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.

ACMG classification

Classification made for transcript

Verdict is Pathogenic. Variant got 12 ACMG points.

PVS1
Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.010349463 fraction of the gene. No cryptic splice site detected. Exon removal is inframe change.
PM2
Very rare variant in population databases, with high coverage;
PP5
Variant 12-88140955-C-T is Pathogenic according to our data. Variant chr12-88140955-C-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 461777.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr12-88140955-C-T is described in Lovd as [Likely_pathogenic].

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpSep 22, 2023This sequence change affects a donor splice site in intron 3 of the CEP290 gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in CEP290 are known to be pathogenic (PMID: 16909394, 17345604, 20690115). This variant is present in population databases (rs758593134, gnomAD 0.001%). Disruption of this splice site has been observed in individual(s) with Leber congenital amaurosis (PMID: 16909394; Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 461777). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
