概括

同时的RNA综合基因组分析 (CGP) 与单独的DNA-CGP相比,显著改善了对伴侣诊断 (CDx) 结构变异 (SV) 的检测,特别是NRG1和NTRK融合. 综合DNA/RNA分析增强了针对性治疗的SV检测.

科学领域:

在瘤学瘤学.
基因组学就是基因组学.
分子诊断学分子诊断

背景情况:

在结构变异 (SV) 检测中,DNA综合基因组分析 (CGP) 是有效的.
同时的RNA-CGP可能会提高SV检测的灵敏度.

研究的目的:

评估综合DNA和RNA-CGP相比单独DNA-CGP的附加值,用于检测伴侣诊断 (CDx) SVs.
使用并行DNA和RNA-CGP的方法量化特定CDx基因SV的检测率.

主要方法:

对5129名接受并行DNA和RNA-CGP的患者进行了回顾性分析.
对CDx SVs的检测率的检查包括ALK,BRAF,FGFR2/3,METEx14,NTRK1/2/3,NRG1,RET和ROS1.3等.

主要成果:

CDx基因SVs的患病率在固体瘤中为3.3%,在批准的瘤类型 (ITT) 中为2.0%.
仅RNA-CGP就检测到了20%的ITT和26%的固体瘤CDx SVs.
检测NRG1和NTRK融合显著改善,67%的相关癌症仅通过RNA识别.

结论:

Next-generation Sequencing

Next-generation Sequencing

The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.

RNA-seq

RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...
