| Identity |
| ICD-Topo | C420,C421,C424 BLOOD, BONE MARROW, & HEMATOPOIETIC SYS |
| ICD-Morpho | 9807/3 Mixed phenotype acute leukaemia with t(v;11q23); MLL rearranged |
| ICD-Morpho | 9811/3 B lymphoblastic leukaemia/lymphoma, NOS |
| ICD-Morpho | 9813/3 B lymphoblastic leukaemia/lymphoma with t(v;11q23); MLL rearranged |
| Atlas_Id | 1167 |
| Clinics and Pathology |
| Disease | acute lymphoblastic leukemia (ALL) and ALL evolving towards a M4- acute non lymphocytic leykemia (AML) |
| Phenotype / cell stem origin | CD19+ |
| Epidemiology | poorly defined: only 2 cases to date |
| Clinics | a girl aged 4 mths, who entered complete remission, relapsed and died 20 mths after diagnosis, and a 3 mth old boy who had a 18 mths remission, developped relapses and died. |
| Prognosis | yet unknown, likely to be poor |
| Cytogenetics |
| Cytogenetics Morphological | the chromosomal rearrangement may be hidden if only a small portion of chromosome 11 (with MLL) is transferred into chromosome 5 (in the vicinity of AF5Q31) |
| Cytogenetics Molecular | the use of MLL probes can uncover the anomaly |
| Additional anomalies | i(17q) in one case, and a complex karyotype in the other case |
| Variants | a few cases of t(5;11)(q31;q23) have been described, but it is unknown if they involve the same genes |
| Genes involved and Proteins |
| Gene Name | AFF4 (ALL1 fused gene from chromosome 5q31) |
| Location | 5q31.1 |
| Protein | present homologies with AF4 |
| Gene Name | KMT2A (myeloid/lymphoid or mixed lineage leukemia) |
| Location | 11q23.3 |
| Dna / Rna | 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' AF5q31 |
| 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. |
