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]

Ambry Genetics

Apr 25, 2022

The c.104A>G (p.N35S) alteration is located in exon 1 (coding exon 1) of the CAMSAP2 gene. This alteration results from a A to G substitution at nucleotide position 104, causing the asparagine (N) at amino acid position 35 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
