2 Two mutations (R557X and H160FsX173) were predicted to generate short truncated proteins; two mutations (E284K and Y482C) were located in the first extracellular loop and two (R1901S and Q2196H) in the C-terminal cytoplasmic domain of ABCA1. Login to comment

200 of our series (Families 2 and 3), we are tempted to suggest that N1800H might be a recurrent mutation. Login to comment
201 The novel mutations we identified included: (a) one non-sense (R557X) and one frameshift (H160FsX173) mutation, both predicted to encode short peptides presumably devoid of any function; (b) four missense mutations (E284K, Y482C, R1901S and Q2196H) resulting in non-homologous amino acid substitutions.

204 The E284K and the Y482C are located in the first extracellular loop of ABCA1, where they may interfere with the binding to Apo A-I and/or the membrane release of phospholipids, as it has been demonstrated for other mutations (R587W and Q597R) located in the same extracellular domain [40,41].
