chr5-37206339-C-A

Variant summary

Our verdict is Pathogenic. Variant got 12 ACMG points: 12P and 0B. PVS1 PM2 PP5_Moderate

The NM_001384732.1(CPLANE1):c.3007G>T(p.Glu1003Ter) variant causes a stop gained change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Synonymous variant affecting the same amino acid position (i.e. E1003E) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

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 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 5-37206339-C-A is Pathogenic according to our data. Variant chr5-37206339-C-A is described in ClinVar as [Pathogenic]. Clinvar id is 217581.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr5-37206339-C-A is described in Lovd as [Pathogenic].
