Advancements in next-generation sequencing (NGS) have increased our understanding on genomic and epigenomic landscapes in AML [5, 6], and therefore, precision therapy has become possible in AML treatment, multiple studies of targeted drugs (such as IDH inhibitors, FLT3 inhibitors and BCL-2 inhibitors, etc.)are ongoing [7–12]. The gene discussed is BCL2; the disease is acute myeloid leukemia.
