Genes affected
CPLANE1 (HGNC:25801): (ciliogenesis and planar polarity effector complex subunit 1) The protein encoded by this gene has putative coiled-coil domains and may be a transmembrane protein. Defects in this gene are a cause of Joubert syndrome (JBTS). [provided by RefSeq, May 2012]

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 13, 2023This sequence change creates a premature translational stop signal (p.Gln793*) 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 (rs776886962, gnomAD 0.005%). This premature translational stop signal has been observed in individual(s) with orofaciodigital syndrome (PMID: 24178751). ClinVar contains an entry for this variant (Variation ID: 217583). 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. -
