Abstract
Late-onset liposomal acid lipase deficiency (LAL deficiency), previously known as Cholesteryl ester storage disease (CESD) is a rare genetic lysosomal storage disorder caused by deficiency of lysosomal acid lipase (LAL) due to mutations in the LIPA gene. LAL deficiency is a systemic disease that leads to the accumulation of fat and inflammation in the liver, premature atherosclerosis and gastrointestinal disease. Most of the patients require liver transplantation due to decompensated cirrhosis. Enzyme replacement therapy has been approved and is available in many countries. Here we describe a 16-year-old patient who was diagnosed to have late-onset LAL deficiency when he presented to us with ESLD. Subsequently, he underwent a living-donor liver transplant (LDLT) successfully. We discuss the ethical dilemmas in considering LDLT for LAL deficiency.
