摘要

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. We report the case of a Tunisian male child born from consanguineous marriage. He presented at the age of 4 months with failure to thrive, greasy stool and vomiting. His clinical phenotype and serum lipid profile suggested the diagnosis of ABL. The MTP gene analysis revealed a novel homozygous mutation [c.2313-2314delinsAA (p.771Tyrx)]. The parents were heterozygous for the same mutation.
