Overview
Chylomicron retention disease is an autosomal recessive hypolipoproteinemia disease. Chylomicron retention disease is a very rare condition that is caused by a mutation in SAR1B gene located on chromosome 5q31.1 leading to deficiency in the secretion of apolipoprotein B from enterocytes. While the synthesis chylomicron synthesis is totally affected, VLDL synthesis is intact.
