Identification of a novel mutation of MTP gene in a patient with abetalipoproteinemia.
Abetalipoproteinemia (ABL), or Bassen-Kornzweig syndrome, is a rare autosomal recessive disorder of lipoprotein metabolism, characterized by fat malabsorption, hypocholesterolemia retinitis pigmentosa, progressive neuropathy and acanthocytosis from early infancy. We describe the clinical and molecular characterization of a 6-month-old infant born of consanguineous, apparently healthy parents fr...
متن کاملAbetalipoproteinemia in an infant with severe clinical phenotype and a novel mutation.
Abetalipoproteinemia (ABL) is a rare autosomal disorder characterized by extremely low levels of plasma lipids and apolipoprotein B (apoB) with a variable phenotype. Mutations in the MTP gene encoding the microsomal triglyceride transfer protein (MTP) cause the disease. A five-month-old boy, born from consanguineous parents, with chronic diarrhea and severe malnutrition had extremely low plasma...
متن کاملMolecular characterization of Tunisian families with abetalipoproteinemia and identification of a novel mutation in MTTP gene
BACKGROUND Abetalipoproteinemia (ABL; OMIM 200100) is a rare monogenic disorder of lipid metabolism characterized by reduced plasma levels of total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C) and almost complete absence of apolipoprotein B (apoB). ABL results from genetic deficiency in microsomal triglyceride transfer protein (MTP; OMIM 157147). In the present study we investi...
متن کاملA Male Infant with Abetalipoproteinemia: A Case Report from Iran
Abetalipoproteinemia (ABL) is a very rare autosomal recessive disorder caused by mutations in the microsomal triglyceride transfer protein gene (MTTP). ABL is characterized by lack of lipids and apolipoprotein B (apoB) in plasma, fat malabsorption and various clinical manifestations. We describe a 12-month-old infant boy, born from consanguineous parents and presented with diarrhea, steatorrhea...
متن کاملAbnormalities of high density lipoproteins in abetalipoproteinemia.
DETAILED STUDIES OF THE HIGH DENSITY LIPOPROTEINS FROM THREE PATIENTS WITH ABETALIPOPROTEINEMIA HAVE REVEALED THE FOLLOWING PRINCIPAL ABNORMALITIES: 1) High density lipoprotein 3 (HDL3) is reduced in both absolute and relative concentration, although HDL2 is present in normal amounts. 2) The phospholipid distribution of both HDL fractions is abnormal, with low concentrations of lecithin and an ...
