摘要基因组测序数据的生物信息学分析以及变异的临床相关性解读是基于二代测序的遗传病诊断全流程的核心内容.本文探讨了生物信息学分析、数据存储和数据解读环节的流程、功能、主要参数指标及建议等,经行业内临床医师、检测实验室等相关专家讨论,对符合孟德尔遗传规律的胚系突变的遗传病规范化检测达成了共识,以期为提高基于二代测序的遗传病诊断的同质性和可靠性提供指导.

abstractsBioinformatic analysis and variant classification are the key components of high-throughput sequencing-based genetic diagnostic approach.This consensus is part of the effort to develop a standardized process for next generation sequencing (NGS)-based test for germline mutations underlying Mendelian disorders in China.The flow-chart,common software,key parameters of bioinformatics pipeline for data processing,annotation,storage and variant classification are reviewed,which is aimed to help improving and maintaining a high-quality process and obtaining consistent outcomes for NGS-based molecular diagnosis.
