FOXP4 and COVID-19: For example, a recent large genome-wide association analysis demonstrated that the Forkhead Box P4 gene (FOXP4) has a significant association to long COVID.5 Further, there have been over 20 genetic variants identified with significant associations to COVID-19 contraction and hospitalization.6 Given these findings, it is plausible that these genetic variants may also have an effect on a person’s risk to have long lasting side effects after contracting COVID-19.
