Association of macrophage migration inhibitory factor promoter polymorphism -173G/C with susceptibility to childhood asthma.

Introduction: Macrophage migration inhibitory factor (MIF) is a proinflammatory cytokine that plays an important role in the pathogenesis of asthma. Polymorphisms associated with inflammatory diseases exist in the promoter region of MIF, which alter its expression. We aimed to study the association of MIF promoter polymorphism -173G/C with childhood asthma.
