A Long-term Follow-up Study of Patients with MPS IIIB from Gene Therapy Clinical Trials Involving the Administration of ABO-101 (rAAV9.CMV.hNAGLU)
- Conditions
- MPS IIIB is a devastating lysosomal storage disease, caused by a N-a-acetylglucosaminidase (NAGLU) gene defect. Infants with MPS IIIB appear normal at birth, but the disease is relentlessly progressive, with deterioration of social and adaptive abilities, neurocognitive decline, and premature death. Death typically occurs by end of the second or beginning of the third decade. Quite importantly, there is no treatment currently available for the disease.MedDRA version: 20.1Level: PTClassification code 10056890Term: Mucopolysaccharidosis IIISystem Organ Class: 10010331 - Congenital, familial and genetic disordersTherapeutic area: Diseases [C] - Congenital, Hereditary, and Neonatal Diseases and Abnormalities [C16]
