what causes sickle cell diseases?

Sickle cell anemia is caused by a mutation in the gene that tells your body to make the iron-rich compound that makes blood red and enables red blood cells to carry oxygen from your lungs throughout your body (hemoglobin).

Sickle cell disease (SCD) is a group of inherited red blood cell disorders. If you have SCD, there is a problem with your hemoglobin. Hemoglobin is a protein in red blood cells that carries oxygen throughout the body. With SCD, the hemoglobin forms into stiff rods within the red blood cells.

Sickle-Cell Disease Genetics. Sickle-cell disease is caused by a gene mutation that leads to the production of Sickle haemoglobin, which affects the function of the red blood cells in the body. This mutation is inherited from the parents of an individual in an autosomal recessive pattern.

Children with sickle cell disease usually grow and develop more slowly, even reaching puberty later than their peers. This growth delay is caused by having fewer red blood cells. Adults with sickle cell disease are also typically shorter and thinner than the general population.

Sickle cell disease affects millions of people worldwide. It is most common among people whose ancestors come from Africa; Mediterranean countries such as Greece, Turkey, and Italy; the Arabian Peninsula; India; and Spanish-speaking regions in South America, Central America, and parts of the Caribbean.

There are several types of sickle cell disease. The most common are: Sickle Cell Anemia (SS), Sickle Hemoglobin-C Disease (SC), Sickle Beta-Plus Thalassemia and Sickle Beta-Zero Thalassemia.

A sickle cell test is a blood test done to check for sickle cell trait or sickle cell disease. Sickle cell disease is an inherited blood disease that causes red blood cells to be deformed (sickle-shaped).

SCD is a well-known genetic disorder that results in dramatic alteration and function of red blood cells (RBCs). Sickle RBCs can also obstruct the vasculature; activate leukocytes, platelets, and endothelial cells; and exacerbate inflammation.

What is sickle cell disease (anemia)? A blood disorder in which the red blood cells are sickle shaped and are unable to move through blood vessels smoothly. They have a shorter life span b/c they are more fragile, causing a deficiency in hemoglobin- the protein in RBCs that carries oxygen throughout the body.

Sickle cell disease is caused by a mutation in the hemoglobin-Beta gene found on chromosome 11. Hemoglobin transports oxygen from the lungs to other parts of the body.

Causes. Sickle cell anemia is caused by a mutation in the gene that tells your body to make the iron-rich compound that makes blood red and enables red blood cells to carry oxygen from your lungs throughout your body (hemoglobin).
247914
Sickle cell disease and thalassemia are genetic disorders caused by errors in the genes for hemoglobin, a substance composed of a protein ("globin") plus an iron molecule ("heme") that is responsible for carrying oxygen within the red blood cell.

Although many diseases and complications can affect and arise in the Lymph system, those with Sickle Cell Disease typically suffer from those associated with the spleen. The Spleen: Acts as a filter where old red blood cells are recycled. Also the spleen produces white blood cells.

The leading causes of death in sickle cell diseases (SCD) are infection, pain episodes, acute chest syndrome and stroke [1, 2]. Death can be sudden and unexpected in sickle cell anaemia [1]. Vaso-occlusive crisis is one of the commonest presentations and a leading cause of death [3].

Sickle cell disease is caused by what mutation? Mutation in the hemoglobin beta (HBB) gene, leading to a single change in amino acid sequence.

Description. Sickle cell disease is a group of disorders that affects hemoglobin, the molecule in red blood cells that delivers oxygen to cells throughout the body. People with this disorder have atypical hemoglobin molecules called hemoglobin S, which can distort red blood cells into a sickle, or crescent, shape.
