101 Several molecular defects in MRP2 have been suggested to result in DJS including those which produce deficient protein maturation (Hashimoto et al., 2002; Keitel et al., 2003), proteasomal degradation (Keitel, 2003), impaired membrane sorting (Hashimoto et al., 2002; Mor-Cohen et al., 2001), loss in transport activity (Mor-Cohen et al., 2001), Figure 2 Predicted membrance topology of MRP2 (ABCC2) based on hydrophobicity analysis. Locations of the non-synonymous polymorphisms are indicated with arrows. See Table 2 for allele frequencies and description of funtional consequences.

120 Identification of Novel Polymorphisms in the MRP2 Gene- Four dimorphisms in the MRP2 gene were identified: 1) -24C3T in the 5Ј-untranslated region, 2) 842G3A in exon 7 predicting a S281N substitution, 3) 1249G3A in exon 10 predicting a V417I substitution, and 4) IVS29-35G3A.

204 Two were in non-coding regions of the gene, -24C3T and IVS29-35G3A, and two were in coding regions of the gene, 842G3A and 1249G3A predicting S281N and V417I substitutions, respectively.
