The ETS variant gene 6 (ETV6) gene is located at 12p13, and is frequently involved in translocations in various human neoplasms, resulting in the expression of fusion proteins consisting of the amino-terminal part of ETV6 and unrelated transcription factors or protein tyrosine kinases. Leukemia with t(1;12)(q21;p13) was previously described in a 5-year-old boy with acute myeloblastic leukemia (AML-M2) who exhibited a novel ETV6-aryl hydrocarbon receptor nuclear translocator (ARNT) fusion protein. We herein report the case of a 2-year-old boy with T-cell lymphoblastic leukemia (T-ALL) harboring t(1;12)(q21;p13). Fluorescence in situ hybridization (FISH) with a ETV6 dual-color DNA probe revealed that the split signals of the ETV6 gene in 96.7% of bone marrow cells, indicating rearrangement of the ETV6 gene. Therefore, we performed a FISH analysis with bacterial artificial chromosome (BAC) probes containing the ARNT, BCL9, and MLLT11 genes located at 1q21, and these results indicated that the ARNT gene might be involved in the t(1;12)(q21;p13). Reverse transcriptase-polymerase chain reaction analysis disclosed the existence of a ETV6-ARNT fusion gene. To our knowledge, the current report is novel in its report of the ETV6-ARNT fusion in childhood T-ALL. The ETV6-ARNT fusion is associated not only with AML but also with T-ALL.
