FLI1（Fli-1 proto-oncogene， ETS transcription factor），癌症关联基因，基因ID：2313，该基因编码一个包含ets DNA结合域的转录因子。该基因可以与位于染色体22上的尤因肉瘤基因进行T（11；22）（q24；q12）易位，从而导致大多数尤因肉瘤病例中存在融合基因。一个急性淋巴母细胞白血病相关的T（4；11）（q21；q23）易位涉及这个基因也被确认。选择性剪接导致多个转录变体。This gene encodes a transcription factor containing an ETS DNA-binding domain. The gene can undergo a t(11;22)(q24;q12) translocation with the Ewing sarcoma gene on chromosome 22， which results in a fusion gene that is present in the majority of Ewing sarcoma cases. An acute lymphoblastic leukemia-associated t(4;11)(q21;q23) translocation involving this gene has also been identified. Alternative splicing results in multiple transcript variants.关联癌症：尤因肉瘤。
