摘　　要：约有80%的罕见病与基因变异有关。基因测序是发现基因变异的主要方法,但目前的基因变异阳性检出率平均不到40%,难以满足临床需求。文章从基因编码区、非编码区、DNA甲基化、检测后分析与基因重分析等方面将基本概念和最新研究进展进行整合,介绍提高变异基因检出率的思路和方法,以期对临床基因检测有所裨益。Approximately 80%of rare disorders are associated with genetic variations.Although gene sequencing has emerged as the primary approach for identifying genetic variations,the current average positive detection rate remains below 40%,falling short of clinical requirements.This review aims to improve the detection rate of mutant genes by integrating fundamental concepts and recent advancements in several key areas,such as gene coding regions,non-coding regions,DNA methylation,post-detection analysis and gene reanalysis.It aims to propose strategies and methodologies that may contribute to more effective clinical gene detection.
