Variant summary
Our verdict is Pathogenic. The variant received 16 ACMG points: 16P and 0B. PVS1PP5_Very_Strong
The NM_025114.4(CEP290):c.5344C>T(p.Arg1782*) variant causes a stop gained change. The variant allele was found at a frequency of 0.0000113 in 1,590,492 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 Pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. R1782R) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

CEP290-related disorder Pathogenic:1
The CEP290 c.5344C>T variant is predicted to result in premature protein termination (p.Arg1782*). This variant has been reported in individuals with Leber congenital amaurosis (Coppieters et al. 2010. PubMed ID: 20683928; Bachmann-Gagescu et al. 2015. PubMed ID: 26092869) and Joubert syndrome (Fleming et al. 2017. PubMed ID: 29146704). This variant is reported in 0.0088% of alleles in individuals of African descent in gnomAD. Nonsense variants in CEP290 are expected to be pathogenic. This variant is interpreted as pathogenic. -
Meckel-Gruber syndrome;C0431399:Joubert syndrome;C0687120:Nephronophthisis Pathogenic:1
This sequence change creates a premature translational stop signal (p.Arg1782*) 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 (rs575767207, gnomAD 0.009%). This premature translational stop signal has been observed in individuals with CEP290-related conditions (PMID: 20683928, 29146704). ClinVar contains an entry for this variant (Variation ID: 217636). For these reasons, this variant has been classified as Pathogenic. -
not provided Pathogenic:1
The R1782X nonsense variant in the CEP290 gene has been reported previously in association with Leber congenital amaurosis (LCA) (Coppieters et al., 2010). This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. -

Meckel syndrome, type 4 Pathogenic:1
The CEP290 variant c.5344C>T p.(Arg1782*) creates a premature stop codon. According to HGMD Professional 2022.4, this variant has previously been described as disease causing by Coppieters et al., 2010 (PMID: 20683928), Xiong et al., 2015 (PMID: 25525159), Bachmann-Gagescu et al., 2015 (PMID: 26092869). Additionally, this variant was previously detected in our in-house IAH database in a fetus overlapping phenotype. It is classified as pathogenic (class 1) according to the recommendations of ACMG/AMP/ClinGen SVI guidelines. -
