What is LAL-D?
Lysosomal Acid Lipase Deficiency (LAL-D) is a genetic, progressive ultra-rare metabolic disease. It is associated with multi-organ damage in infant, pediatric and adult patients.
In patients suffering from LAL-D, genetic mutations result in a loss in activity, or decrease, of the LAL enzyme; this leads to ongoing accumulation of cholesteryl esters and triglycerides in the liver, blood vessel walls and other tissue. This can result in progressive complications in multiple organs, including the liver, spleen, and intestine, and leads to some of the symptoms described below.
Before it was realized that LAL-D is the same disease in infants, children, and adults, the disease was referred to as ‘Wolman Disease’ in infants, and ‘Cholesteryl Ester Storage Disease’ for children and adults.
Treatments for LAL-D are available. Currently, an enzyme replacement therapy exists to replace the missing enzyme, helping to break down fats and stop them from building up in the body’s cells.
