72 Of the remaining three substitutions, two were also seen in some control subjects, whereas E636G was not seen in any of the control subjects. Results of genetic analyses performed on family members revealed that R575X was paternal in origin, whereas E636G was maternal in origin. None of these mutations were observed in the asymptomatic brother. Login to comment

86 The R575X mutation seen in patient 1 of the present study is a nonsense mutation in the first nucleotide binding fold of the BSEP protein, whereas the E636G mutation is a missense mutation located between the first nucleotide binding fold and the seventh transmembrane domain. Login to comment
