Variant summary
Our verdict is Pathogenic. The variant received 16 ACMG points: 16P and 0B. PVS1PP5_Very_Strong
The NM_025114.4(CEP290):c.289G>T(p.Glu97*) variant causes a stop gained change. The variant allele was found at a frequency of 0.00000673 in 1,188,814 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. E97E) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Variant summary: CEP290 c.289G>T (p.Glu97X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. The frequency data for this variant in gnomAD is considered unreliable, as metrics indicate poor data quality at this position. c.289G>T has been reported in the literature in compound heterozygous individuals affected with Meckel Syndrome Type 4 (Tallila_2009, Skorczyk-Werner_2022, Weisschuh_2020). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 31734136, 36369640, 19466712, 32531858). ClinVar contains an entry for this variant (Variation ID: 56734). Based on the evidence outlined above, the variant was classified as pathogenic. -

Meckel-Gruber syndrome;C0431399:Joubert syndrome;C0687120:Nephronophthisis Pathogenic:1
This sequence change creates a premature translational stop signal (p.Glu97*) 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 Meckel syndrome (PMID: 19466712). ClinVar contains an entry for this variant (Variation ID: 56734). 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. -
