ICD-Morpho 9861/3 AML with mutated NPM1; AML with mutated CEBPA; Acute myeloid leukaemia, NOS
Atlas_Id 2134

Clinics and Pathology

Disease Acute myeloid leukaemia
Epidemiology Only one case to date, a 42 year old male patient (Reader et al., 2007).
Evolution The patient achieved complete remission for 11 months, but relapsed and died 3 months after.


Cytogenetics Morphological Sole anomaly; as a matter of fact, the karyotype appeared normal, with a doubt on one chromosome 17: Cryptic translocation.

Genes involved and Proteins

Gene NameNUP98 (nucleoporin 98 kDa)
Location 11p15.4
Protein Nucleoporin: associated with the nuclear pore complex. Role in nucleocytoplasmic transport processes.
Gene NamePHF23 (PHD finger protein 23)
Location 17p13.1
Protein Recently discovered gene, which possess a plant homeodomain. Possible effect on chromatin structure and transcriptional regulation.

Result of the chromosomal anomaly

Hybrid gene
Transcript NUP98 exon 13 fused in frame to PHF23 exon 4.
Fusion Protein
Description NH2-term NUP98 including the Phe-Gly repeats, the GLEB domain fused to the coiled-coil domain and the plant homeodomain of PHF23 C-term.

To be noted

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