Genetic markers in glaucoma.

R David, T Jenkins

    The British Journal of Ophthalmology
    |April 1, 1980
    PubMed
    Summary
    This summary is machine-generated.

    Genetic factors in glaucoma were studied in Black and White patients. No links were found in Black patients, but a significant association between open-angle glaucoma and Rhesus D (+) was identified in White patients.

    Area of Science:

    • Ophthalmology
    • Genetics
    • Immunogenetics

    Background:

    • Glaucoma is a leading cause of irreversible blindness worldwide.
    • Genetic predisposition is a known risk factor for glaucoma.
    • Investigating genetic polymorphisms may reveal disease associations.

    Purpose of the Study:

    • To investigate genetic polymorphisms in relation to glaucoma in Negro and Caucasoid populations.
    • To compare genetic profiles of glaucoma patients with healthy controls.

    Main Methods:

    • Analysis of 18 red cell and serum protein systems in 61 Negro glaucoma patients and 238 controls.
    • Analysis of 14 genetic systems in 31 Caucasoid glaucoma patients and 70 controls.
    • Comparison of allele frequencies between patient and control groups.

    Main Results:

    • No significant association between glaucoma and the studied red cell and serum protein systems was found in the Negro cohort.
    • Populations differed in Rhesus and Duffy blood group systems.
    • A significant association was observed between open-angle glaucoma and Rhesus D (+) phenotype in the Caucasoid cohort.

    Conclusions:

    • Genetic polymorphisms in red cell and serum protein systems are unlikely to be major determinants of glaucoma in Negro populations.
    • Rhesus D (+) antigen may be a risk factor for open-angle glaucoma in Caucasoid individuals.
    • Further research is warranted to elucidate the genetic basis of glaucoma in diverse populations.
