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]

Variant classified as Pathogenic and reported on 01-22-2018 by HNL Genomics Connective Tissue Gene Tests. Assertions are reported exactly as they appear on the patient provided laboratory report. GenomeConnect does not attempt to reinterpret the variant. The IDDRC-CTSA National Brain Gene Registry (BGR) is a study funded by the U.S. National Center for Advancing Translational Sciences (NCATS) and includes 13 Intellectual and Developmental Disability Research Center (IDDRC) institutions. The study is led by Principal Investigator Dr. Philip Payne from Washington University. The BGR is a data commons of gene variants paired with subject clinical information. This database helps scientists learn more about genetic changes and their impact on the brain and behavior. Participation in the Brain Gene Registry requires participation in GenomeConnect. More information about the Brain Gene Registry can be found on the study website - https://braingeneregistry.wustl.edu/. -

Significance: Likely pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on CPLANE1 protein function. ClinVar contains an entry for this variant (Variation ID: 217589). This missense change has been observed in individual(s) with Joubert syndrome (PMID: 26092869). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 871 of the CPLANE1 protein (p.Arg871Cys). -

Significance: Likely pathogenic

Review Status: no assertion criteria provided

Collection Method: clinical testing

The CPLANE1 c.2611C>T variant is predicted to result in the amino acid substitution p.Arg871Cys. This variant was reported in an individual with Joubert syndrome (Bachmann-Gagescu et al. 2015. PubMed ID: 26092869). This variant is reported in 0.016% of alleles in individuals of Ashkenazi Jewish descent in gnomAD. This variant is interpreted as likely pathogenic. -
