Confidently keep an eye on CML

What is CML?

Chronic myeloid leukemia (CML) is a type of blood cancer that’s caused by a genomic alteration in myeloid blood-forming cells in the bone marrow. This leads to an overproduction of CML blood cells, and an eventual reduction in other healthy blood cells.

CML is also known as chronic myelogenous leukemia, chronic granulocytic leukemia or chronic myelocytic leukemia, and accounts for 15–20% of all adult leukemia cases.* It is classified by the WHO as a myeloproliferative neoplasm (MPN).**

What causes CML?

More than 95% of CML cases have an abnormal translocation of chromosomes 9 and 22 called the Philadelphia (Ph) chromosome, resulting in the BCR::ABL1 fusion gene. These CML cases are often referred to as Philadelphia chromosome positive (Ph+).*** 

The BCR::ABL1 gene instructs the abnormal blood cell —inside which the translocation occurred— to overproduce a protein called tyrosine kinase. The elevated tyrosine kinase activity leads to the development of CML cells.

For effective CML patient care and management, BCR::ABL1 Mbcr levels need to be measured routinely.

It's now easier than ever to monitor CML

Quantitation of BCR::ABL1 Mbcr transcripts by qPCR is essential to disease monitoring in CML patients.

With the International Scale (IS) standardization of BCR::ABL1 measurements, monitoring CML is now straightforward.

You can be sure you’re consistently interpreting clinical research data and using similar clinical decision values as other oncologist-hematologists.****

Real-world lab experiences

In line with established HUGO Gene Nomenclature Committee (HGNC) recommendations for the fusion gene nomenclature (Bruford EA, et al. Leukemia. 2021,, we are implementing use of italics and double colon (::) for fusion genes designation (e.g. BCR::ABL1). However historical nomenclature (e.g. BCR-ABL1) may persist in our materials
