Genetic Variant CPLANE1:p.Asp1287Asn (chr5-37187795-C-T) – ACMG Classification: Uncertain_significance (4 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM2PM5

The NM_001384732.1(CPLANE1):c.3859G>A(p.Asp1287Asn) variant causes a missense change. The variant allele was found at a frequency of 0.00000657 in 152,284 control chromosomes in the GnomAD database, with no homozygous occurrence. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D1287H) has been classified as Likely pathogenic.

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]
