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]

ACMG classification

Verdict is Benign. Variant got -11 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.78).
• BP6: Variant 5-37224605-T-C is Benign according to our data. Variant chr5-37224605-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 261668.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr5-37224605-T-C is described in Lovd as [Benign].
• BP7: Synonymous conserved (PhyloP=-0.746 with no splicing effect.
