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.1894T>G (p.Y632D) alteration is located in exon 11 (coding exon 11) of the CAMSAP2 gene. This alteration results from a T to G substitution at nucleotide position 1894, causing the tyrosine (Y) at amino acid position 632 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
