7 Conclusion The results of this study suggest that the possession of R1381S, S346F, and S607N types of ABCC3 sequences may be a possible risk factor for the acquisition of hepatotoxicity, due to their poor ability to transport toxic compounds across the sinusoidal membrane. Login to comment

200 In conclusion, we have analyzed 11 nonsynonymous SNPs found in the SNP database of ABCC3 and found that three of these are expected to be nonfunctional for clear reasons; the impaired function of S346F and S607N is because of impaired transport function, whereas that of R1381R is because of impaired intracellular trafficking.
