  • Title: Some clinical implications of recombinant DNA technology with emphasis on prenatal diagnosis of hemoglobinopathies.
    Author: Anderson A.
    Journal: Clin Biochem; 1984 Apr; 17(2):112-9. PubMed ID: 6329548.
    Abstract:
    Recombinant DNA technology has made possible remarkable advances in understanding the molecular genetics of human and other eucaryotic cells. This technology also has clinical applications, some of which may soon involve clinical laboratories. Restriction endonucleases and cloned DNA probes permit the direct analysis of cellular DNA to detect sequence abnormalities associated with particular genetic disorders. Use of this approach in the antenatal diagnosis of hemoglobinopathies is now possible on a routine basis. The principles behind the methods are quite general and may be applied to other hereditary diseases once suitable DNA probes become available. The same approach may be used to detect carriers of recessive gene defects and so improve genetic counselling. Other clinically related applications of recombinant DNA technology include the production of antigens for vaccine preparation and of specific human proteins (e.g. interferon and human growth hormone) for therapeutic use, as well as the use of nucleic acid hybridization for identification of microbial pathogens. It seems likely that recombinant DNA technology will, in the future, play an increasingly important role in the diagnosis, prevention and treatment of human disease.
