title: Fat-soluble vitamin deficiency in pregnancy: a case report and review of abetalipoproteinemia.
abstract: BACKGROUND
  Abetalipoproteinemia (ABL) is a metabolic disorder resulting in poor absorption of fat-soluble vitamins.
  
  
  METHODS
  Two pregnancies in a woman with ABL are reported, contrasting outcomes with subtherapeutic and normal vitamin levels.
  
  
  CONCLUSIONS
  Fat-soluble vitamin levels in pregnancy are critical for many aspects of fetal development. This report details a congenital ophthalmologic finding that may be associated with vitamin A deficiency.
