chylomicron retention diseaseAn autosomal recessive disorder (OMIM:246700) of severe fat malabsorption associated with failure to thrive in infancy, characterised by deficiency of fat-soluble vitamins, low serum cholesterol and selective absence of chylomicrons from blood. Affected individuals accumulate chylomicron-like particles in membrane-bound compartments of enterocytes, which contain large cytosolic lipid droplets.
Defects in SAR1B, which encodes a protein involved in transport from the endoplasmic reticulum to the Golgi apparatus, cause chylomicron retention disease.
