研究目的:

本项目主要聚焦于外显子组测序技术检测拷贝数变异的准确性问题,从临床路径可靠性角度着手进行研究,以期可以系统评价全外显子组测序技术用于CNV检测的性能指标,比较全外显子组测序相对于CMA在性能和费效比等方面的优劣势;建立或优化CNV检测的临床路径  

Objectives of Study:

This project primarily focuses on the accuracy of exome sequencing technology in detecting copy number variations (CNVs). By investigating from the perspective of clinical pathway reliability the study aims to systematically evaluate the performance metrics of whole-exome sequencing (WES) for CNV detection compare the advantages and disadvantages of WES versus chromosomal microarray analysis (CMA) in terms of performance and cost-effectiveness and establish or optimize clinical pathways for CNV detection.
