Organs

Bone Marrow; Peripheral blood

Specimen Requirements

Minimum of 3 mL whole blood in a purple (EDTA) or pink top tube (EDTA); minimum of 1 mL of bone marrow aspirate in a purple, pink, or green (heparin) top tube.

Diagnostic Utility

CEBPA biallelic mutations have been used as indicator for risk stratification on prognosis for cytogenetically normal acute myeloid leukemia (CN-AML).

Clinical Significance

This test detects deletion or duplication mutations in the CCAAT/enhancer-binding protein alpha (CEBPA) gene on chromosome 19 (q13.11) in patients with clinical symptoms associated with AML. AML with mutated CEBPA gene is a diagnostic category in the current WHO classification of hematopoietic neoplasms. CEBPA mutation on both alleles (so-called double mutation status) is considered a good prognostic feature in adults with newly diagnosed AML whom have a normal karyotype or do not contain an alternate diagnostic genetic abnormality.
