Thalassemia is a genetic disorder that involves abnormal haemoglobin formation. The two main categories of thalassemia are alpha and beta thalassemia that are then divided into further subcategories. While some mild forms of thalassemia might even go unnoticed and only cause mild anaemia and iron deficiency problems in patients, other more severe forms of thalassemia can even result in death. I...

AIM Alpha thalassemia is one of the most prevalent disorders worldwide and carrier frequency of the disease is varied in different parts of the world. Although different studies in Iran and Mazandaran province have been carried out to identify different mutations of alpha globin gene among people with low hematological indices, frequencies of these mutations were unknown in general population, ...

Abstract A group of inherited blood defects is known as Thalassemia among the world’s most prevalent hemoglobinopathies. Thalassemias are two types such Alpha and Beta Thalassemia. The cause these gene mutations leading to low levels and/or malfunctioning ? ? globin proteins, respectively. In some cases, one proteins may be completely absent. chains form a fold or pocket for heme (Fe++) attachm...

We report a Korean family case of beta-thalassemia minor and Hb Queens. This is the first case report of Hb Queens in Korea. A 43-year-old male and his four family members had beta-thalassemia minor which is very rare in Korea. Incidentally, an alpha chain variant with a high isoelectric point was also found in two other family members without clinical problems and was finally identified as alp...

Alpha-thalassemia is very common throughout all tropical and subtropical regions of the world. In Southeast Asia and the Mediterranean regions, compound heterozygotes and homozygotes may have anemia that is mild to severe (hemoglobin [Hb] H disease) or lethal (Hb Bart's hydrops fetalis). We have developed a reliable, single-tube multiplex-polymerase chain reaction (PCR) assay for the 6 most fre...

Alpha-thalassemia trait and sickle trait are not commonly considered risk factors of ischemic heart disease. We report the case of a non-atherosclerotic silent myocardial infarction in a 46-year-old woman, carrier of the alpha-thalassemia trait (homozygous deletion of locus -3.7) combined with sickle cell trait. While the patient was included as healthy volunteer for a metabolic study, we perfo...

Background: Beta thalassemia is a common health problem in Iran especially in Northern provinces. Premarital screening for thalassemia is compulsory in Iran and identification of the carriers is based on primary CBC (Cell Blood Count) and hemoglobin electrophoresis. Silent mutations on β-globin gene have borderline or normal hematological indices that cannot be detected in premarital scree...

Alpha Thalassemia is one of the most prevalent disorders worldwide with a [T1] high carrier rate in Mazandaran province (north of Iran). Carriers of --MED double gene deletion are at risk of having a child with hemoglobin  haemoglobin[T2]  H (HbH) disease, if they marry a silent carrier. Co-inheritance of αααAnti3.7 triplication that cannot be detected using hem...

Background: In various cancers, Ganoderic Acid A (GAA), an active triterpenoid derived from Ganoderma Background: Thalassemia refers to a category of inherited disorders resulting from defects in synthesizing one or several chains of hemoglobin (Hb). The present study aimed to determine the frequency of alpha and beta-thalassemia mutations in Kurdistan province, Iran. Materials and Methods: In...

Hemoglobin H (Hb H) disease is the most common form of thalassemia intermedia and has many features that require careful consideration in management. In the majority of cases, Hb H disease results from double heterozygosity for alpha(0)-thalassemia due to deletions that remove both linked alpha-globin genes on chromosome 16, and deletional alpha(+)-thalassemia from single alpha-globin gene dele...
