What research has been conducted on gene therapy for AGU?

There have already been several preclinical studies where a healthy gene was delivered via virus carrier to AGU mice to replace a mutated AGA enzyme. In all cases, the transfer of the healthy AGA gene was successful in producing an enzyme that decreased toxic buildup, indicating that gene therapy in humans may work. Researchers will move into primate research next.

Although this treatment is many years away – it will need to be studied in human clinical trials and approved by the FDA – it is likely that gene therapy for AGU would be a one-time injection.
