Wolman disease

(vol'măn )

[Moshe Wolman, Polish-born Israeli neuropathologist, 1914–2009]

A rare autosomal recessive lysosomal storage disease with onset and death occurring in the first year of life.

Incidence: Wolman disease occurs in approx. 1 of 500,000 live births. In the U.S., approx. 8 infants are born with Wolman disease each year.

Causes: Wolman disease is an autosomal recessive disease, which causes a deficiency of the enzyme lysosomal acid lipase, which breaks down certain lipids inside the cells.

Symptoms and Signs: Abdominal distention, vomiting, and significant enlargement of the liver or spleen may occur.

Treatment: Although there is no cure for Wolman disease, enzyme replacement therapy with sebelipase alfa improves lipid and liver function. SYN: lysosomal acid lipase deficiency.
