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.4247A>T (p.N1416I) alteration is located in exon 38 (coding exon 38) of the CLASP2 gene. This alteration results from a A to T substitution at nucleotide position 4247, causing the asparagine (N) at amino acid position 1416 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
