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]

Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	May 15, 2019	Not observed at a significant frequency in large population cohorts (Lek et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Oct 11, 2020	In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. 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. This variant has not been reported in the literature in individuals with CPLANE1-related conditions. ClinVar contains an entry for this variant (Variation ID: 522592). This variant is not present in population databases (ExAC no frequency). This sequence change replaces isoleucine with threonine at codon 1426 of the CPLANE1 protein (p.Ile1426Thr). The isoleucine residue is moderately conserved and there is a moderate physicochemical difference between isoleucine and threonine. -
