53 She was identified to be the carrier of both alterations because her parents underwent CF screening during a second pregnancy: the mother was found to harbor 621+3 A4G, whereas the father had tested positive for Q552X. Login to comment
93 In conclusion, our data suggest that 621+3 A4G should not be considered a severe CF mutation because of its frequency in the population, because it still allows the synthesis of significant amounts of functional CFTR protein, and the absence of clinical disease in a compound (621+3 A4G/ Q552X) heterozygote individual.

Several mutations were associated with more than one haplotype apparentlyas the result of slippage at one of the microsatellites IVS8CA, IVS17BTA, and IVS17BCA: AF508, G542X, N1303K, R553X, Q552X, 2869insG, L1077P, 7H, and R1162X (Table 3).
