| BTK C481A | chronic lymphocytic leukemia | predicted - resistant | Ibrutinib | Preclinical | Actionable | In a preclinical study, patients with BTK C481 were predicted to have resistance to Imbruvica (ibrutinib) since C481 is in the covalent binding site of the BTK inhibitor and C481A interferes with drug binding (PMID: 24869597). | 24869597 |
