This sequence change creates a premature translational stop signal (p.Leu2606*) in the CPLANE1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CPLANE1 are known to be pathogenic (PMID: 24178751, 26092869). This variant is present in population databases (rs749523755, gnomAD 0.005%). This premature translational stop signal has been observed in individuals with Joubert syndrome and oral-facial-digital syndrome, type VI (PMID: 25407461, 26092869). ClinVar contains an entry for this variant (Variation ID: 217575). For these reasons, this variant has been classified as Pathogenic. -
