Chylomicronemia syndrome - Overview

Alternative Names

Familial lipoprotein lipase deficiency

Definition of Chylomicronemia syndrome:

Chylomicronemia syndrome is a disorder passed down through families in which the body does not break down fats (lipids) correctly. This causes a type of fats called chylomicrons to build up in the blood.

Causes, incidence, and risk factors:

Chylomicronemia syndrome is a rare genetic disorder. It occurs when a protein (enzyme) called lipoprotein lipase (LpL) is broken or missing. LpL is normally found in fat and muscle and helps break down certain lipids. When LpL is missing or broken, chylomicrons build up in the blood. This is called chylomicronemia.
