107 A missense mutation within NBD1 (exon 10) was caused by a transversion A to C at nucleotide position 1648 leading to the conservative amino acid change of isoleucine to leucine at position 506. Login to comment
108 The mutation was found in 2 unrelated patients; 1 with the I506L/DF508 genotype (sweat Cl2/103 mmol/liter, PS, and severe lung disease), and the other with the I506L/3659delC genotype (sweat Cl2 80 mmol/liter, PS, and severe lung disease). Login to comment
151 One patient with I506L and 3659delC was diagnosed at a later age and presented with PS, but severe lung disease. Login to comment
172 The remaining missense variants (I506L, N1088D, and R1162Q) can be classified as mild alleles because they are associated with a milder CF phenotypein genotypes with a severe second allele. Login to comment
