Identity

ICD-Topo C420,C421,C424 BLOOD, BONE MARROW, & HEMATOPOIETIC SYS
ICD-Morpho 9861/3 AML with mutated NPM1; AML with mutated CEBPA; Acute myeloid leukaemia, NOS
Atlas_Id 1532

Clinics and Pathology

Disease Acute myeloid leukaemia (AML)
Phenotype / cell stem origin Myeloid leukaemias (Paietta et al., 1988; Scheurlen et al., 1999), if we exclude a case of lymphoplasmacytoid lymphoma (Offit el al., 1995). The translocation is found in M1-AML and M2-AML, with erythroid hyperplasia in the bone marrow and the presence of binucleated and trinucleated red cells in at least 3 of 4 cases (Paietta et al., 1988).
Epidemiology Four cases available, 2 male and 2 female patients, aged 26, 61, 63, and 63.
Prognosis The clinical outcome is poor, with 2 cases not entering into remission and dead within 2 months after diagnosis, and a third patient with partial remission, relapse after 2 months, and death. The fourth patient's outcome is unknown.

Cytogenetics

Additional anomalies Major karyotypic abnormalities (MAKA) in four of four cases, with marker chromosomes in all cases, -3 in two cases, -5, -7, +8, t(10;11)(p13;q13), i(17q), +18 in one case each.

Genes involved and Proteins

Note The genes involved in this translocation are unknown.

To be noted

Additional cases are needed to delineate the epidemiology of this rare entity:
