Tyrosine Kinase Domain Mutation Analysis
|Category||Specialist Integrated Haematological Malignancy Diagnostic Service (SIHMDS) >> Molecular Pathology|
Mutations in the tyrosine kinase domain of BCR-ABL are the most common cause of resistance to the tyrosine kinase inhibitors (TKI) in CML patients. Therefore, early detection of these mutations will guide clinicians to a more appropriate course of treatment. Sanger sequencing can detect a range of mutations within the TK domain to the level of approximately 20%
BCR-ABL1 positive patients that are relapsing or not responding to treatment.
