The nonsynonymous SNPs 361CÀA (Gln121Lys), 667CÀT (Arg223Cys), and 1460GÀT (Arg487Leu) are located in the extracellular loop between TMD1 and TMD2, TMD3 and the large cytoplasmic loop between TMD6 and TMD7, respectively.4) Using the PolyPhen program (http:/ /genetics.bwh.harvard.edu/pph/) to predict functional effects of the three amino acid substitutions, two substitutions, Arg223Cys and Arg487Leu, are expected to alter protein function based on PSIC (position-specific independent count) score differences derived from multiple alignments.

The two substitutions at the same position, Arg487His and Arg487Pro, were found in patients with severe BSEP deficiency syndrome, PFIC2.13,14) Thus, it is possible that bile acid homeostasis in the subject with Arg223Cys or Arg487Leu may be disturbed. Login to comment

280 Su-Ryang KIM, et al. 281281Genetic Variations of ABCB11 in Japanese quency in Japanese (0.196-0.267) is slightly lower than that in Caucasians (0.405) and African-Americans (0.344) (described as g.44308TÀC [Val444Ala] in a previous paper).7) Two other known variations, 896GÀA (Arg299Lys) and 2594CÀT (Ala865Val), were detected only in the Japanese population at allele frequencies of 0.010 for 896GÀA and 0.024 for 2594CÀT, respectively.7) Both variations are located in the cytoplasmic loops between TMD4 and TMD5 and between TMD8 and TMD9.
