background: β-thalassemia as a hereditary disease is defined as defective synthesis of   β-globin chains, resulting in erythropoiesis abnormalities and severe anemia. different studies have shown that cytokines and cytokine gene polymorphisms play a major role in the pathogenesis of   β-thalassemia. single nucleotide polymorphisms (snps) within the promoter region or other regulatory sequences ...

background: ovarian cancer is a relatively common cancer among postmenopausal women. nowadays, there is controversy about immunotherapy of ovarian cancer patients with interleukins such as interferon to reach better out come in prognosis of patients under chemotherapy. ctla-4 is a gene, which has an important role in homeostasis and regulation of immune response. inhibitory nature of ctla-4 is ...

Background: Multiple Sclerosis (MS), the most common demyelinating disease of the CNS, is immunologically mediated in genetically susceptible individuals. Receptors for the Fc fragment of IgG (FcγR) might induce inflammatory responses through linking the humoral and cellular immune responses by targeting immune complexes to effector cells. Polymorphisms in some FcγR genes are associated with va...

Objective: NRG1 is one of the genes that was reported to have susceptibility alleles effecting phenotype schizophrenia. There are many SNPs (single nucleotide polymorphisms) located in gene with suspected which were associated In this study, we investigated potential associations between schizophrenia and polymorphisms rs4560751 rs3802160. Material Methods: We collected DNA samples 96 patients ...
