The recent advent of next-generation sequencing (NGS) has greatly accelerated identification of gene mutations in myeloid malignancies at unprecedented speed that will soon outpace their functional validation by conventional laboratory techniques and animal models. A high-throughput whole-organism model is useful for the functional validation of new mutations. We recently reported the use of zebrafish to evaluate the hematopoietic function of isocitrate dehydrogenase 1 (IDH1) and the effects of expressing human IDH1-R132H that is frequently identified in human acute myeloid leukemia (AML), in myelopoiesis, with a view to develop zebrafish as a model of AML. Here, we use IDH1 as an example to describe a comprehensive approach to evaluate hematopoietic gene function and the effects of mutations using zebrafish as a model.
