About Lysosomal Storage

Lysosomal Storage Disorders

Lysosomal Storage Disorders (LSDs) are caused by a lack of enzymes that normally get rid of unwanted substances in the cells of the body. These enzymes are found in sac-like structures within cells, called lysosomes.

The lysosome is the cell’s recycling center, breaking down unwanted material into simple products for re-use in the cell. When genetic mutations prevent these enzymes from working properly, a toxic buildup can occur in the lysosome, damaging cells and organs in the body, including the kidneys, liver, spleen, heart, lungs, brain, eyes, skin, and bones.

Depending on the type of lysosomal storage disease, symptoms may vary. They can be severe and appear soon after birth, or mild and not appear until later in life.

The many LSDs we diagnose and manage include Gaucher, Tay-Sachs, Fabry, Niemann-Pick, Pompe, Canavan, Krabbe, metachromatic leukodystrophy, and themucopolysaccharidoses. NYU Langone treats one of the largest populations with Gaucher disease Type 1 in the country.
