, Yzer et al. 2012. PubMed ID: 22355252, patient 15; Wang et al. 2014. PubMed ID: 25097241). To our knowledge, the c.1078C>T variant has not been reported in the homozygous state in any patients. This variant is reported in 0.018% of alleles in individuals of South Asian 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.Arg360*) 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). 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. This premature translational stop signal has been observed in individual(s) with autosomal recessive Leber congenital amaurosis and autosomal recessive retinitis pigmentosa (PMID: 22355252, 25097241). ClinVar contains an entry for this variant (Variation ID: 530911). For these reasons, this variant has been classified as Pathogenic. -
