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.

Key words: methylmalonic acidemia, MMUT gene, gene therapy
