CNV analysis was performed for five genes; Arginosuccinate synthase 1 (ASS1), Exosome component 2 (EXOSC2), Far upstream binding protein 3 (FUBP3), Formin binding protein 1 (FNBP1), and SWI/SNF Related Matrix Associated Actin Dependent Regulator of Chromatin (SMARCB1) (Table S2) in CML and control samples using RT–PCR. This evidence concerns the gene ASS1 and chronic myelogenous leukemia, BCR-ABL1 positive.
