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 Pathogenic. Variant got 16 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PP5: Variant 5-37180085-TCA-T is Pathogenic according to our data. Variant chr5-37180085-TCA-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 445343.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
