Functional Genomics of Host-Microbiome Interactions in Humans

Area of Science:

• Microbiology
• Genetics
• Human Health

Background:

• The human microbiome is linked to host phenotypes and complex diseases.
• Genome-wide association studies (GWASs) have identified human genetic variants associated with microbiome variation.
• Understanding host genetic influence on the microbiome is critical for human health research.

Purpose of the Study:

• To summarize findings from GWASs on host genetic associations with the microbiome.
• To illustrate mechanisms of host genetic regulation of microbiome composition.
• To emphasize the importance of functional genomics in elucidating host-microbiome interactions.

Main Methods:

• Review of recent genome-wide association studies (GWASs).
• Discussion of potential regulatory mechanisms.
• Highlighting experimental, functional, and computational genomics methodologies.

Main Results:

• GWASs have uncovered human genetic variants associated with microbiome variation.
• Host genetic variation can modulate microbiome composition.
• Functional genomics approaches are key to understanding causal interactions.

Conclusions:

• Host genetic variation plays a significant role in shaping the human microbiome.
• Functional genomics is essential for a mechanistic understanding of host-microbiome interactions in disease.
• Integrating genomics approaches can explain how host genetics influence microbiome effects on health.
