Abstract
T-cell acute lymphoblastic leukemia (T-ALL) is the result of multiple oncogenic insults of thymocytes. Recently, new ABL1 fusion genes have been identified that provide proliferation and survival advantage to lymphoblasts. These are the NUP214-ABL1 fusion gene, on amplified episomes, the unique case of EML1-ABL1 fusion due to a cryptic t(9;14)(q34;q32) and the seldom reported BCR-ABL1 and ETV6-ABL1 chimeric genes. The most frequent and strictly associated with T-ALL is the NUP214-ABL1 fusion identified in 6% of cases, in both children and adults. Patients present with classical T-ALL features. Cytogenetically, the fusion is cryptic but seen by FISH on amplified episomes or more rarely as a small hsr. The ABL1 fusion is a late event associated with other genetic alterations like NOTCH1 activating mutation, deletion of CDKN2A locus, and ectopic expression of TLX1 or TLX3. The mechanism of activation of the NUP214-ABL1 protein is unique and requires localization at the nucleopore complex and interaction with other nuclear pore proteins for crossphosphorylation and constitutive kinase activity. The ABL1 fusion proteins are sensitive to tyrosine kinase inhibitors, which can be included in future treatment strategy.

Abstract
Episomes with the NUP214-ABL1 fusion gene have been observed in 6% of T-ALL. In this multicentric study we collected 27 cases of NUP214-ABL1-positive T-ALL. Median age was 15 years with male predominance. Outcome was poor in 12 patients. An associated abnormality involving TLX1 or TLX3 was found in all investigated cases. Fluorescent in situ hybridization revealed a heterogeneous pattern of NUP214-ABL1 amplification. Multiple episomes carrying the fusion were detected in 24 patients. Episomes were observed in a significant number of nuclei in 18 cases, but in only 1-5% of nuclei in 6. In addition, intrachromosomal amplification (small hsr) was identified either as the only change or in association with episomes in four cases and two T-ALL cell lines (PEER and ALL-SIL). One case showed insertion of apparently non-amplified NUP214-ABL1 sequences at 14q12. The amplified sequences were analyzed using array-based CGH.These findings confirm that the NUP214-ABL1 gene requires amplification for oncogenicity; it is part of a multistep process of leukemogenesis; and it can be a late event present only in subpopulations. Data also provide in vivo evidence for a model of episome formation, amplification and optional reintegration into the genome. Implications for the use of kinase inhibitors are discussed.
