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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 27, 2023The c.635G>C (p.G212A) alteration is located in exon 4 (coding exon 4) of the CAMSAP2 gene. This alteration results from a G to C substitution at nucleotide position 635, causing the glycine (G) at amino acid position 212 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
