D = diagnostic significance; P = prognostic significance; T = therapeutic significance. Classification of levels of evidence: Level 1 = WHO classification or professional practice guidelines; Level 2 = well-powered studies with consensus from experts in the field; Level 3 = multiple small studies without any contradicting data; Level 4 = individual small studies, case reports, preclinical studies.

Abrreviations: CMA = chromosomal microarray; CNA = copy number aberration; CN-LOH = copy-neutral loss-of-heterozygosity; AML = acute myeloid leukemia; NK-AML = normal karyotype AML; pAML = primary AML; and sAML = secondary AML.

The * indicates CNAs and CN-LOH regions that are predominantly seen in AML.
