融合基因是指两个独立基因的编码区首尾相连所形成的且置于同一套调控序列控制的产物,研究表明许多癌症的发生与融合基因存在密切的联系。融合基因可作为癌症治疗的靶点,在癌症诊断及治疗领域中融合基因的研究具有重要意义。部分融合基因驱动癌症的机制已被初步揭示,但是有些真实存在的在肿瘤发生发展过程中有重要意义的融合基因由于工具和实验技术限制还未被发现。因此,对融合基因的分析预测研究方法逐渐成为关注的热点之一。本文探讨了目前常用的关于融合基因的分析工具及方法,为融合基因在癌症中的研究提供思路。

Fusion genes are the products of two independent genes whose coding regions are linked and controlled by the same set of regulatory sequences．Studies have shown that many cancers are closely linked to gene fusions．Fusion genes can be used as targets for cancer therapy,and the study of fusion genes is of great importance in cancer diagnosis and treatment．Some of the mechanisms of fusion genes driving cancer have been initially revealed,but there are more fusion genes which are important in the process of tumor development have not been discovered due to the limitation of tools and experimental techniques．Therefore,the analysis and prediction methods of fusion genes are becoming a hot topic of interest．In this paper,we discuss the commonly used analytical tools and methods on fusion genes to provide ideas for the study of fusion genes in cancer．
