Lysosomal Storage Disorders Lsds

Waste builds up in the cells which can cause a variety of health problems and even be life threatening if untreated.

Lysosomal storage disorders lsds.

Lysosomes are the microscopic recycle bins in the cells that store break down and recycle large unwanted molecules by utilizing very specific enzymes. They affect the lysosome a structure in your cells that breaks down substances such as proteins carbohydrates and old. Lysosomal storage disorders lsds are genetic disorders resulting in enzyme deficiencies within the lysosomes of the body s cells. These disorders can affect both children and adults.

Gaucher disease is one of the most common lysosomal storage disorders lsds. In people with lysosomal storage disorders the enzymes don t work properly. ˌlaɪsəˈsoʊməl are a group of about 50 rare inherited metabolic disorders that result from defects in lysosomal function. There are over 50 lysosomal storage disorders including tay sachs disease and gaucher disease.

While clinical trials are in progress on possible treatments for some of these diseases there is currently no approved treatment for many lysosomal storage diseases. Lysosomal storage diseases lsds. Lsds are inherited disorders resulting from a lack of specific enzymes that break down certain lipids fats or carbohydrates sugars in the body cells. Lysosomal storage diseases lsds are a rare distinct group of disorders with complex diagnosis and limited epidemiology data such as pompe disease.

Lysosomal storage disorders lsds are a large group of more than 50 different inherited metabolic diseases which in the great majority of cases result from the defective function of specific lysosomal enzymes and in few cases of non enzymatic lysosomal proteins or non lysosomal proteins involved in lysosomal biogenesis. Lysosomes are sacs of enzymes within cells that digest large molecules and pass the fragments on to other parts of the cell for recycling. There are approximately 50 known lsds each caused by a unique gene mutation which leads to a disease specific enzyme that is deficient or malfunctioning. New lysosomal storage disorders continue to be identified.

The first step in a diagnostic workup of an individual suspected of having a lysosomal storage disorder lsd includes urine analyses for metabolites associated with mucopolysaccharidoses oligosaccharidoses disorders of sulfatide degradation and lsds with characteristic urine profiles.
