What is normal hemoglobin a2?

HbA2 exists in small amounts in all adult humans (1.5-3.1% of all hemoglobin molecules) and is approximately normal in people with sickle-cell disease.

At what age is thalassemia detected?

Most children with moderate to severe thalassemia receive a diagnosis by the time they are 2 years old. People with no symptoms may not realize that they are carriers until they have a child with thalassemia.

What is HB C?

Hemoglobin C is an abnormal type of hemoglobin, the protein in red blood cells that carries oxygen. It is a type of hemoglobinopathy. The disease is caused by a problem with a gene called beta globin. The disease most often occurs in African Americans.

What does it mean if HbA2 is high?

Hb A2 levels tend to increase in conditions that delay nuclear maturation of red cell precursors. These conditions are also associated with increased MCV. The most common cause of this phenomenon is megaloblastic anemia due to folate and/or vitamin B12 deficiency.

What is HbA2 and HbF?

Fetal hemoglobin (HbF) has two alpha and two gamma chains (alpha2 gamma2). Adult hemoglobin A (HbA) has two alpha and two beta chains (alpha2 beta2), whereas hemoglobin A2 (HbA2) has two alpha and two delta chains (alpha2 delta2).

Why does HbA2 increase beta thalassemia?

A smaller component of adult hemoglobin is hemoglobin A2 (HbA2), consisting of two alpha chains and two delta chains. The pathogenesis of beta-thalassemia is two-fold. First, there is decreased hemoglobin synthesis causing anemia and an increase in HbF and HbA2 as there are decreased beta chains for HbA formation.

What is the normal range of thalassemia?

RBC indices show microcytic anemia. Thalassemia major is characterized by reduced Hb level (<7 gdl), mean corpuscolar volume (mcv)> 50 < 70 fl and mean corpuscolar Hb (MCH) > 12< 20 pg. Thalassemia intermedia is characterized by Hb level between 7 and 10 g/dl, MCV between 50 and 80 fl and MCH between 16 and 24 pg.

What does HbA2 mean?

HbA2, composing of two α chains and two δ chains, is a minor component of the hemoglobin present in normal adult red blood cells, accounting for about 2.5% of the total hemoglobin in healthy individuals.

What is HbA2 made of?

Hemoglobin is made up of four subunits: two subunits of alpha-globin and two subunits of another type of globin. Alpha-globin is a component of both fetal hemoglobin, which is active only before birth and in the newborn period, and adult hemoglobin, which is active throughout the rest of life.

How long do thalassemia patients live?

“Most thalassaemia patients would live up to the age of 25 to 30 years. Improved facilities will help them live up to the age of 60,” said Dr Mamata Manglani, head of pediatrics, Sion hospital.

Can thalassemia be cured?

Blood transfusions and chelation do not cure beta thalassemia. A stem cell transplant can cure it, but it is a serious procedure with many risks and won’t benefit everyone with the condition. Doctors and scientist are working on developing gene therapies and other treatments to help people with beta thalassemia.

Is thalassemia a serious disease?

When left untreated, this condition can lead to problems in the liver, heart, and spleen. Infections and heart failure are the most common life-threatening complications of thalassemia in children. Like adults, children with severe thalassemia need frequent blood transfusions to get rid of excess iron in the body.

Does thalassemia minor affect fertility?

Women with thalassemia who require blood transfusions often have a higher rate of infertility. However, some women with the disease are able to become pregnant.

What are the 3 types of hemoglobin?

The other three forms of haemoglobin are present at much lower levels and are:Haemoglobin Gower II (α2ε2) – Composed of two alpha and two epsilon chains.Haemoglobin Portland I (ζ2γ2) – Comprised of two zeta and two gamma polypeptides.Haemoglobin Portland II (ζ2β2) – Made of two zeta and two beta polypeptide chains.

What does low Hemoglobin a2 mean?

Low Hb A2 percentages were found in iron-deficiency anemia, hereditary persistance of fetal hemoglobin, and Hb H disease. In iron-deficiency anemia, the lowest levels of Hb A2 were observed in association with the most severe anemia.
