Hemoglobin E trait is an inherited blood disorder. That means it is passed down through your parent’s genes. It leads to an abnormal form of hemoglobin that may cause mild anemia. It occurs most often in people of Southeast Asian descent.
What is the meaning of E in newborn?
Your baby’s newborn screening test showed that he or she has hemoglobin E trait (this is also referred to as being a “hemoglobin E carrier”). Babies who have hemoglobin E trait are no more likely to get sick than any other baby. They do not need any special medical treatment.
Can hemoglobin E trait donate blood?
A subject with Hb E (HBB: c. 79G > A) trait is asymptomatic and can become a blood donor. However, a blood transfusion from a Hb E trait donor can affect β-thalassemia (β-thal) diagnosis.
Is hemoglobin E bad?
Hemoglobin E trait is caused by a gene defect. This gene defect is passed down from 1 of your parents. It is not a disease. It does not usually cause any health problems.
What is homozygous hemoglobin E?
Homozygous Hemoglobin E (phenotype: FEE in infants and EE in adults) Homozygous hemoglobin E results when the gene for hemoglobin E is inherited from both parents. A mild thalassemia phenotype develops in the first few months of life as the amount of fetal hemoglobin decreases and hemoglobin E increases.
What is HbE beta thalassemia?
Hb E/β-thalassemia, which is the most serious form of Hb E syndromes, is a condition that results from the coinheritance of a β-thalassemia minor trait from one parent and Hb E from the other. It ranges from mild to severe thalassemia of the transfusion-dependent type.
How is hemoglobin E treated?
Treatment for hemoglobin E disease is typically not needed. Folic acid supplements may be prescribed to help the body produce normal red blood cells if mild anemia causes symptoms. Most people do not have any symptoms. People with hemoglobin E disease can expect to lead a normal life.
What is the normal range of Hb E?
Laboratory Findings. The steady-state hemoglobin levels in HbE β thalassemia range widely between the different phenotypes, from 3 g/dl or less to as high as 11 g/dl.
Is hemoglobin E trait a thalassemia?
Hemoglobin E (HbE) is an extremely common structural hemoglobin variant that occurs at high frequencies throughout many Asian countries. It is a β-hemoglobin variant, which is produced at a slightly reduced rate and hence has the phenotype of a mild form of β thalassemia.
What happens if both parents have hemoglobin E?
Hemoglobin E/beta thalassemia disease is a lifelong disease that can cause serious health problems. If both parents have hemoglobin E trait, there is a 25 percent (1 in 4) chance with each pregnancy of having a child with hemoglobin E disease. People with hemoglobin E may have health problems and mild anemia.
What is the life expectancy of someone with thalassemia?
Outlook. The outlook depends on the type of thalassemia. A person with the thalassemia trait has a normal life expectancy. However, heart complications arising from beta thalassemia major can make this condition fatal before the age of 30 years.
What are the 2 disease entities that results from an abnormal hemoglobin?
Inherited hemoglobin disorders fall into two main groups: the structural hemoglobin variants and the thalassemias, which are caused by defective globin production. They all follow a recessive form of inheritance. Those with a single defective globin gene—carriers or heterozygotes—are symptomless.
What are blood cells and where are they found?
Blood cells are the cells which are produced during hematopoiesis and found mainly in the blood. Blood is composed of the blood cells which accounts for 45% of the blood tissue by volume, with the remaining 55% of the volume composed of plasma, the liquid portion of the blood. There are three types of blood cells. They are: 1.
Which blood types can only be given by e antigen?
Individuals with the “E” antigen in their blood can only receive blood transfusions containing type “E negative” blood.
What is the significance of the Big E antigen?
What Is the Big E Antibody? 1 E Antigen. The “Big E” antigen is significant because it can cause increased health risks for certain individuals. 2 Blood Transfusions. Individuals with the “E” antigen in their blood can only receive blood transfusions containing type “E negative” blood. 3 Pregnancy and Childbirth. 4 Treatment and Prevention.
What happens if you give E negative blood?
Blood Transfusions. Individuals with the “E” antigen in their blood can only receive blood transfusions containing type “E negative” blood. Otherwise, the individual may experience a “delayed transfusion reaction.” This results in potentially serious reactions such as allergic responses, infection or hemolysis (degradation of red blood cells).
