How do you get sickle cell gene?
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. This usually happens when both parents are “carriers” of the sickle cell gene, also known as having the sickle cell trait.
Can a white person get sickle cell?
Yes, they can. Sickle cell disease can affect people of ANY race or ethnicity. Sickle cell disease, an inherited disorder of the red blood cells, is more common in African Americans in the U.S. compared to other ethnicities—occurring in approximately 1 in 365 African Americans.
What causes a person to get sickle cell disease?
Causes Sickle cell disease is caused by inheriting the sickle cell gene. It’s not caused by anything the parents did before or during the pregnancy and you cannot catch it from someone who has it. Genes come in pairs. You inherit 1 set from your mother and 1 set from your father.
Can a person with sickle cell anemia have more than one allele?
The sickle cell anemia trait is found on a recessive allele of the hemoglobin gene. This means that you must have two copies of the recessive allele — one from your mother and one from your father — to have the condition. People who have one dominant and one recessive copy of the allele won’t have sickle cell anemia.
Where is the gene that causes sickle cell anemia located?
The gene that can cause Sickle Cell Anemia is called HBB and is located in Chromosome 11. HBB helps in the creation of hemoglobin in the body.
Are there any negative effects of sickle cell allele?
There are negative effects at the whole organism level. Under conditions such as high elevation and intense exercise, a carrier of the sickle cell allele may occasionally show symptoms such as pain and fatigue. There are positive effects at the whole organism level.
What causes a person to be born with sickle cell disease?
The cause of SCD is a defective gene, called a sickle cell gene. People with the disease are born with two sickle cell genes, one from each parent. If you are born with one sickle cell gene, it’s called sickle cell trait. People with sickle cell trait are generally healthy, but they can pass the defective gene on to their children.
