Genetics and public health--evolution, or revolution?

Area of Science:

• Public Health
• Genetics
• Complex Disease Etiology

Background:

• Historically, public health and genetics shared common ground in population health promotion.
• A mid-20th century divergence separated public health from genetics, focusing clinical genetics on single-gene disorders.
• Renewed interest in the causes of complex diseases necessitates collaboration between public health and genetics.

Purpose of the Study:

• To explore the convergence of public health and genetics in addressing complex diseases.
• To review key concerns hindering this collaboration, including fear of eugenics and genetic reductionism.
• To advocate for an evolutionary, multidisciplinary approach to complex disease management.

Main Methods:

• Review of historical trends in public health and genetics.
• Analysis of the aetiology of complex diseases (e.g., heart disease, cancer).
• Identification and discussion of nine major concerns regarding the integration of public health and genetics.

Main Results:

• The convergence of public health and genetics is driven by the need to understand complex diseases.
• Significant concerns exist, including ethical (eugenics, discrimination) and practical (resource allocation, education) issues.
• A multidisciplinary approach is proposed to overcome these challenges.

Conclusions:

• Collaboration between public health and genetics is crucial for tackling complex diseases.
• Addressing ethical and practical concerns is essential for successful integration.
• An evolutionary, multidisciplinary framework offers a path forward for prevention and treatment.
