Fig. 1 Pedigree with genetic data. Squares represent males, and circles represent females. Solid symbols indicate affected individuals. Allele sizes for 5 genetic markers spanning the FIC1 region on chromosome 18q are shown. The markers are placed in their order along the chromosome from centromere to telomere, except that the order of D18S1401 relative to D18S977 is unknown. The boxes outlined in various patterns represent different copies of the FIC1 region present in the family. The data showing that 1 affected child (39f) does not have either of the copies of the FIC1 region that are present in the other 3 affected children strongly argue that the liver bile acid transport defect in this family is not a form of PFIC1.

Fig. 3 Physical growth for patient 39c. Weight (lower graph) and height (upper graph) were depressed before treatment, but increased with ursodiol treatment to 90th percentile for weight and 75th percentile for height.

Fig. 5 (A) Subcapsular wedge biopsy specimen of the liver showing early bridging fibrosis (H&E; original magnification 40×). (B) Higher-power photomicrograph illustrating portal and lobular inflammation with spotty hepatocyte necrosis, interface hepatitis, and mild ductular proliferation consistent with nonspecific reactive hepatitis. Cholestasis, bile duct paucity, and pseudoacinar change are absent (H&E; original magnification 100×). The biopsy specimen was taken after 2 months of ursodiol treatment.
