Purpose of review: The mutational landscape of acute myeloid leukemia (AML) has revised diagnostic, prognostic, and therapeutic schemata over the past decade. Recurrently mutated AML genes have functional consequences beyond typical oncogene-driven growth and loss of tumor suppresser function.
Recent findings: Large-scale genomic sequencing efforts have mapped the complexity of AML and trials of mutation-based targeted therapy has led to several FDA-approved drugs for mutant-specific AML. However, many recurrent mutations have been identified across a spectrum from clonal hematopoiesis to myelodysplasia to overt AML, such as effectors of DNA methylation, chromatin modifiers, and spliceosomal machinery. The functional effects of these mutations are the basis for substantial discovery.
Summary: Understanding the molecular and pathophysiologic functions of key genes that exert leukemogenic potential is essential towards translating these findings into better treatment for AML.
