9 Three of these mutations (R117H, Y301C, and E527G) are thought to be disease causing in CF or in CBAVD, since they determine the substitution of an amino acid in evolutionarily conserved residues and therefore are tentatively classified, on the basis of the Cystic Fibrosis Genetic Analysis Consortium (CFGAC) database, as "mutations"; the other four mutations (1716 G/A, 2622ϩ14 G/A, 3041-71 G/C, and 4002 A/ G) are not believed to be disease causing in CF and CBAVD, either because they do not determine any amino acid substitutions (in the case of 1716 G/A and 4002 A/ G) or because they occur in noncoding regions that, as determined by sequence-analysis software, produce no apparent alteration (in the case of 2622ϩ14 G/A and 3041-71 G/C) and therefore are tentatively classified, on the basis of the CFGAC database, as CF "polymorphisms."
