These samples were in the same transcript cluster as undetectable-BCR-ABL transcript (Cluster-II-sub-cluster-II); in the CNV-based cluster, samples 2 and 4 were grouped in the higher CNV group (undetectable/<20% BCR-ABL transcript), and CML-10 was grouped in the CNV group with undetectable BCR-ABL transcript levels, new cases or un-detected BCR-ABL (Table 3). Here, ABL1 is linked to chronic myelogenous leukemia, BCR-ABL1 positive.
