  • Title: Molecular screening of cystic fibrosis patients.
    Author: Fellowes AP, Murphy JM, Wesley AW, Dawson KP, George PM.
    Journal: N Z Med J; 1991 Oct 09; 104(921):415-6. PubMed ID: 1923090.
    Abstract:
    A method for the direct direction of the delta F508 mutation in the cystic fibrosis gene has been developed and applied to the analysis of over 280 individuals including 104 individuals with cystic fibrosis. This technique allows the rapid analysis of DNA from whole blood, Guthrie card blood spots, and the antenatal diagnosis of cystic fibrosis from chorionic villus biopsy samples. Based on these analyses, the delta F508 mutation is found in 77.88% of cystic fibrosis chromosomes in New Zealand cystic fibrosis patients. Thus this test can be used to establish a direct DNA diagnosis in over 60% of cystic fibrosis patients. Approximately a further 30% are heterozygous for this mutation.
