what chromosome does sickle cell disease affect?
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.

Sickle cell disease (SCD), or sickle cell anemia, is a group of genetic conditions, resulting from the inheritance of a mutated form of the gene coding for the β globulin chain of the hemoglobin molecule, which causes malformation of red blood cells (RBCs) in their deoxygenated state.

Sickle cell disease effects fertility in both males and females, but more often in males than in females. This is likely because of the delay in puberty (sexual maturation), priapism, and primary gonad dysfunction.

Sickle cell disease (SCD) is a blood disorder that a child is born with. It's passed down through a parent's genes. Children with SCD make an abnormal type of hemoglobin. This is the protein in red blood cells that carries oxygen to all parts of the body. With SCD, the body organs and tissues don't get enough oxygen.

Sickle cell disease is an inherited blood disorder marked by defective hemoglobin. It inhibits the ability of hemoglobin in red blood cells to carry oxygen. Sickle cells tend to stick together, blocking small blood vessels causing painful and damaging complications.

While beta thalassemia is caused by a defect in the beta-globin gene, controlling the production of the beta-globin chains of hemoglobin, sickle cell disease is caused by a defect in hemoglobin itself with the presence of abnormal hemoglobin S.

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.

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.
882946
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.

Any and all major organs are affected by sickle cell disease. The liver, heart, kidneys, gallbladder, eyes, bones, and joints can suffer damage from the abnormal function of the sickle cells and their inability to flow through the small blood vessels correctly. Problems may include the following: Increased infections.

Types of SCD People who have this form of SCD inherit two sickle cell genes (“S”), one from each parent. This is commonly called sickle cell anemia and is usually the most severe form of the disease.

['People of African descent, including African-Americans (among whom 1 in 12 carries a sickle cell gene)', 'Hispanic-Americans from Central and South America.', 'People of Middle Eastern, Asian, Indian, and Mediterranean descent.']

Having sickle cell disease alone does not affect learning ability, but the complications of the disease may cause learning problems. Students may require extra help and encouragement when illness interferes with school. Fatigue due to anemia and sleep disturbances may be present.

Sickle cell disease is the name for a group of inherited health conditions that affect the red blood cells. The most serious type is called sickle cell anaemia. Sickle cell disease is particularly common in people with an African or Caribbean family background.

Sickle cell disease affects how your body makes red blood cells, which carry oxygen throughout your body. Red blood cells are normally flat, flexible discs. But if you have sickle cell disease, your body makes red blood cells that are stiff and shaped like a crescent, or a sickle.

Sickle Cell Disease and Sickle Cell Anaemia. Sickle cell disease (SCD) is a serious, inherited condition affecting the blood and various organs in the body. It affects the red blood cells, causing episodes of sickling, which produce episodes of pain and other symptoms.

How sickle cell disease is inherited. Genes come in pairs. You inherit 1 set from your mother and 1 set from your father. To be born with sickle cell disease, a child has to inherit a copy of the sickle cell gene from both their parents.
