Genes affected

CLASP2 (HGNC:17078): (cytoplasmic linker associated protein 2) Enables cytoskeletal protein binding activity; dystroglycan binding activity; and protein tyrosine kinase binding activity. Involved in several processes, including microtubule cytoskeleton organization; positive regulation of extracellular matrix organization; and regulation of supramolecular fiber organization. Located in several cellular components, including basal cortex; cortical microtubule plus-end; and ruffle membrane. Colocalizes with focal adhesion; kinetochore; and microtubule cytoskeleton.

The c.3707G>A (p.R1236H) alteration is located in exon 35 (coding exon 35) of the CLASP2 gene. This alteration results from a G to A substitution at nucleotide position 3707, causing the arginine (R) at amino acid position 1236 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
