12 PATIENTS AND METHODS Patients The first patient was a Caucasian girl who was previously found to be heterozygous for a missense mutation in ABCG8 (c.1787T>G; L596R); no mutation was found in the other ABCG8 allele (Berge et al. 2000; Stell and Sprecher 1990). Login to comment

104 A mutation at Leu596Arg in ABCG8 has been reported in a sitosterolemic patient,4) and it has been found that ABCG8 had a similar conformation to that of ABCG5.4) It is therefore thought that the Leu596Arg mutation in ABCG8 inhabited a region similar to the Gly583Cys mutation in ABCG5.4) The results suggest a possibility that the Gly583Cys mutation in ABCG5 influences the function of ABCG5/ ABCG8.
