74 Three patients were heterozygous for ABCA1 mutations G1216V, C1477F, and N1800H that have been reported to be associated with low HDL cholesterol levels [17-19]. Login to comment
88 HDL cholesterol levels in individuals carrying a pathogenic mutation in the ABCA1 or apoA-I genes Both the two identified apoA-I mutations and the following ABCA1 mutations were considered pathogenic: the nonsense mutation (C1429X); the two splice-site mutations (IVS4 +1, G NA and IVS32+1, GNA ); novel mutations R282Q, M636V, C887F, L1244Q, and V1674I; and mutations previously reported to be associated with low HDL cholesterol levels (G1216V, C1477F and N1800H).

116 This has been shown for mutations G1216V, C1477F, and N1800H [11,17], thereby explaining the mechanism for the low HDL cholesterol levels in carriers of these mutations. Login to comment

47 In ABCA1, a total of 19 nonsynonymous coding sequence variants; some of these we reported previously.22 Of these, 9 sequence variants were common polymorphisms (ie, reported in the literature as common or of similar prevalence in control subjects): P85L, P85A, R219K, V399A, V771M, V825I, I883M, E1172D, R1587K.14,32-35 Another 5 sequence variants, identified here, were previously reported to be disease causing: W590L (reported as W590S)14; C1477F (reported as C1477R)13; S1731C (only found in French-Canadian populations)36; N1800H32; and 1851X.37 Five sequence variants were novel: K199F, H551D, R965C, E1386Q, and D1706N.

49 Eight subjects with sequence variants in ABCA1 had defective cholesterol efflux (measured in repeated assays cholesterol-loaded monocyte-derived macrophage [MDMs]), and these ABCA1 sequence variants were tested in an in vitro expression system for cholesterol efflux activity.38 ABCA1 proteins containing the sequence variants W590L, C1477F, D1706N, S1731C, or N1800H were all found to have significantly impaired cholesterol efflux, whereas the H551D and E1386Q variants had very minor, if any, effects on cholesterol transport (Figure 1A).
