61 Eight novel missense variations [c.299C > G (p.S100C), c.1724A > G (p.D575G), c.1779C > G (p.F593L), c.3167T > C (p.L1056P), c.3757G > A (p.E1253K), c.4535C > T (p.T1512M), c.5573T > C (p.V1858A), c.5821T > C (p.C1941R)] were introduced into this chimeric construct by site-directed mutagenesis using Stratagene QuikChange XL site-directed mutagenesis kit according to manufacturer`s instructions (La Jolla, CA, USA).

89 In ABCA1, we identified 14 novel and 5 known genetic variations in 16 subjects including one frameshift (p.C978fsX988), 2 splice-site (IVS11-1G > C and IVS48 + 2T > C), 4 nonsense (p.R282X, p.W424X, p.Q1038X, p.Wl747X) and 12 missense variations (p.S100C, p.D575G, p.F593L, p.L1056P, p.E1172D, p.S1181F, p.E1253K, p.C1477R, p.T1512M, p.N1800H, p.V1858A, p.C1941R).

94 From eight novel missense variations identified in our cohort, one is localized in the first transmembrane domain (p.S100C), two in the first large extracellular loop (p.D575G and p.F593L), two in the first Nuclear Binding Domain (p.L1056P and p.E1253K), one in the second large extracellular loop (p.T1512M), one in the extracellular region, close to the plasma membrane (p.V1858A) and one is localized in the C-terminal domain (p.C1941R).

98 Four out of eight mutations were predicted to be probably damaging (p.S100C, p.D575G, p.T1512M, p.C1941R), two as possibly damaging (p.F593L and p.L1056P) and two were described as benign (p.E1253K and p.V1858A) by PolyPhen. Login to comment
110 Fig. 2 shows that the ABCA1-p.S100C, p.D575G, p.F593L, p.L1056P, p.E1253K, p.T1512M, p.C1941R mutant proteins all had a significantly reduced capacity to efflux cholesterol to apo A-I compared to wild-type ABCA1 which is in line with the low HDL cholesterol levels of the individuals in whom the mutations were identified.

154 The ABCA1-p.C1941R mutation showed a marked reduction in cholesterol efflux. Login to comment

39 We included 6 subjects who carried heterozygous mutations in ABCA1: p.Arg587Trp, p.Val618Asp, p.Ser140Ter, p.Pro85Leu, p.Cys1941Arg/c.6402 + 2TNG, 3 subjects with a homozygous mutation in LCAT: p.Thr147Leu/p.Val333Met, p.Thr147Leu and 3 subjects with a heterozygous mutation in LCAT: p.Pro34Gln [19,20].
