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.

The R151X variant in the CEP290 gene has been reported previously in association with Leber congenital amaurosis, early-onset severe retinal dystrophy, and a nonspecified retinal dystrophy (Littink et al., 2010; Huang et al., 2015). This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. The R151X variant was not observed in approximately 5,800 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. Based on currently available evidence, we interpret R151X as a pathogenic variant. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The CEP290 c.451C>T;p.Arg151Ter variant has been described in at least one individual with retinal dystrophy (Huang 2015) and one family with early onset severe retinal dystrophy and Leber congential amaurosis (Littink 2010). The variant is listed in the ClinVar database (Variation ID: 372761) and the dbSNP variant database (rs757641323) but is not listed in the general population-based databases (Exome Variant Server, Genome Aggregation Database). The variant introduces a premature termination codon, but at least one report shows that this variant leads to a skipping of exon 7 or exon 7 and 8, which leads to an in-frame product lacking a portion of a functional domain. Considering available information, this variant is classified as likely pathogenic. References: Huang XF et al. Genotype-phenotype correlation and mutation spectrum in a large cohort of patients with inherited retinal dystrophy revealed by next-generation sequencing. Genet Med. 2015 Apr;17(4):271-8.

The c.451C>T (p.R151*) alteration, located in exon 7 (coding exon 6) of the CEP290 gene, consists of a C to T substitution at nucleotide position 451. This changes the amino acid from an arginine (R) to a stop codon at amino acid position 151. This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. Based on data from gnomAD, the T allele has an overall frequency of 0.001% (1/108296) total alleles studied. The highest observed frequency was 0.002% (1/49182) of European (non-Finnish) alleles. This variant has been identified in the homozygous state and/or in conjunction with other variant(s) in this same gene in individual(s) with features consistent with Leber congenital amaurosis and segregated with disease in at least one family (Huang, 2015; Roosing, 2017; Littink, 2010; external communication). RNA studies have demonstrated that this alteration results in transcripts predicted to lead to protein products with in-frame deletions of 18 or 25 amino acid(s); however, the exact functional impact of the deleted amino acid(s) is unknown at this time (Littink, 2010). Based on the available evidence, this alteration is classified as pathogenic. -

This sequence change creates a premature translational stop signal (p.Arg151*) in the CEP290 gene. RNA analysis indicates that this premature translational stop signal induces altered splicing and likely results in a shortened protein product. 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 individuals with retinal dystrophy (PMID: 20130272, 25356976, 28829391; Invitae). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 372761). Studies have shown that this premature translational stop signal results in skipping of exon 7 or exons 7-8, but is expected to preserve the integrity of the reading-frame (PMID: 20130272). For these reasons, this variant has been classified as Pathogenic. -

Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Pathogenic. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with Joubert syndrome 5 (MIM#610188), Leber congenital amaurosis 10 (MIM#611755), Meckel syndrome 4 (MIM#611134) and Senior-Loken syndrome 6 (MIM#610189). (I) 0106 - This gene is associated with autosomal recessive disease. (I) 0209 - Variant proven to affect splicing of the transcript with uncertain effect on protein sequence. RT-PCR experiments using patient cDNA have demonstrated that this variant results in in-frame skipping of either exon 7 (p.(Leu148_Glu165del)) or exon 7 and exon 8 (p.(Leu148_Lys172del)) (PMIDs: 20130272, 28829391). (SP) 0251 - This variant is heterozygous. (I) 0304 - Variant is present in gnomAD <0.01 for a recessive condition (v3: 1 heterozygote, 0 homozygotes). (SP) 0604 - Variant is not located in an established domain, motif, hotspot or informative constraint region. (I) 0801 - This variant has strong previous evidence of pathogenicity in unrelated individuals. This variant has been classified as likely pathogenic and pathogenic by multiple clinical diagnostic laboratories and has been reported as compound heterozygous in multiple individuals with Leber congenital amaurosis, early-onset severe retinal dystrophy or oligocone trichromacy (PMIDs: 20130272, 28829391, 25356976, 27208204). (SP) 1201 - Heterozygous variant detected in trans with a second pathogenic heterozygous variant (NM_025114.3(CEP290):c.2506G>T; p.(Glu836*)) in a recessive disease. (SP) 1205 - This variant has been shown to be maternally inherited (by segregation testing). (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign -
