| Note | the description opf this rare entity is arduous, since cases without molecular studies can be confused with cases of t(10;11)(p12;q23) |

| Clinics and Pathology |
| Disease | a mainly T-cell ALL; at times AML and/or AML with T-cell markers, or B-cell ALL common progenitor may be involved; FAB: L1/L2 |
| Phenotype / cell stem origin | a myelomonocytic/T- cell |
| Epidemiology | < 1% of ALL; about 5 % of T-ALL; sex ratio: 9M/5F (from 14 cases herein reviewed) |
| Clinics | organomegaly; no CNS involvement; blood data: high WBC (range 20-170 X 109/l) |
| Prognosis | median survival: 22 mths in this review; range: 0-33+ mths, n=11 (but we are to be cautious: cases ascertained by molecular studies are needed before true prognostic ascertainment) |
| Cytogenetics |
| Cytogenetics Molecular | investigations are required |
| Additional anomalies | most often (11/15 cases) present; del(5q), +8, and +19 already recurrent |
| Genes involved and Proteins |
| Gene Name | MLLT10 (myeloid/lymphoid or mixed-lineage leukemia (trithorax homolog, Drosophila); translocated to, 10) |
| Location | 10p12.31 |
| Dna / Rna | 5' telomeric --> 3' centromeric orientation |
| Protein | contains 3 Zn fingezrs and a leucine zipper; nuclear localisation; transcription factor |
| Gene Name | PICALM (clathrin assembly lymphoid myeloid leukemia gene) |
| Location | 11q14.2 |
| Protein | role in the integration of different signals; |
| Result of the chromosomal anomaly |
| Transcript | both 5' CALM - 3' AF10 and 5' AF10 - 3' CALM are expressed |
| Description | 1- a 1595 amino acids protein with N-term and most of CALM (except the last 4 amino acids!) fused to most of AF10 from amino acid 81 (excluding the N-term zinc finger of AF10) C-term; 2- and a small 84 amino acids protein with N-term zinc finger from AF10 fused to the very C-term end of CALM |
| Oncogenesis | it is not known which of the 2 fusion protein has the critical role |
