Abstract

This review analyzes strategies to prevent or reduce the transmission of diseases caused by pathogenic variants in mitochondrial DNA (mtDNA). Among these, we will focus on prenatal screening, preimplantation genetic testing, gene-editing techniques, other molecular tools, and selected heterologous mitochondrial replacement techniques (MRTs), explaining their status and the uncertainties surrounding their clinical application. After this analysis and review, we recognise the limitations of the efficacy of prenatal and preimplantation genetic testing for mitochondrial DNA pathogenic variants, the legal constraints on gene editing, and the status of mitochondrial replacement techniques. MRTs are a safe and possibly more effective alternative for preventing diseases caused by mitochondrial DNA pathogenic variants.

线粒体DNA致病变异传播的最新进展:回顾预防治疗方案。
本文综述了预防或减少由线粒体DNA (mtDNA)致病变异引起的疾病传播的策略。其中,我们将重点关注产前筛查,植入前基因检测,基因编辑技术,其他分子工具,以及选择的异源线粒体替代技术(MRTs),解释其现状和临床应用的不确定性。在此分析和回顾之后,我们认识到线粒体DNA致病变异的产前和植入前基因检测有效性的局限性,基因编辑的法律约束以及线粒体替代技术的现状。对于预防线粒体DNA致病变异引起的疾病,磁共振成像是一种安全且可能更有效的替代方法。

期刊介绍: The Journal of Assisted Reproduction and Genetics publishes cellular, molecular, genetic, and epigenetic discoveries advancing our understanding of the biology and underlying mechanisms from gametogenesis to offspring health. Special emphasis is placed on the practice and evolution of assisted reproduction technologies (ARTs) with reference to the diagnosis and management of diseases affecting fertility. Our goal is to educate our readership in the translation of basic and clinical discoveries made from human or relevant animal models to the safe and efficacious practice of human ARTs. The scientific rigor and ethical standards embraced by the JARG editorial team ensures a broad international base of expertise guiding the marriage of contemporary clinical research paradigms with basic science discovery. JARG publishes original papers, minireviews, case reports, and opinion pieces often combined into special topic issues that will educate clinicians and scientists with interests in the mechanisms of human development that bear on the treatment of infertility and emerging innovations in human ARTs. The guiding principles of male and female reproductive health impacting pre- and post-conceptional viability and developmental potential are emphasized within the purview of human reproductive health in current and future generations of our species. The journal is published in cooperation with the American Society for Reproductive Medicine, an organization of more than 8,000 physicians, researchers, nurses, technicians and other professionals dedicated to advancing knowledge and expertise in reproductive biology.
