Intrahepatic cholestasis of pregnancy (ICP) typically presents in the late second or third trimester and carries an increased risk of fetal demise and neonatal morbidity and mortality. First trimester onset is rare and should alert the physician to explore a possible genetic basis for the disease. We present a 26-year-old Hispanic gravida 3, para 0202 with recurrent first-trimester onset ICP. Given her atypical history and presentation, a genetic cause was considered. She was found to have a novel heterozygous missense mutation in the ABCB4 canalicular membrane transport gene. First or early second trimester presentation of ICP should prompt investigation into genetic causes of the disease. Individualized family counseling and neonatal evaluation should be addressed if a disease-causing genetic mutation is diagnosed.
