During the preceding 20 days, she had received a 10-day course of cefprozil and 2 doses of a homeopathic preparation of cantharidin for cystitis. Severe conjugated hyperbilirubinemia was present with normal \u03b3-glutamyl transpeptidase activity. Liver biopsy revealed marked canalicular and hepatocellular cholestasis, with moderate hepatocellular disarray, as well as evidence of chronicity, including moderate portal-tract and perisinusoidal fibrosis. Immunohistochemical studies revealed that bile salt export pump expression was preserved, whereas canalicular \u03b3-glutamyl transpeptidase expression was largely absent. An inherited cholestatic disorder was suspected. The entire coding region of ABCB11, encoding bile salt export pump, was analyzed. The patient was found to be a compound heterozygote for the missense mutation c.3148C&amp;gt;T (p.Arg1050Cys) associated with benign recurrent intrahepatic cholestasis type 2 in the homozygous state and for the nonsense mutation c.3904G&amp;gt;T (p.Glu1302Ter) associated with progressive familial intrahepatic cholestasis type 2. Despite initial improvement with ursodeoxycholic acid, over the course of 5 years the patient developed cirrhosis that required liver transplant. Our report emphasizes the need for molecular studies even in patients with putatively \u201cexplained\u201d cholestasis to reveal the entire spectrum of inherited cholestatic disorders.<\/jats:p>","DOI":"10.1542\/peds.2018-2146","type":"journal-article","created":{"date-parts":[[2019,4,23]],"date-time":"2019-04-23T12:25:14Z","timestamp":1556022314000},"source":"Crossref","is-referenced-by-count":9,"title":["Beyond
