Abstract Background and Objectives Patients with β-thalassemia major are dependent on regular blood transfusion. Iron overload is the main complication of transfusion which damages vital organs. Hepcidin, a peptide hormone, is the key element of body iron hemostasis. Single nucleotide polymorphisms (SNPs) within the hepcidin gene alter its function and thereby iron status. The aim of this study was to determine the association of three SNPs of rs10421768, rs8101606 and rs66868858 with iron overload in thalassemia patients.
Materials and Methods In this cross-sectional study, one hundred thalassemia patients were recruited. Patient clinical and laboratory data including serum ferritin, liver and heart iron deposition were collected from their files. SNPs genotypes were determined by high resolution melt curve analysis. Association between genotypes and iron overload markers was estimated by chi-square test considering p < 0.05 as statistically significant.
Results Based on serum ferritin > 1000 ng/mL, 72% of patients were iron overloaded and 33% and 63% had abnormal heart and liver iron, respectively. Statistical analysis revealed no relation between SNPs genotype and iron overload.
Conclusions Although we could not find any signification relation, it is probable that the effect of these polymorphisms on iron overload applied through a specific haplotype consisting of several SNPs.
