Metabolic disorders such as argininosuccinic and glutaric aciduria, methylmalonic acidemia, homocystinuria or primary hyperoxaluria require specific diets to prevent the accumulation of substances that the body can’t process. Current treatments mainly focus on managing symptoms and metabolite levels, and do not always prevent the progressive deterioration caused by mutations associated with the condition. However, emerging gene therapies hold promise for transforming these diseases by targeting their underlying causes, as presented in the oral abstract session, “Gene and cell therapy for metabolic diseases” of the ongoing 28th Annual Meeting of the American Society of Gene & Cell Therapy (ASGCT) meeting in New Orleans.
