Lysosomal storage disorders comprise a group of approximately 70 types of inherited diseases resulting
due to lysosomal gene defects. The outcome of the defect is a deficiency in either of the three: namely,
lysosomal enzymes, activator protein, or transmembrane protein, as a result of which there is an unwanted accumulation
of biomolecules inside the lysosomes. The pathophysiology of these conditions is complex affecting
several organ systems and nervous system involvement in a majority of cases. Several research studies have well
elucidated the mechanism underlying the disease condition leading to the development in devising the treatment
strategies for the same. Currently, these approaches aim to reduce the severity of symptoms or delay the disease
progression but do not provide a complete cure. The main treatment methods include Enzyme replacement therapy,
Bone marrow transplantation, Substrate reduction therapy, use of molecular chaperones, and Gene therapy.
This review article presents an elaborate description of these strategies and discusses the ongoing studies for the
