what chromosome is sickle found on?
16805
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. Red blood cells with normal hemoglobin (hemoglobin-A) are smooth and round and glide through blood vessels.

A genetic disease Sickle cell anemia results from a mutation in a gene called HBB, which contains the blueprint for cells to make part of a protein called hemoglobin. The hemoglobin protein is made up of two alpha chains and two beta chains. Each chain includes an iron-containing “heme” portion.

Types of Sickle Cell Disease. 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.

Sickle cell anemia is an inherited red blood cell disorder in which there aren't enough healthy red blood cells to carry oxygen throughout your body. Normally, the flexible, round red blood cells move easily through blood vessels. In sickle cell anemia, the red blood are shaped like sickles or crescent moons.

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.

The altered form of hemoglobin that causes sickle-cell anemia is inherited as a codominant trait. Specifically, heterozygous (Ss) individuals express both normal and sickle hemoglobin, so they have a mixture of normal and sickle red blood cells.

Sickle cell disease is a group of inherited red blood cell disorders. People who have sickle cell disease have an abnormal protein in their red blood cells. In the United States, most people who have sickle cell disease are of African ancestry, but the condition is also common in people with a Hispanic background.

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. Also known as Sickle Cell Anemia, Hemoglobin S or SS disease, Sickling disorder due to hemoglobin S. Leer en español. Sickle cell disease is a group of inherited red blood cell disorders. People who have sickle cell disease have an abnormal protein in their red blood cells.

On blood group and sickle cell disease, the study showed that blood group O is most commonly associated with genotype SS (SCD), followed by blood group B, then A group and the least prevalence is AB.

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).

You are born with sickle cell hemoglobin and it is present for life. If you inherit only one sickle gene, you have sickle cell trait and will not develop the disease. If you inherit two sickle cell genes, you have sickle cell anemia.

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).

Sickle cell trait is an inherited blood disorder that affects 1 million to 3 million Americans and 8 to 10 percent of African Americans. Sickle cell trait can also affect Hispanics, South Asians, Caucasians from southern Europe, and people from Middle Eastern countries.

Abstract. Sickle cell anemia (SCA) is a disease caused by production of abnormal hemoglobin, which binds with other abnormal hemoglobin molecules within the red blood cell to cause rigid deformation of the cell.
148044
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 disease have atypical hemoglobin molecules called hemoglobin S, which can distort red blood cells into a sickle, or crescent, shape.

Most people affected are of African or African-Caribbean origin, although the sickle gene is found in all ethnic groups. It is estimated that there are between 12,500 and 15,000 people with sickle cell disease in the UK. The prevalence of the disease is increasing because of immigration into the UK and new births.
