Background and purpose: Due to the high annual birth rate of thalassemia major in our country, its prevention by prenatal diagnosis is of important priority. Gene mutation remains unknown in 10-20% of thalassemia trait people in Iran. In these cases, linkage analysis using polymorphic sites which are located near or within the gene is necessary to follow the mutant or the normal chromosome. Ssp...
introduction: beta thalassemia is the most common inherited bloody disorder, affecting synthesis of the beta globin chain of hemoglobin. the type of β-thalassemia mutation affects on the β-globin chain synthesis that appears as β ° ، β + and β ++ -thalassemia. the presence of xmni polymorphic site at the 5 َ region of the g γ-globin gene affects on the rate of g γ chain synthesis and in some con...
Background: A Thalassemia intermedium is an autosomal recessive disease that from clinical and also genotypic view contains a very heterogeneous group of hemoglobinopathies and severity of disease is placed between thalassemia major and minor. High levels of fetal hemoglobin have a major impact on the severity of this disease, so that increased production of HbF, reduces these veritie...
Background: Molecular genetic factors regulating hemoglobin F (Hb F) expression are important modifiers of the severity of sickle cell anemia (SS). Methods: The prevalence of XmnI polymorphic site, the Gg:Ag ratio and the Hb F level were determined using PCR-RFLP procedure, HPLC and alkaline denaturation method, respectively, in various haplotypes of 52 patients with SS, 18 patients with sickle...
The present study investigated the relationship between microRNA-mediated TRB3 gene and hypertension left ventricular hypertrophy at the molecular level. Polymorphic site in TRB3 gene was identified by direct PCR method, and the correlation between the SNP site and ventricular hypertrophy was determined. MicroRNAs target gene sequence interacting on the TRB3 polymorphic site was screened by bio...
background: molecular genetic factors regulating hemoglobin f (hb f) expression are important modifiers of the severity of sickle cell anemia (ss). methods: the prevalence of xmni polymorphic site, the g g: a g ratio and the hb f level were determined using pcr-rflp procedure, hplc and alkaline denaturation method, respectively, in various haplotypes of 52 patients with ss, 18 patients with s...
