how you get sickle cell disease?

To be born with sickle cell disease, a child has to inherit a copy of the sickle cell gene from both their parents. This usually happens when both parents are "carriers" of the sickle cell gene, also known as having the sickle cell trait.

Sickle cell anemia is a genetic disease with severe symptoms, including pain and anemia. The disease is caused by a mutated version of the gene that helps make hemoglobin — a protein that carries oxygen in red blood cells.

Sickle cell anemia is caused when a baby gets one sickle cell gene change from each parent. Hemoglobin SC. This condition is caused when a baby gets one sickle cell gene change from one parent and one gene change for hemoglobin C (another abnormal type of hemoglobin) from the other parent.

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.

People who inherit two genes for sickle hemoglobin (one from each parent) have sickle cell disease. With a few exceptions, a child can inherit sickle cell disease only if both parents have one gene for sickle cell hemoglobin. The most common situation in which this occurs is when each parent has one sickle cell gene.

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.

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 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.

- Sickle Cell Disease. When the hemoglobin S gene is inherited from only one parent, and a normal hemoglobin gene—hemoglobin A—is inherited from the other, that person will have sickle cell trait. People who have sickle cell trait are generally healthy.

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.

Pain is a common problem for people with sickle cell disease. It happens when the sickle-shaped red blood cells that cause the condition get stuck in small blood vessels and block blood flow. That can cause a pain episode or crisis to start suddenly, usually in the lower back, arms, legs, chest, and belly.

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.

People who have sickle cell disease can sometimes have vision problems. Blood cells that change shape, or "sickle," can get trapped in blood vessels, blocking the blood flow. When this blockage occurs in the small blood vessels in the inner lining (retina) of the eyes, it can cause vision problems.

Additionally, in individuals with the genetic defect, the painful sickle cell crisis can be precipitated by certain medical and environmental factors including infection, bleeding, exposure to cold weather, leg ulcers, and blockage of the blood vessels.

The disease gets its name because when you have SCD, your red blood cells look like a sickle, which is a C-shaped farm tool. Red blood cells contain a molecule called hemoglobin, which 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.

- Sickle Cell Disease. Sickle cell disease is an inherited disease caused by defects, called mutations, in the beta globin gene that helps make hemoglobin. Normally, hemoglobin in red blood cells takes up oxygen in the lungs and carries it through the arteries to all the cells in the tissues of the body.
