Our verdict is Likely benign. Variant got -4 ACMG points: 0P and 4B. BS2
The NM_001365631.1(CLASP2):c.4208A>G(p.Asp1403Gly) variant causes a missense change. The variant allele was found at a frequency of 0.0000335 in 1,613,750 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Uncertain significance (★).
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.

Review Status: criteria provided, single submitter
Collection Method: clinical testing
The c.4235A>G (p.D1412G) alteration is located in exon 38 (coding exon 38) of the CLASP2 gene. This alteration results from a A to G substitution at nucleotide position 4235, causing the aspartic acid (D) at amino acid position 1412 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
