Abstract

<abstract abstract-type="main"> <title>Abstract</title> <p>Acute fatty liver of pregnancy (AFLP) is a devastating disorder of the maternal liver in the third trimester. Recent studies have demonstrated an association between AFLP and fetal fatty acid oxidation disorders. Here, we report a case of AFLP caused by fetal mitochondrial trifunctional protein (TFP) deficiency. A 21‐year‐old parous woman presented with nausea, genital bleeding and abdominal pain at 33 weeks of gestation. Laboratory data revealed hepatic failure and disseminated intravascular coagulopathy. The patient underwent emergency cesarean section and was diagnosed with AFLP from the clinical characteristics. She was successfully treated with frequent plasma exchange. The newborn presented severe heart failure and died on the 39th day after birth. Tandem mass spectrometry indicated long‐chain fatty acid oxidation disorder. Gene analysis demonstrated homozygous mutation in exon 13 of <italic>HADHB</italic>, the gene responsible for mitochondrial TFP deficiency. The parents carried a heterozygous mutation at the same location in <italic>HADHB</italic>.</p> </abstract>
