摘要:

BackgroundIn recent years, progressive familial intrahepatic cholestasis has been classified into at least three types by genetic analysis: PFIC1, PFIC2, and MDR3. Liver transplantation is effective for treating patients with this intractable syndrome. Confirming the correct diagnosis is of paramount importance because prognosis after transplantation differs with the genetic type of the disease.MethodsSynthesis of cDNA was accomplished using RNA extracted from liver tissue of two Japanese patients with progressive familial intrahepatic cholestasis. Polymerase chain reaction was performed using 13 primer sets designed for amplification of the bile salt export pump cDNA. Direct sequencing was undertaken, and identified sequences were compared with the sequence for bile salt export pump gene registered with GenBank. In addition, gene sequences for nonprogressive familial intrahepatic cholestasis patients were analyzed.ResultsGenetic analysis of patient 1 revealed that substitutions in bile salt export pump protein sequences, namely R575X and E636G, might be the cause of the disease. In patient 2, V330X and R487H might fulfill the same role. Results of gene analysis in parents and cholestatic controls supported these conclusions.ConclusionsAbsence or presence of bile salt export protein gene mutations was confirmed as representing a useful prognostic marker for clinical course after liver transplantation.
