The use of whole exome sequencing (WES) for the detection of disease-causing variants of genetic diseases and for non-invasive prenatal screening (NIPS) of fetal aneuploidies are two major clinical applications of next generation sequencing (NGS). This article has summarized the official documents developed and updated by the American College of Medical Genetics and Genomics (ACMG) on governing WES and NIPS. These include the development of expert consensus policies and position statements on an ongoing basis to guide clinical application of NGS technology and variant analysis, establish evidence-based practical resources, as well as standards and guidelines to govern diagnosis and screening. These ACMG documents are valuable references to Chinese geneticists, but direct adoption of these standards and guidelines may not be practical due to the differences in disease-associated variant frequencies in Chinese population, socioeconomic status, and medical practice between the two countries. It is hoped that this review could facilitate the development of NGS and NIPS standards and guidelines that are consistent with international standards and concordant with medical genetics practice in China to provide high-quality, efficient and safe clinical services for patients and their families with genetic diseases.
使用全外显子组测序(WES)检测遗传疾病的致病变异以及用于胎儿非整倍体的无创产前筛查(NIPS)是下一代测序(NGS)的两个主要临床应用。本文总结了美国医学遗传学与基因组学学会(ACMG)制定和更新的关于管理WES和NIPS的官方文件。这些文件包括持续制定专家共识政策和立场声明,以指导NGS技术的临床应用和变异分析,建立基于证据的实用资源以及用于指导诊断和筛查的标准与指南。这些ACMG文件对中国遗传学家而言是有价值的参考资料,但由于两国在疾病相关变异频率、社会经济状况以及医疗实践方面存在差异,直接采用这些标准和指南可能并不实际。希望这篇综述能够推动制定与国际标准一致且符合中国医学遗传学实践的NGS和NIPS标准与指南,从而为患有遗传疾病的患者及其家庭提供高质量、高效且安全的临床服务。
