5 Using denaturing high-performance liquid chromatography (DHPLC), five different mutations were identified in four affected families: three novel mutations in BSEP (G19R-g181c, S226L-c803t and G877R-g2755a), one novel mutation in MDR3 (IVS14+6 t/c) and one heterozygous mutation in ATP8B1 (R600W, in a family with the PFIC1/PFIC2 phenotype).

61 Screening this family`s DNA yielded two novel heterozygous mutations in BSEP (G19R-g181c and S226L-c803t). Login to comment
73 In total, five mutations were discovered in the ATP8B, BSEP and MDR3 genes; that is, three novel mutations in BSEP (G19R-g181c, S226L-c803t and G877R-g2755a), one novel mutation in MDR3 (IVS14+6 t/c) and only one heterozygous mutation in ATP8B1 (R600W). Login to comment
75 The patients from family 3 were compound heterozygotes for two mutations in BSEP-G19R and S226L-and the patient from family 2 had a hemizygous mutation in BSEP-G877R. Login to comment
76 S226L and G877R are missense mutations at the conserved and active sites of the proteins (ConSeq; http://conseq.tau.ac.il; Figure 5), and G19R is located at the N-terminal region of the BSEP protein. Login to comment
