The other three samples where we observed CCR5 homozygous delta32 were in severe outcomes, including patient 15 who had lethal COVID-19, the MODS patient 20 who had Alveolar rhabdomyosarcoma and human betaherpesvirus 7, and the MODS patient 27 who required ECMO and passed away. The gene discussed is CCR5; the disease is COVID-19.
