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
ICD-Morpho 9989/3 Myelodysplastic syndrome, unclassifiable
Atlas_Id 1174

Clinics and Pathology

Disease myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML)
Phenotype / cell stem origin 1 case of refractory anemia with excess of blastsin transformation (RAEB-t), 1 MDS evolving towards a M4-AML, 2 M2-AML, and 1 AML not otherwise specified
Epidemiology 5 cases to date; 3M/2F, aged 58 yr (median, range: 31-75)

Cytogenetics

Cytogenetics Morphological sole anomaly in 2 cases, complex karyotypes in 2 other cases.

Genes involved and Proteins

Note The gene in 5q13 is yet unknown, and, because cryptic t(12;21) ETV6 /AML1 are not rare, it is therefore uncertain whether this translocation involve a new AML1 partner
Gene NameRUNX1 (runt-related transcription factor 1 (acute myeloid leukemia 1; aml1 oncogene))
Location 21q22.12
Dna / Rna transcription is from telomere to centromere
Protein contains a Runt domain and, in the C-term, a transactivation domain; forms heterodimers; widely expressed; nuclear localisation; transcription factor (activator) for various hematopoietic-specific genes

To be noted

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