Abetalipoproteinemia is the rare inherited disorder characterized by the failure to assemble apolipoprotein B–containing lipoproteins, leading to fat malabsorption and fat-soluble vitamin deficiencies. This condition was described by Bassen and Kornzweig, so the classic name for it is Bassen-Kornzweig syndrome. The name reflects the same disease process as abetalipoproteinemia, making it the best answer. Other listed disorders—sitosterolemia and Tangier disease—are different lipid disorders with distinct genetic defects and clinical features, not the same condition described as abetalipoproteinemia. Some texts also use Anderson's disease as another historical label, but Bassen-Kornzweig syndrome is the most widely recognized synonym in modern references.
