The haemoglobinopathies and thalassemias represent the most common inherited monogenic disorders in the world. Beta-thalassaemia major is an ongoing public health problem in Malaysia. Prior to 2004, the country had no national policy for screening and registry for thalassemia. In the absence of a national audit, the true figure of the extent of thalassemia in the Malaysian population was largel...

Thalassemia is among the most common genetic disorders worldwide; 4.83 percent of the world’s population carry globin variants, including 1.67 percent of the population who are heterozygous for a -thalassemia and b -thalassemia. In addition, 1.92 percent carry sickle hemoglobin, 0.95 percent carry hemoglobin E, and 0.29 percent carry hemoglobin C. Thus, the worldwide birth rate of people who ar...

Microcytosis is a common hematological finding, usually related to iron deficiency or beta-thalassemia. When both of these conditions are excluded, alpha-thalassemia must be considered in the differential diagnosis. No simple biochemical test is able to diagnose the alpha-thalassemia trait. Using PCR amplification of the breakpoint in deletional forms, and amplification of the alpha 2 gene and ...

Introduction Thalassemia is a group of genetic disorders resulting in the decreased production of globin chains, alpha or beta, leading to the decreased production of hemoglobin (Hb). For the heterozygous state, it can be recognized by the microcytosis of its red blood cell or the decreased mean corpuscular volume (MCV) of less than 80 fL. For alpha-thalassemia-1 or alpha(0)thalassemia traits, ...

BACKGROUND Beta-thalassemia is one of the most common genetic disorders in Thailand. Clinical phenotype ranges from silent carrier to clinically manifested conditions including severe beta-thalassemia major and mild beta-thalassemia intermedia. OBJECTIVE This study aimed to characterize the spectrum of beta-globin gene mutations in pediatric patients who were followed-up in Phramongkutklao Ho...

The frequency of alpha-thalassemia was 3.6% among Turkish newborns in a study that employed globin gene mapping analysis of DnA [4]. In our study, in 13 out of 205 cord blood samples alpha-thalassemia was found 6.3%. There was mistake at incidence so hat we improved with erratum [5]. The incidence of β-thalassemia trait was very high level, the incidence of a-thalassemia trait was also found hi...

Blood (print ISSN 0006-4971, online ISSN 1528-0020), is published weekly by only. The American The J Society ournal of of Hematology VOL 72, NO 4 OCTOBER 1988 THALASSEMIA is an autosomal recessive disease characterized by hypochromic, hemolytic anemia, and dependence on blood transfusions to sustain life.' Even with chelation therapy to remove excess iron stores, the life expectancy in classic ...

The geographical distribution of Alpha and Beta-Thalassemias differ markedly. Alpha-Thalassemia being particularly prevalent in Southeast Asia and Beta-Thalassemia in the Mediterranean basin. Thalassemia syndromes are common in Saudi Arabia: the Beta-Thalassemia genes occur with variable frequency in different regions of Saudi Arabia and both B+ and Bo thalassemia have been reported. Alpha-Thal...

Combined megaloblastic anemia with thalassemia is easily masked because of the loss of macrocytosis. We performed a retrospective study to compare the major parameters in 4 groups of subjects in order to show the characteristics of patients with megaloblastic anemia and thalassemia. Group A comprised 9 patients with megaloblastic anemia and tha-lassemia, group B comprised 10 patients with uncom...
