The road to genome-wide association studies

Area of Science:

• Genetics
• Genomics
• Bioinformatics

Background:

• The rapid progress in genome-wide association studies (GWAS) is a culmination of extensive prior research.
• Key conceptual, resource, and technical developments preceded the current era of GWAS.
• The Human Genome Project and subsequent initiatives laid the groundwork for large-scale genetic studies.

Observation:

• Recent GWAS results suggest a sudden surge in genetic discoveries.
• This perceived acceleration masks a long period of foundational scientific development.
• The pre-HapMap project era was critical for assembling the necessary components for GWAS.

Findings:

• The success of modern GWAS is contingent upon earlier, less-publicized advancements.
• The development of genetic concepts, data resources, and analytical techniques was a gradual, cumulative process.
• The period before the HapMap project was instrumental in establishing the infrastructure for large-scale genetic association studies.

Implications:

• Understanding the historical development of GWAS provides context for current genetic research.
• Recognizing the foundational work is essential for appreciating the complexity of genetic discovery.
• Future advancements in genomics and personalized medicine will likely follow similar patterns of incremental development and resource assembly.
