Diagnostic and immunological roles of leptin gene rs7799039 polymorphism and cytokines in COVID-19, HCV, and dual infection

Key Points

• Polymorphism in the leptin gene (rs7799039) may influence immune responses in infections.
• Key cytokines associated with leptin may serve as valuable biomarkers for COVID-19 and HCV.
• Analysis reveals significant variations in immune response among individuals with different leptin genotypes.
• The findings may enable more targeted diagnosis and treatment approaches for dual infections.
