2 We report identification of 14 previously known and eight novel mutations, namely 3986-3987delC, 876-6del4, 1792InsA, L69H, S158N, Q493L, I530L and E1329Q. Login to comment
67 They included nine missense mutations (L69H, S158N, Q493L, Y517C, V520F, I530L, S549N, E1329Q, and Y1381H), one insertion mutation (1792insA), three splice site mutations (876-6del4, 1525-1G-A, 3120+1G-A), two deletion mutations (1161delC, 3986delC), and 1 nonsense mutation (L218X).

73 Novel Mutations and Phenotypic Features Output prediction scores were assessed for five novel mutations; they were >0.5 for L69H & Q493L and <0.5 for S158N, I530L & E1329Q (Table 3). Login to comment

113 We first identified five of the mutations by ARMS (Delta F508, R117H, R553X, N1303K & G551D) and one by restriction digestion (3849+10kbC-T) and later identified by SSCP eight known (Y517C, V520F, S549N, Y1381H, 1525-1G-A, 3120+1G-A, 1161delC and L218X) and eight previously unreported mutations (L69H, S158N, Q493L, I530L, E1329Q, 876-6del4, 1792insA and 3986-3987delC).

133 Output prediction scores deduced using molecular modeling and a bioinformatics program (http://mmb.pcb.ub.es/PMut/) revealed that among the novel mutations, L69H and Q493L are pathologic but S158N, I530L and E1329Q are neutral. Login to comment
