[hide] Genetic variations of the ABC transporter gene ABC... Drug Metab Pharmacokinet. 2009;24(3):277-81. Kim SR, Saito Y, Itoda M, Maekawa K, Kawamoto M, Kamatani N, Ozawa S, Sawada J
Genetic variations of the ABC transporter gene ABCB11 encoding the human bile salt export pump (BSEP) in a Japanese population.
Drug Metab Pharmacokinet. 2009;24(3):277-81., [PMID:19571440]
Abstract [show]
The bile salt export pump (BSEP) encoded by ABCB11 is located in the canalicular membrane of hepatocytes and mediates the secretion of numerous conjugated bile salts into the bile canaliculus. In this study, 28 ABCB11 exons (including non-coding exon 1) and their flanking introns were comprehensively screened for genetic variations in 120 Japanese subjects. Fifty-nine genetic variations, including 19 novel ones, were found: 14 in the coding exons (6 nonsynonymous and 8 synonymous variations), 4 in the 3'-UTR, and 41 in the introns. Three novel nonsynonymous variations, 361C>A (Gln121Lys), 667C>T (Arg223Cys), and 1460G>T (Arg487Leu), were found as heterozygotes and at 0.004 allele frequencies. These data provide fundamental and useful information for genotyping ABCB11 in the Japanese and probably other Asian populations.

status: NEW33 Of the 6 nonsynonymous variations, 3 were novel: 361CÀA (Gln121Lys), 667CÀT (Arg223Cys), and 1460GÀT (Arg487Leu).

status: NEW35 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 bile salt export pump (BSEP) in health and disease.
Clin Res Hepatol Gastroenterol. 2012 Dec;36(6):536-53. doi: 10.1016/j.clinre.2012.06.006. Epub 2012 Jul 12., [PMID:22795478]
Abstract [show]
The bile salt export pump (BSEP) is the major transporter for the secretion of bile acids from hepatocytes into bile in humans. Mutations of BSEP are associated with cholestatic liver diseases of varying severity including progressive familial intrahepatic cholestasis type 2 (PFIC-2), benign recurrent intrahepatic cholestasis type 2 (BRIC-2) and genetic polymorphisms are linked to intrahepatic cholestasis of pregnancy (ICP) and drug-induced liver injury (DILI). Detailed analysis of these diseases has considerably increased our knowledge about physiology and pathophysiology of bile secretion in humans. This review focuses on expression, localization, and function, short- and long-term regulation of BSEP as well as diseases association and treatment options for BSEP-associated diseases.
