3 A total of 34 different mutations representing 74.58% of the CF chromosomes were identified, including five novel CFTR mutations: W1098C, P750L, 846delT, 4160insGGGG and 297-1G→A. Login to comment

48 Novel mutations At present, we have identified a total of five novel mutations: two missense mutations (W1098C and P750L), two frameshift mutations (846delT and 4160insGGGG) and one splice site mutation (297-1G→A). Login to comment
49 361 W1098C The missense mutation W1098C was caused by transversion of G to T detected at nucleotide position 3426 in exon 17b of the CFTR gene on the maternal chromosome. Login to comment
52 The patient was diagnosed with the disease at 23 years of age with pancreatic sufficiency, suggesting that W1098C is a mild mutation. Login to comment
70 a W1098C (antisense), b P750L (antisense), c 846delT (antisense), d 4160insGGGG (antisense), e 297-1GA (antisense) three mutations were found in our population during a preliminary screening by SSCP (S549N, 2055del9→A and 1924del7; Orozco et al. 1997); ∆I507 was found during the screening for ∆F508 (Orozco et al. 1994); and three mutations described at least once in Hispanic populations (R1162X, 2869insG; Casals et al. 1997; 3120+ 1G→A; CFGAC 1994). Login to comment
88 W1098C seems to be a mild mutation because the phenotype is mild despite the presence of a severe mutation (R75X) on the other chromosome. Login to comment
