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), LabcorpNov 27, 2019For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in CPLANE1 are known to be pathogenic (PMID: 22425360, 24178751). This variant has been observed in an individual within a cohort of individuals who have clinical findings of Joubert syndrome or have a sibling with Joubert syndrome (PMID: 26092869). ClinVar contains an entry for this variant (Variation ID: 217578). This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Leu171Serfs*11) in the CPLANE1 gene. It is expected to result in an absent or disrupted protein product. -
