The mammalian gut is colonized by trillions of microorganisms collectively called the microbiome. It is increasingly clear that this microbiome has a critical role of in many aspects of health including metabolism and immunity. While environmental factors such as diet and medications have been shown to influence the microbiome composition, the role of host genetics has only recently emerged in human studies and animal models. In this review, we summarize the current state of microbiome research with an emphasis on the effect of host genetics on the gut microbiome composition. We focus particularly on genetic determinants of the host immune system that help shape the gut microbiome and discuss avenues for future research.
