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]

The c.1067C>T (p.A356V) alteration is located in exon 8 (coding exon 8) of the CAMSAP2 gene. This alteration results from a C to T substitution at nucleotide position 1067, causing the alanine (A) at amino acid position 356 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
