Objective The objective of this study was to detect the relation between macrophage migration inhibitory factor(MIF) −173 G/C genepolymorphism and dilated cardiomyopathy(DCM) in children. Background DCM is the most common cardiomyopathy. Myocardial inflammation is one of the commonest mechanisms in cardiomyopathy. MIF plays an important role in the control of innate immune responses and promotes proinflammatory biological activities; hence, MIF gene polymorphisms may predispose affected hosts to severe inflammatory or infectious disease. Patients and methods This study was conducted on 50patients, 30patients with DCM and 20 age-matched and sex-matched healthy controls. All patients were subjected to history taking, clinical examination, echocardiography, and laboratory measurement of serum sodium and uric acid. Patients and controls were subjected to PCR-restriction fragment length polymorphism to determine MIF 173 G/C polymorphism. Results Our study revealed a significant statistical difference in the distribution of the genotypes and allele frequencies between patients and controls. Studying the relation between different genotypes and echocardiographic parameters(ejection fraction, fractional shortening, left ventricular end-diastolic diameter and left ventricular end-systolic diameter) revealed a highly significant difference between different genotypes among patients. With regard to laboratory characteristics, there was a significantly higher serum sodium level in the CC genotype, while the uric acid level showed no significant difference between different genotypes among patients. Conclusion In our study, we conclude that the CC genotype of MIF gene may be a risk factor for cardiomyopathic patients and that the C allele is associated with severe clinical condition.
