Some severe COVID-19 cases linked to genetic mutations or antibodies that attack the body

Two new studies offer an explanation for why COVID-19 cases can be so variable. A subset of patients has mutations in key immunity genes; other patients have auto-antibodies that target the same components of the immune system. Both circumstances...
