...the VAFs of ASXL1G646Wfs*12 mutation significantly-decreased when in the temporarily response (p = 0.05), while significantly-increased when the secondary resistance occurred (p = 0.015, Figure 4A) in the secondary resistant cohort....ASXL1G646Wfs*12, RUNX1, IKZF1, SETBP1 and PHF6 mutations are the key drivers of resistance to 3G-TKI therapy in CML.
