  1. If gain of function is done with human hematopoietic stem cell (HSC) engraftment into mice it would explain why the virus was found to attack people with one particular genetic background more compared to other groups. A 2020 genetic association study identified a gene cluster on chromosome 3 as a risk locus for respiratory failure after infection with COVID-19. Match the genetic heritage of the human stem cell donor to those modified mice with the group of humans most vulnerable to the COVID-19 virus, when age and health etc. are accounted for, and you have the smoking gun, proof that the virus was evolved artificially in a lab.
