Why epistasis is important for tackling complex human disease genetics

Area of Science:

• Genetics
• Human Disease
• Bioinformatics

Background:

• Epistasis, the interaction between genes, is often overlooked in complex human disease research.
• Current understanding of genetic architecture may be incomplete due to underestimating epistatic effects.

Purpose of the Study:

• To challenge the dismissal of epistasis in human disease genetics.
• To explain the importance of exploring epistasis for disease prediction and understanding.

Main Methods:

• Review of existing literature on epistasis and complex diseases.
• Conceptual analysis of the role of gene-gene interactions in genetic architecture.

Main Results:

• The view that epistasis plays a minor role is based on a misconception.
• Epistatic interactions are fundamental to the genetic basis of complex diseases.

Conclusions:

• Exploring epistasis is essential for advancing our understanding of complex human diseases.
• Accurate disease prediction models must incorporate epistatic effects.
• Revisiting the role of epistasis is critical for a comprehensive genetic architecture framework.
