Analyzing complex genetic and environmental factors simultaneously is crucial for understanding diseases like myocardial infarction. This study introduces a new statistical framework to handle these multi-factor causal relationships effectively.

Area of Science:

  • Genetics
  • Epidemiology
  • Bioinformatics

Background:

  • Analyzing genome-wide data for multi-factor causal relationships presents significant challenges.
  • Existing methods often struggle to simultaneously assess genetic polymorphisms and environmental influences.

Purpose of the Study:

  • To propose a novel statistical framework for association studies.
  • To simultaneously analyze genetic polymorphisms and epigenetic information, including environmental factors.

Main Methods:

  • Development of a framework using the maximum likelihood method.
  • Application of the framework to genotyped data from myocardial infarction (MI) patients.

Main Results:

  • The proposed framework successfully integrates genetic and environmental data.
