    Area of Science:

    • Genetics
    • Epidemiology
    • Biostatistics

    Background:

    • Understanding genetic associations with diseases is crucial for diagnosis and treatment.
    • Previous models may have limitations in handling multiple alleles or complex genetic architectures.

    Purpose of the Study:

    • To develop a flexible statistical model for analyzing disease-marker associations.
    • To introduce a goodness-of-fit test for evaluating disease susceptibility models.
    • To apply the developed methods to a real-world dataset for type I diabetes.

    Main Methods:

    • A general statistical model was formulated for disease-marker association analysis.
    • The model accommodates an arbitrary number of marker and disease susceptibility alleles.
    • A goodness-of-fit testing procedure was developed for genotype distributions.
