摘要
RUNX1/AML1, located on chromosome 21, is a key factor in the generation and maintenance of hematopoietic stem cells and the gene most frequently implicated in human leukemias. Chromosome translocations and point mutations are well-documented genetic alterations in RUNX leukemia (also known as CBF leukemia). In addition, overdosage or overexpression of RUNX1 is suspected to be a third mode of RUNX1 involvement in leukemogenesis. The possibility that this mode might underlie Down syndrome-related leukemias caused by trisomy of chromosome 21 is discussed.
