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.
