ＥＷＳ基因来自导致Ｅｗｉｎｇ肉瘤的转位后的第 2 2号染色体。ＥＷＳ基因与第 1 1号染色体由来的ＦＬＩ 1基因组成嵌合体 (ｃｈｉｍｅａｒａ)基因ＥＷＳ/ＦＬＩ 1。该嵌合体基因的检出 ,是诊断Ｅｗｉｎｇ肉瘤和原发性神经外胚层瘤 (ＰＮＥＴ)的重要客观依据。1 Ｅｗｉｎｇ肉
The EWS gene is derived from chromosome 2 2 after translocation of Ewing’s sarcoma. The EWS gene forms a chimera gene EWS / FLI 1 from the FLI 1 gene originating from chromosome 1 1. The detection of this chimeric gene is an important objective evidence for the diagnosis of Ewing’s sarcoma and primary neuroectodermal tumor (PNET). 1 Ewing meat
