One gene variant could be a shield against severe COVID-19 lung damage

Researchers identify a specific genetic variant, rs2204985, linked to less severe lung involvement and a stronger immune response in COVID-19 patients with severe pneumonia. The study suggests that understanding this genetic marker could help identify high-risk individuals and enhance strategies for prevention and treatment.
