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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 11, 2023The c.3710C>T (p.S1237F) alteration is located in exon 35 (coding exon 35) of the CLASP2 gene. This alteration results from a C to T substitution at nucleotide position 3710, causing the serine (S) at amino acid position 1237 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
