| Clinics and Pathology |
| Disease | treatment related acute myeloid leukemia (t-AML) so far |
| Epidemiology | only 1 case available |
| Clinics | a 41 yr old female patient with a previous history of non Hodgkin lymphoma treated withtopoisomerase II inhibitors 3 yrs earlier; she developped a M5a t-AML and died 10 days after diagnosis |
| Cytogenetics |
| Additional anomalies | a complex karyotype was found in the only available case, with +8 and other anomalies. |
| Genes involved and Proteins |
| Gene Name | LPP (lipoma preferred partner) |
| Location | 3q28 |
| Protein | LPP is a member of the LIM protein gene family, containing a leucin-zipper motif in its amino-terminal region and three LIM domains in its carboxy-terminal region |
| Gene Name | KMT2A (myeloid/lymphoid or mixed lineage leukemia) |
| Location | 11q23.3 |
| Protein | contains two DNA binding motifs (a AT hook, and Zinc fingers), a DNA methyl transferase motif, a bromodomain; transcriptional regulatory factor involved in maintenance of Hox gene expression |
| Result of the chromosomal anomaly |
| Description | 5' MLL including the 8 first exons fused to the 3 last 3' exons (exons 9 to 11) of LPP. |
| Transcript | the reciprocal 5'MLPP-3'MLL is also transcribed |
| Description | N-term AT hook and DNA methyltransferase from MLL fused to the 2 last C-term LIM domains of LPP |
| To be noted |
| Additional cases are needed to delineate the epidemiology of this rare entity: you are welcome to submit a paper to our new Case Report section. |
