One thing that does stand out to me is that there are no actual copies of BCR-Abl shown as detected on the report. There are 10693 copies of the Abelson control gene, and unless my maths is failing me terribly, 0 over 10693 is 0, not 0.01 (or 0.006).

If positive, the quantitative level is reported as the normalized ratio of BCR/ABL1 (p210) to endogenous ABL1 mRNA with conversion to a percentage referenced to the international scale (IS), on which 0.1% BCR/ABL1:ABL1 (also represented on a log scale as Molecular Response 3, or MR3) is designated as a major molecular response (MMR) threshold.

What degree of increase in BCR-ABL1 transcript suggests secondary resistance? Therapeutic response to initial treatment is indicated by a drop in the BCR-ABL1 level. A subsequent 5-to 10-fold increase in the % (IS) level suggests developing drug resistance, which is usually due to an ABL1 mutation or clonal evolution. Other indicators of secondary resistance include overt hematologic or cytogenetic relapse and emergence of blast phase. ABL1. (redirected from bcr/abl) ABL1.

The presence of the gene sequence known as BCR-ABL1 confirms the diagnosis of CML and a form of acute lymphoblastic lymphoma (ALL), specifically a type of B-lymphoblastic leukemia/lymphoma. In very rare cases, the abnormal chromosome is linked to cases of acute myeloid leukemia and T-lymphoblastic leukemia/lymphoma.
