Genes affected

CAMSAP2 (HGNC:29188): (calmodulin regulated spectrin associated protein family member 2) Enables microtubule minus-end binding activity. Involved in several processes, including axon development; regulation of dendrite development; and regulation of organelle organization. Located in cytosol and microtubule end. Colocalizes with Golgi apparatus; centrosome; and microtubule minus-end. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Likely_benign. The variant received -6 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.24541956).
• BS2: High AC in GnomAdExome4 at 65 AD gene.
