7.6.2.2 R1297H the naturally occuring mutant protein MRP3-Arg1297His is correctly localized to the basolateral membrane and shows no significant differences in the transport of several organic anions compared to MRP3. Based on the membrane vesicle transport assays, individuals with the MRP3-Arg 1297 His variant are not expected to be affected in their ability to export MRP3 substrates into blood Homo sapiens
