Serious pregnancy complications in a patient with previously undiagnosed carnitine palmitoyltransferase 1 deficiency

Fetal defects in mitochondrial beta-oxidation have been linked with an increased risk for acute fatty liver of pregnancy and preeclampsia-related conditions. A woman with previously undiagnosed carnitine palmitoyltransferase 1 deficiency experienced hemolysis, elevated liver enzymes, low platelets-like syndrome late in her first pregnancy with an unaffected fetus. Carnitine palmitoyltransferase 1 deficiency should be considered as a potential cause of life-threatening complications of pregnancy.
