摘要:

MUT型甲基丙二酸血症(MMA)是由MMUT基因变异引起的常染色体隐性遗传病,可涉及多脏器损害,以脑损伤为主,死亡率较高。MUT型MMA目前治疗主要包括饮食治疗、左卡尼汀及维生素B12药物治疗,部分严重患者需要肝肾移植,但上述治疗效果不佳,患者预后较差。近几年,在MUT型MMA小鼠模型中已利用腺病毒载体、慢病毒载体、基因编辑、mRNA非病毒载体进行基因治疗及Ⅰ/Ⅱ期临床试验。目前相关临床试验尚处于研发早期,基因治疗有望成为MUT型MMA新治疗方法。文章对MUT型MMA基因治疗研究现状进行系统总结,为后续研究提供参考。

Abstract:

MUT-type methylmalonic acidemia (MMA) is an autosomal monogenic genetic disorder caused by mutations in the MMUT gene, which can involve multiple organ damage, mainly brain damage, and has a high mortality rate. Diet therapy, levocarnitine and vitamin B12 therapy are the main treatment method for MUT-type MMA, and some severe patients need liver and kidney transplantation, but the treatment effect and prognosis are poor. Gene therapy for MUT-type MMA using various vectors in animal model and phase 1/2 study are underway. Gene therapy in MUT-type MMA clinical trials is still in an early stage and provides a new treatment method. This article reviews the current status of gene therapy research for MUT-type MMA and aims to guide future research.
