| Clinics and Pathology |
| Disease | described in only 6 cases; acute lymphoblastic leukemia (ALL), acute non lymphocytic leukemia (ANLL) and chronic myeloid leukemia (CML) |
| Prognosis | numbers small, but one CML case had allogeneic BMT and is in complete remission, the remaining cases had rapid disease progression and died of shortly after diagnosis |
| Cytogenetics |
| Cytogenetics Morphological | t(9;12)(q34;p13), cryptic at the cytogenetic level |
| Variants | t(9;12;14)(q34;p13;q22) and complex insertions of ETV6 into ABL |
| Genes involved and Proteins |
| Gene Name | ABL |
| Location | 9q34 |
| Dna / Rna | ETV6 is fused to exon 2 of ABL in the three cases described |
| Protein | tyrosine kinase, localized primarily to the nucleus |
| Gene Name | ETV6 |
| Location | 12p13 |
| Dna / Rna | 9 exons; alternate splicing |
| Protein | contains Helix-Loop-Helix (HLH) at N-terminal end and ETS DNA binding domain at C-terminal end; wide expression; nuclear localization; ETS- related transcription factor |
| Result of the chromosomal anomaly |
| Description | 5 ETV6 - 3 ABL; two different fusion breakpoints have been described; ETV6 exon 4 fused in frame to ABL exon 2 (Type A) and ETV6 exon 5 fused in frame to ABL exon 2 (Type B); ETV6 maintains the HLH domain and ABL the tyrosine kinase domain |
| Description | a 155 kDa protein in Type A, 180 kDa protein in Type B; has elevated tyrosine kinase activity, localized in the cytoplasm and co-localizes with the actin filaments of the cells |
