Genomic instability is a hallmark of cancer and, as such, structural alterations and fusion genes are common events in the cancer landscape. RNA sequencing (RNA-Seq) is a powerful method for profiling cancers, but current methods for identifying fusion genes are optimised for short reads. JAFFA (https://github.com/Oshlack/JAFFA/wiki) is a sensitive fusion detection method that outperforms other methods with reads of 100 bp or greater. JAFFA compares a cancer transcriptome to the reference transcriptome, rather than the genome, where the cancer transcriptome is inferred using long reads directly or by de novo assembling short reads.
基因组不稳定性是癌症的一个标志,因此,结构改变和融合基因是癌症领域中的常见事件。RNA测序(RNA-Seq)是一种用于分析癌症的强大方法,但目前用于识别融合基因的方法是针对短读长进行优化的。JAFFA(https://github.com/Oshlack/JAFFA/wiki)是一种灵敏的融合检测方法,在处理100 bp或更长读长时比其他方法表现更优。JAFFA将癌症转录组与参考转录组进行比较,而不是与基因组进行比较,其中癌症转录组是直接使用长读长或通过对短读长进行从头组装来推断的。
