Genes affected
CLASP1 (HGNC:17088): (cytoplasmic linker associated protein 1) CLASPs, such as CLASP1, are nonmotor microtubule-associated proteins that interact with CLIPs (e.g., CLIP170; MIM 179838). CLASP1 is involved in the regulation of microtubule dynamics at the kinetochore and throughout the spindle (Maiato et al., 2003 [PubMed 12837247]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 12, 2023The c.3712C>T (p.R1238W) alteration is located in exon 35 (coding exon 34) of the CLASP1 gene. This alteration results from a C to T substitution at nucleotide position 3712, causing the arginine (R) at amino acid position 1238 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
