The dramatic advances in genetic sequencing technologies used in research laboratories are now entering the clinic, and applications of whole-genome and whole-exome sequencing to disease diagnosis, predisposition, and treatment will soon be commonplace. However, the standards and methods for identifying clinically relevant variants are currently being debated and defined. Multiple agencies worldwide have recognized that we have reached an exciting and critical transition point into the clinic, and many important issues are being discussed that impact how genetic variation data in the clinic will be interpreted and used. The 2013 annual scientific meeting of the Human Genome Variation Society (HGVS) had as its main theme the discovery, interpretation, and dissemination of clinically relevant DNA variants. The meeting featured the continuously developing technology of databasing genetic variation and computational tools for allelic variant discovery. Attention was given to curating and integrating these data with clinical findings, including approaches to distinguish between functional alleles underlying clinical phenotypes and benign sequence variants and making data sources interoperable and functional for clinical diagnostic utility, citing examples in specific diseases.
研究实验室中使用的基因测序技术取得的巨大进展如今正进入临床领域,全基因组和全外显子组测序在疾病诊断、易感性评估及治疗方面的应用很快将变得司空见惯。然而,目前用于识别临床相关变异的标准和方法仍在讨论和界定之中。全球多个机构已经认识到,我们正处于一个激动人心且关键的向临床领域过渡的阶段,许多重要问题正在被讨论,这些问题会影响临床中基因变异数据将如何被解读和使用。人类基因组变异协会(HGVS)2013年年度科学会议的主题是临床相关DNA变异的发现、解读及传播。会议展示了不断发展的基因变异数据库技术以及用于等位基因变异发现的计算工具。会议还关注了将这些数据与临床发现进行整理和整合,包括区分临床表型潜在功能等位基因和良性序列变异的方法,以及使数据源具有临床诊断实用性的互操作性和功能性,并列举了特定疾病中的实例。
