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]

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces alanine with glutamic acid at codon 1200 of the CPLANE1 protein (p.Ala1200Glu). The alanine residue is moderately conserved and there is a moderate physicochemical difference between alanine and glutamic acid. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individual(s) with CPLANE1-related conditions (PMID: 29605658). It has also been observed to segregate with disease in related individuals. 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) performed at Invitae indicates that this missense variant is expected to disrupt CPLANE1 protein function. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. This variant disrupts the p.Ala1200 amino acid residue in CPLANE1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 24091540, 25407461, 27081551, 29605658). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -
