The COVID-19 Host Genetics Initiative (HGI) represents a consortium of over 3000 scientists from over 54 countries working collaboratively to share data, ideas, recruit patients and disseminate our findings. For a primer on our study design, please read our inaugural blog post. Our research is iterative, and we summarize our new results via blog posts and on the results section of our website. Finally, if any vocabulary here is unfamiliar, please send us an email at [email protected]—we’d be happy to update the information here to provide more clarity. You can also check out our FAQ and take a look at this resource to review the basics of genetics.
