Lysosomal Storage Disorders

There are more than 40 diseases classified as lysosomal storage disorders (LSDs), each resulting from an inherited monogenetic defect that causes a specific enzymatic deficiency or malfunction, resulting in accumulation of some substrate in cell lysosomes. In addition to Gaucher disease, other LSDs include Tay-Sachs disease, Mucopolysaccharidoses, and Fabry disease.

While individually most of these diseases are rare, as a group their incidence is about 1 in 7,700 live births[1] [2] -higher than many physicians may realize.

Most LSDs can present across a continuum of clinical severity. They are all progressive in nature and may cause multi-systemic, irreversible damage that can be seriously debilitating and even life-threatening. Thus early identification, diagnosis, and optimal intervention are essential.

LSDs require a multidisciplinary approach to care, including disease-specific treatment options available for some LSDs and general medical management.

Gaucher Cells

Gaucher cells accumulate and displace healthy normal cells in bone marrow and organs such as the liver and spleen. This accumulation causes a host of signs, including skeletal deterioration, anemia, and organ dysfunction.

Gaucher Registry

For more than a decade, the Gaucher Registry has been a global resource to the medical and patient communities, helping to improve outcomes in patients with Gaucher disease. Learn more about participating in the Gaucher Registry ยป
