| Clinics and Pathology |
| Disease | ANLL |
| Phenotype / cell stem origin | M5/M4; ALL at times, therapy related cases |
| Epidemiology | from infants to adults |
| Prognosis | poor |
| Cytogenetics |
| Cytogenetics Morphological | A high diversity of reported breakpoints on chromosome 10, from 10p11 to 10p15: remains to be fully studiedL |
| Additional anomalies | inv(11)(q13q23) is frequently acompanying the t(10;11); this is likely to be related to the transcription directions of the two genes |
| Genes involved and Proteins |
| Gene Name | AF10 |
| Location | 10p12 |
| Dna / Rna | 5' telomeric --> 3' centromeric orientation |
| Protein | contains 3 Zn fingezrs and a leucine zipper; nuclear localisation; transcription factor |
| Gene Name | MLL |
| Location | 11q23 |
| Dna / Rna | 21 exons, spanning over 100 kb; 13-15 kb mRNA |
| Protein | 431 kDa; contains two DNA binding motifs (a AT hook, and Zinc fingers), a DNA methyl transferase motif, a bromodomain; transcriptional regulatory factor; nuclear localisation |
| Result of the chromosomal anomaly |
| Description | 5' MLL - 3' AF10; variable breakpoints on both chromosomes; the fusion transcript on chromosome 11 is the crucial one; MLL and AF10 are in opposite transcriptional directions, wich may be cause of the complexity of the translocation |
| Description | N-term AT hook and DNA methyltransferase from MLL fused to the leucine zipper C-term of AF10 |
| Expression Localisation | nuclear localisation |

| To be noted |
| having a glance at 11q23 rearrangements, gives an overview of related diseases |
| Bibliography |
| The t(10;11) translocation in acute myeloid leukemia (M5) consistently fuses the leucine zipper motif of AF10 onto the HRX gene. |
