Lysosomal Storage Disorders

Lysosomal Storage Disorders Latest News

Researchers from medical and research institutions across six states and two union territories have compiled the first government-supported national biobank of a sub-section of rare diseases called Lysosomal Storage Disorders (LSDs).

About Lysosomal Storage Disorders

• Lysosomal storage diseases or disorders (LSDs) are rare genetic conditions that cause a buildup of toxic materials in your body’s cells.
• Examples: Gaucher, Pompe, Fabry, MPS I, MPS II, mucopolysaccharidoses, mucolipidoses, oligosaccharidoses, etc.
• LSDs cause a buildup of toxic materials in the body’s cells.
• The majority of the LSDs are caused by mutations in the genes encoding a lysosomal enzyme.
  • A lysosome is a membrane-bound cell organelle that contains digestive enzymes. 
  • Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts.
  • People with LSDs lack certain enzymesor a substance that helps the enzyme work (enzyme activator or modifier). Enzymes assist your cells’ lysosomes with metabolism. 
  • Without functioning enzymes, your body can’t break down fats, sugars and other substances. 
  • If those build up in your body, they can be harmful. They cause dysfunction of those organs where they accumulate and contribute to great morbidity and mortality.
• All LSDs except Hunter syndrome (MPS II) and Fabry disease are autosomal recessive disorders. This means both parents must carry the abnormal gene that prevents the body from making an enzyme with normal activity.
• LSDs usually appear during pregnancy or soon after birth and rarely, adults may develop LSDs.

Treatment for Lysosomal Storage Disorders

• There are no cures for lysosomal storage diseases. 
• But treatments can help you to manage your symptoms and lessen damage to organs and tissues.
