摘要目的 利用基因的审核归档策略进行矮小测序基因包设计.方法 本研究详细介绍了基因审核归档策略,通过收集遗传学证据和功能证据,对基因-疾病关系进行分类,并且以身材矮小诊断基因包的设计为例,展示了基因审核归档过程对靶向测序基因列表设计的影响.结果 通过基因审核归档,将机械搜索到的身材矮小基因包基因数量从1 276个精简到有效的705个,利用该基因包对全国371例身材矮小患者进行测序分析,诊断率可达到19.7%.该基因审核归档过程降低了假阳性的几率,同时在不影响诊断率的前提下降低了诊断成本和劳动时间.结论 基因审核归档是二代测序诊断中的重要环节,应随着基因诊断的普及而得到广泛重视和应用.

abstractsObjective Design short stature panel with gene curration strategy.Methods The gene curation process was introduced in detail.The strength of a gene-disease relationship was evaluated based on publicly available genetic and experimental evidence.This process in short stature panel design and its effect on gene selection was further demonstrated.Results After gene curation, the number of gene in list was effectively decreased from 1 276 to 705.The panel sequencing reached a diagnosis rate of 19.7% among a cohort of 371 nation-wide ascertained short stature patients.The gene curation process reduced the risk of false positive findings and decreased diagnostic cost and working hours without affecting the diagnosis rate.Conclusion Gene curation is an important step for NGS-based test and should be widely exercised.
