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]

This sequence change creates a premature translational stop signal (p.Arg2660*) 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 (rs147416429, gnomAD 0.01%). This premature translational stop signal has been observed in individual(s) with Joubert syndrome (PMID: 22693042, 26092869, 33176815). This variant is also known as C5ORF42 p.R2660X. ClinVar contains an entry for this variant (Variation ID: 217566). For these reasons, this variant has been classified as Pathogenic. -
