Variant summary
Our verdict is Pathogenic. The variant received 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_001194998.2(CEP152):c.2959C>T(p.Arg987*) variant causes a stop gained change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000108 in 1,576,606 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. R987R) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 56). This premature translational stop signal has been observed in individual(s) with CEP152-related conditions (PMID: 20598275). This variant is present in population databases (rs267606718, gnomAD 0.004%). This sequence change creates a premature translational stop signal (p.Arg987*) in the CEP152 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CEP152 are known to be pathogenic (PMID: 21131973). -
