Summary
Brief summary (as posted)
The main task of this study includes analyses of the BCR-ABL1 (breakpoint cluster region/Abelson) gene and mutations in the BCR-ABL1 tyrosine kinase domain within flow-sorted stem cells from the bone marrow and/or peripheral blood specimens. To assess the germline configuration of the patient, DNA from fingernail clippings will be investigated.

- measure
- Leukemic stem/progenitor cells defined by a specific marker profile will be isolated from BM/PB by flow sorting. Screening for and monitoring of BCR-ABL1 TKD mutant subclones at the cDNA/DNA levels within the 1st year of TKI therapy will be done by NGS.
