Identification of a novel mutation of MTP gene in a patient with abetalipoproteinemia

Journal Title: Annals of Hepatology - Year 2011, Vol 10, Issue 2

Abstract

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 from Iran. The patient was hospitalized because of failure to thrive, greasy stool and vomiting. The patient’s serum lipid profile, the clinical phenotype and the duodenal histology suggested the clinical diagnosis of ABL. The MTP gene analysis by direct sequencing revealed a novel homozygous mutation (c.1586 A > G-H529R). The parents were heterozygotes for the same mutation and interestingly the father showed a lipid profile characterized by a slight reduction of total and LDL-cholesterol plasma levels.
