The frequency of ''RUNX1'' mutations is between 5-18% of all AML patients tested [3]. The most common chromosomal translocation is t(8;21)(q22;q22)resulting in RUNX1-RUNX1T1 fusion in ''de novo'' AML, at approximately 7% [2,6]. This translocation confers a favorable prognosis in AML and other neoplasms [2,5,6]. Another ''RUNX1'' alteration is the t(3;21)(q26;q22), in which the RUNT domain of ''RUNX1'' is fused to the entire ''EVI1'' gene. This translocation is rarely found in patients diagnosed with ''de novo'' AML and is more common in those with therapy-related myelodysplastic syndrome (MDS)/AML [9]. Other mutations in ''RUNX1'' include deletions, missense, splicing, frameshift, and nonsense alterations (mostly loss-of-function or decreased function), and occur at a frequency of approximately 10% in AML patients [6]. These mutations are mechanistically distinct from the chromosomal translocations and confer a worse prognosis [2,5,6].

iAMP21 is an intrachromosomal amplification of chromosome 21, which includes the genes ''RUNX1'' and ''miR-802'' among others. This amplification occurs in about 1.5-2% of all Acute Lymphocytic Leukemia cases tested and is associated with poor prognostication [5].

The most common chromosomal translocation is t(12;21)(p13;q22) resulting in ETV6-RUNX1 fusion in B-cell acute lymphocytic leukemia (B-ALL) [2]. This translocation occurs in 25% of Pediatric B-ALL but only 2% of Adult B-ALL [5, 6], and confers a favorable prognosis in B-ALL and other neoplasms [2,5,6]. iAMP21 is an intrachromosomal amplification of chromosome 21 which includes the genes ''RUNX1'' and ''miR-802'' among others.
