| Transcription | 1.8 kb mRNA; coding sequence CDS 401... 673 |
| Protein |
| Description | 90 amino acids; 9 kDa |
| Expression | detected in various tissues (small intestine, colon, thymus mainly), but not in (normal) mature blood cells; expressed in all leukemic cell lines tested |

| Note | |
| Entity | t(1;11) (q21;q23)/AML --> MLL - AF1q |
| Disease | AML |
| Prognosis | yet unknown |
| Hybrid/Mutated Gene | breakpoints: between exons 6 and 7 in MLL and within the 5' untranslated region in AF1q |
| Abnormal Protein | N-term -- AT hook and DNA methyltransferase from MLL fused to the entire AF1q on the der(11); the reciprocal on der(1) is out of frame |
