The required number of banked samples could not be met due to limited availability. There is no realistic possibility to complete the study succesfully.

This clinical study will demonstrate the accuracy of the chromosomal aberration and gene mutation markers of the AMLProfiler molecular diagnostic assay and generate clinical performance data to support a Pre-Market Approval (PMA) submission to the Food and Drug Administration for in vitro diagnostic use within the United States of America.

The objective is to demonstrate the positive and negative percent agreement of each marker by comparing AMLProfiler results from multiple clinical participating sites with data generated using a laboratory developed bi-directional sequencing method generated at the molecular diagnostic reference lab.

The AMLProfiler assay is a qualitative in vitro diagnostic test for the detection of AML or APL specific chromosomal aberrations (specific recurrent translocations and inversions), as well as expression of specific genetic markers in RNA extracted from bone marrow aspirates of patients with Acute Myeloid Leukemia.

Inclusion Criteria:

1. Subjects with a cytopathologically confirmed diagnosis of AML subjects with refractory anemia with excess of blasts (RAEB) according to the WHO 2008 classification
2. ≥ 18 years
3. Written informed consent

Exclusion Criteria:

1. Subjects without a cytopathologically confirmed diagnosis of AML subjects with refractory anemia with excess of blasts (RAEB) according to the WHO 2008 classification
2. < 18 years
3. Without written informed consent

Bone marrow samples will be used in the study only from AML,APL or RAEB subjects. Written informed consent by subjects will be obtained for use of their bone marrow samples in this study. Each site will follow their own bone marrow aspiration procedure.
