80 RESULTS Mutations Detected in Patients with PFIC Of 17 patients with low-GGT PFIC, mutations in ABCB11 were found in 5 patients, including a sibling pair (patients 1 and 2) with compound heterozygous c.850GϾC (p.V284L) and c.1145delC (p.Ala382AlafsX16) mutations.12 Patient 3 had compound heterozygous c.547AϾG (p.M183V)/c.908GϾA (p.R303K) mutations.

102 Analysis of Mutations in Normal Controls All the missense mutations detected above were tested in 80 normal control subjects (160 alleles), using DHPLC for M183V (exon 7), V284L (exons 9), R303K (exon 9), R487H (exon 14), L827I (exon 21), and G1004D (exon 23).
