This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 1336 of the CPLANE1 protein (p.Arg1336Trp). This variant is present in population databases (rs367543061, gnomAD 0.004%). This missense change has been observed in individual(s) with Joubert syndrome (PMID: 22425360). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 31219). 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 with a positive predictive value of 95%. For these reasons, this variant has been classified as Pathogenic. -

Variant summary: CPLANE1 c.4006C>T (p.Arg1336Trp) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 2.1e-05 in 280178 control chromosomes. c.4006C>T has been reported in the literature as a compound heterozygous genotype in multiple individuals affected with Joubert Syndrome (example, Srour_2012, Bachmann-Gagescu_2015). These data indicate that the variant is very likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Two clinical diagnostic laboratories, a research program and the Gene Reviews database have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All submitters classified the variant as pathogenic/likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -
