Alpha thalassemia


L' alfa-talassemia (α-talassemia) è un tipo di talassemia che coinvolge i geni che codificano per le emoglobine HbA e HbA 2.. La malattia è caratterizzata dalla compromissione della produzione di una, due, tre o addirittura tutte e quattro le catene α dell' emoglobina, che correla direttamente con la gravità clinica della malattia Alpha thalassemia occurs when some or all of the 4 genes that make hemoglobin (the alpha-globin genes) are missing or damaged. There are 4 types of alpha thalassemia: Alpha thalassemia silent carrier. One gene is missing or damaged, and the other 3 are normal

Alpha Thalassemia Johns Hopkins Medicin

  1. Alpha-thalassemia is a blood disorder that reduces the body's production of hemoglobin. Affected people have anemia, which can cause pale skin, weakness, fatigue, and more serious complications. Two types of alpha-thalassemia can cause health problems: the more severe type is known as Hb Bart syndrome; the milder form is called HbH disease
  2. La prima forma di talassemia, quella più comune in Nord Africa, è comunemente conosciuta come Alfa Talassemia. Viene causata dalla mutazione in almeno una delle quattro copie di geni che si occupano di codificare la catena alfa. Esistono quattro forme di alfa talassemia, vediamo quali sono
  3. There are different types of thalassaemia, which can be divided into alpha and beta thalassaemias. Beta thalassaemia major is the most severe type. Other types include beta thalassaemia intermedia, alpha thalassaemia major and haemoglobin H disease. It's also possible to be a carrier of thalassaemia, also known as having the thalassaemia trait
  4. La talassemia è una malattia del sangue geneticamente trasmessa, in cui l'organismo sintetizza un'anomala forma di emoglobina. Come noto ai più, l'emoglobina è una proteina contenuta nei globuli rossi, indispensabile per il trasporto dell'ossigeno nel sangue
  5. Thalassemia is an inherited blood disorder in which the body makes abnormally low levels of haemoglobin. Due to low haemoglobin, there is less number of Red blood cells in the blood. It is a genetic disorder and if your parents have it then you have increased chances of having Thalassemia. 8th May is observed as World Thalassemia day
  6. Alpha thalassemia occurs when the body can't make alpha globin. In order to make alpha globin, you need to have four genes, two from each parent. This type of thalassemia also has two serious..

Alpha Thalassemia: Read About This Trait - MedicineNe

Alpha thalassemia happens when one or more of the genes that control the making of alpha globins is absent or defective. It can cause anemia ranging from mild to severe and is most commonly found in people of African, Middle Eastern, Chinese, Southeast Asian, and, occasionally, Mediterranean descent In thalassemia, the production of either the alpha or beta chains are reduced, resulting in either alpha-thalassemia or beta-thalassemia. In alpha-thalassemia, the severity of thalassemia you have depends on the number of gene mutations you inherit from your parents. The more mutated genes, the more severe your thalassemia

The alpha thalassemia (α-thalassemia) syndromes are a group of hereditary anemias of varying clinical severity. They are characterized by reduced or absent production of 1 or more of the globin.. Alpha thalassemia is an inherited condition and requires both parents to be carriers. A person without alpha thalassemia should have four alpha globin genes. The risk of having a child with alpha thalassemia disease is dependent on the status of the parents. The trans form of alpha thalassemia minor is more common in people of African descent

Alpha-Thalassemia: Causes, symptoms, types, diagnosis and

Alpha-thalassemias result in decreased alpha-globin production; therefore, fewer alpha-globin chains are produced, resulting in an excess of β chains in adults and excess γ chains in newborns. The excess β chains form unstable tetramers (called hemoglobin H or HbH of 4 beta chains), which have abnormal oxygen dissociation curves Clinical background: Alpha-thalassaemia is the most common inherited haemoglobin disorder in the world. It is characterised by a reduced production of the alpha-globin chain, resulting in a decrease in the total amount of haemoglobin

Thalassemia patients, especially young adults/adults, have a chronic condition which may be associated with several co-morbidities linked to the underlying disease as well as complications of chronic transfusions, including heart failure, pulmonary hypertension, and diabetes Alpha-thalassemia is a form of thalassemia involving the genes HBA1 and HBA2. Alpha-thalassemia is due to impaired production of alpha chains from 1,2,3, or all 4 of the alpha globin genes, leading to a relative excess of beta globin chains. The degree of impairment is based on which clinical phenotype is present (how many genes are affected)

Alpha thalassemia is a type of thalassemia that is inherited (passed down through families). It is a blood disorder that reduces how well the body produces healthy red blood cells and normal hemoglobin. Hemoglobin is an iron-rich protein in red blood cells that carries oxygen to cells throughout the body Alpha-thalassemia (α-thalassemia) has two clinically significant forms: hemoglobin Bart hydrops fetalis (Hb Bart) syndrome, caused by deletion of all four α-globin genes; and hemoglobin H (HbH) disease, most frequently caused by deletion of three α-globin genes. Hb Bart syndrome, the more severe form, is characterized by fetal onset of generalized edema, pleural and pericardial effusions. Alpha thalassemia is an inherited blood disease that affects the production of hemoglobin and the ability of red blood cells to provide the body with enough oxygen. Changes in any of four alpha globin genes, which make an important protein inside a red blood cell called alpha globin,.

Alpha-Thalassemia - PubMe

A number sign (#) is used with this entry because of evidence that alpha-thalassemia is caused by mutations in the alpha-globin genes (HBA1, 141800; HBA2, 141850). Sequences 30 to 50 kb upstream from the alpha-globin gene cluster, referred to as the locus control region alpha (LCRA; 152422), have been found to be deleted in cases of alpha-thalassemia with structurally intact alpha-globin genes If one of the four copies of the alpha globin gene is not present in an individual they will not have any symptoms because they still make enough alpha globin. This individual is often referred to as a silent carrier Alpha Thalassemia Trait Edit. If two of the genes are not present than the person is said to have the alpha thalassemia trait

Alpha Thalassemia - Thalassemia

Alpha thalassemia carrier - two alpha chain genes are deleted, either: Both from the same #16 chromosome, called a cis deletion One from both #16 chromosomes, called a trans deletion When parents are carriers of the cis deletion, there is a one in four, or 25 percent, chance with each pregnancy, to have a baby with alpha thal major [Alpha-thalassemia]. [Article in French] Peltier JY(1), Sayada C, Girot R. Author information: (1)Laboratoire d'hématologie, hôpital Tenon, Paris, France. alpha-Thalassaemias are probably the most common genetic disorder worldwide. alpha-Thalassaemias are haemolytic anaemias resulting from inherited deficient synthesis of alpha-globin chains Key Difference - Alpha vs Beta Thalassemia Thalassemia is a heterogeneous group of disorders caused by inherited mutations that decrease the synthesis of either alpha or beta globin chains, leading to anaemia, tissue hypoxia and red cell hemolysis related to the imbalance in globin chain synthesis. There are two major forms of thalassemia as alpha thalassemia and beta thalassemia 500.000 Prodotti di Elettronica, Automazione e Manutenzione

The most severe form of alpha thalassemia is alpha thalassemia major or Bart's hydrops fetalis. This disease occurs when all four alpha genes are missing. It can be successfully treated provided the pregnancy is anticipated or the diagnosis is made early with ultrasound and genetic testing of the fetus. Several patients have been cured with bone marrow transplants after birth Alpha thalassemia is an inherited blood disorder that affects the way hemoglobin (the molecule that carries iron and oxygen in the blood) is produced. It leads to a decrease in overall hemoglobin levels, with the characteristic signs and symptoms of anemia. Signs and symptoms of alpha thalassemia are those of other types of anemia and includ hemoglobin H (HbH) disease (also called alpha-thalassemia intermedia) - 1 functional copy of alpha globin hemoglobin Bart hydrops fetalis syndrome (also called alpha-thalassemia major, Hb Bart diseases, or homozygous alpha thalassemia) - 0 functional copies of alpha globi Abstract and Figures Background: The frequency of alpha thalassemia trait is about 40% in the Kuwaiti population, but there has been no comprehensive study of the prevalent alleles. This is a.. There are at least 4 different and distinct alpha-thalassemias: silent carrier (1 affected alpha-globin gene), alpha-thalassemia trait (2 affected alpha-globin genes), Hb H disease (typically 3 affected alpha-globin genes), and Hb Bart hydrops fetalis syndrome (typically deletion of all 4 alpha-g..

Alpha-thalassemia Genetic and Rare Diseases Information

Alpha thalassemia is an inherited blood disorder. This means it is passed down through the parent's genes. It may cause anemia in their children. Anemia is low numbers of red blood cells or low hemoglobin level Alpha thalassemia is a group of inherited blood disorders characterized by reduced or absent production of α-globin subunits, resulting in low levels of hemoglobin, decreased mean corpuscular volume (MCV) and decreased mean corpuscular hemoglobin (MCH Based on the defective globin chain, they are classified as either alpha or beta subtypes. Thalassemias are generally more frequent in areas where malaria is endemic; alpha thalassemias occur most commonly in patients of Asian or African origin, whereas beta thalassemias are predominant in patients of Mediterranean descent Alpha thalassemia is one of the most widespread genetic diseases worldwide, with frequencies of the carrier state reaching up to 80-90% in some areas [ 1 ] Alpha thalassemia intermedia, or hemoglobin H disease, causes hemolytic anemia. Alpha thalassemia major with hemoglobin Bart's usually results in fatal hydrops fetalis. Beta thalassemia major..

  1. Alpha-Thalassemia, also referred to as α-Thalassemia is a type of Thalassemia that is caused by a deficiency of the alpha globin protein. Impaired 1, 2, 3, or 4 alpha globin chain productions can lead to a comparative excess of the beta globin chains
  2. Alpha thalassemia is a general term for a group of inherited blood disorders characterized by reduced or absent production of alpha-globin subunits, resulting in low levels of hemoglobin that is otherwise fully functional. Hemoglobin is found in red blood cells; it is the red, iron-rich, oxygen-carrying pigment of the blood
  3. Alpha-thalassemia is inherited in an autosomal recessive manner. Normally two alpha hemoglobin genes are inherited from each parent, one HBA1 gene and one HBA2 gene, for a total of four alpha hemoglobin genes. If a parent is missing one or two of these genes, then their children are at risk of having alpha-thalassemia

Alpha Thalassemia . Alpha thalassemia is a result of either mutation or depletion of one or several alpha -globin genetic factor copies. It is important to note that alpha-globin production decreases due to mutation. The bigger the number of genes affected, the low alpha-globin the body will produce Alpha thalassemia is caused by defects in the genes that control hemoglobin production. There are three types: Alpha thalassemia major (Hb Bart syndrome). This is a very serious form that develops before birth. It causes hydrops fetalis. This is a condition in which the body has too much fluid and other serious problems

Thalassemia: Causes, Symptoms, Diagnosis, and Treatmen

Alpha-thalassemia can be diagnosed by blood analysis. Genetic testing can also be performed to determine the exact changes to the genes involved, HBA1 and HBA2. Blood testing involves analysis of the size, shape, color and number of red blood cells and is called a complete blood count, or CBC Alpha thalassemia: Introduction. Alpha thalassemia: Thalassemia is an inherited blood disorder characterized by abnormal synthesis of hemoglobin. Hemoglobin consists of two main protein chains called alpha and beta. Alpha thalassemia involves defects in one or more of the four genes required to make each ? protein chain In alpha-thalassaemia trait, the Hb does not usually decline below 90 g/L (9 g/dL) and therefore intervention is not typically required.

Alpha-thalassemia (α-thalassemia, α-thalassaemia) is a form of thalassemia involving the genes HBA1 and HBA2. Alpha-thalassemia is due to impaired production of alpha chains from 1, 2, 3, or all 4 of the alpha globin genes, leading to a relative excess of beta globin chains. The degree of impairment is based on which clinical phenotype is present (how many genes are affected) Alpha thalassemia is the condition where there is a reduced formation of alpha polypeptide chains because of an absence of alpha genes. There are two forms of alpha thalassemia depending on what genes are missing. Alpha + is when only one gene is missing from chromosome 16, while alpha 0 is when both genes are lacking from the same chromosome. Carriers of alpha and beta thalassemia traits, get married or not?
