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 GeneticsDec 20, 2021The c.272G>A (p.S91N) alteration is located in exon 2 (coding exon 2) of the CAMSAP2 gene. This alteration results from a G to A substitution at nucleotide position 272, causing the serine (S) at amino acid position 91 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
