chylomicron retention disease symptom
chylomicron retention disease an autosomal recessive disorder of lipid metabolism consisting of inability of cells of the intestinal wall to secrete chylomicrons, so that a person has severe steatorrhea; affected children have diarrhea and growth retardation. Chylomicron retention disease (Anderson disease) In chylomicron retention disease, a hereditary disorder, the body cannot make chylomicrons. Genetic testing is most widely used to identify the change in the chromosome, gene, or protein that is associated with chylomicron retention disease. Volume 25, Issue 11 p. 1755-1756. Associated genetic disorders includes abetalipoproteinemia, familial hypobetalipoproteinemia, and chylomicron retention disease. The specific molecular defect was identified in 2003 and consists of mutations in the SAR1B or SARA2 gene encoding for intracellular SAR1B GTPase protein. tations in APOB (homozygous FHBL type-1), MTTP (abetalipoproteinemia), or SAR1B (chylomicron retention disease). Chylomicron retention disease (Anderson disease) Chylomicron retention disease is a very rare autosomal recessive condition caused by deficient apo B secretion from enterocytes. Since there are many genes (~20,000), there are many possible defects. Malabsorption, hypocholesterolemia, and fat-filled enterocytes with increased intestinal apoprotein B. Chylomicron retention disease. The diagnosis of Anderson's disease or chylomicron retention disease is frequently delayed because of their nonspecific signs and symptoms. In hypobetalipoproteinemia the low density lipoprotein . Chylomicron retention disease begins in infancy or early . Chylomicron retention disease (CRD) is an autosomal recessive disorder associated with biallelic Sar1b mutations leading to defects in intracellular chylomicron (CM) trafficking and secretion. The defect remains unknown but presumably involves the synthesis or secretion of chylomicrons. This is needed to help molecules called chylomicrons to carry fats and cholesterol (lipids) from the intestine to the bloodstream and to absorb certain vitamins.
