Genes affected

CAMSAP1 (HGNC:19946): (calmodulin regulated spectrin associated protein 1) Enables microtubule minus-end binding activity and spectrin binding activity. Involved in several processes, including neuron projection development; regulation of cell morphogenesis; and regulation of microtubule polymerization. Located in microtubule. Colocalizes with microtubule minus-end. [provided by Alliance of Genome Resources, Apr 2022]

The c.3614T>C (p.V1205A) alteration is located in exon 11 (coding exon 11) of the CAMSAP1 gene. This alteration results from a T to C substitution at nucleotide position 3614, causing the valine (V) at amino acid position 1205 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
