90 A small amount of exon skipping was also seen for the SNPs G319G (c.957AϾG; 95%; Fig. 2B) and E1186K (c.3556GϾA; 90%; Fig. 2F). Login to comment
119 The potential to modulate a selection of aberrant ABCB11 pre-mRNA splicing was assessed through the addition of the splicing factors SC35, hnRNPA2, and hnRNPH.25 The effect on the nucleotide change predicted to cause E1186K (c.3556GϾA) was also assessed, as the role of this SNP in the development of disease is unclear. Login to comment
128 Finally, the splicing of the SNP E1186K (c.3556GϾA) was maintained at 90% of wild-type levels on the addition of hnRNPA2 and hnRNPH, but was inhibited by SC35 (Fig. 4C). Login to comment

144 In addition, several rare BSEP polymorphisms, including 616A > G (Ile206Val), 1674G > C (Gln558His), 1772A > G (Asn591Ser), and 3556G > A (Glu1186Lys) were also associated with significantly impaired taurocholate transport compared with wild-type BSEP, exhibited by retained increased intracellular taurocholate accumulation (P < 0.05).
