title: Stop-codon read-through for patients affected by a lysosomal storage disorder.
abstract: Lysosomal storage disorders are a group of inherited diseases that can result in severe and progressive pathology due to a specific lysosomal dysfunction. Current treatment strategies include bone-marrow transplantation, substrate reduction, chemical-chaperone and enzyme-replacement therapy. However, each of these treatments has its limitations. Enhanced stop-codon read-through is a potential alternative or adjunct therapeutic strategy for treating lysosomal-storage-disorder patients. Premature stop-codon mutations have been identified in a large cohort of patients with a lysosomal storage disorder, making stop-codon read-through a possible treatment for this disease. In lysosomal-storage-disorder cells (mucopolysaccharidosis type I, alpha-L-iduronidase deficient), preclinical studies have shown that gentamicin induced the read-through of premature stop codons, resulting in enzyme activity that reduced substrate storage.
