Yes, but the mutation happened many many thousands of years ago. It has been passed on through all these generations because the same gene that causes sickle cell anemia in a person that inherits two copies of the gene also causes resistance to the malaria parasite in a person that inherits only one copy of the gene.
In areas of the world where malaria is a common disease, the resistance to it is a stronger selective advantage than sickle cell anemia is a selective disadvantage; so the gene becomes very common in those populations.
What else can I help you with?
Is sickle cell anemia a point mutation?
An example of point-mutation is sickle-cell anemia. Sickle-cell disease is hereditary.
Sickle-cell anemia is an example of a point-mutation?
An example of point-mutation is sickle-cell anemia. Sickle-cell disease is hereditary.
Is sickle cell disease recessive?
Yes, Sickle Cell-Anemia is a genetic condition that is passed down from one generation to the other.
What genetic disease may be caused by a change or mutation in the hemoglobin gene?
sickle-cell anemia.
Is sickle cell anemia an autoimmune disease?
Sickle Cell Anemia is Autosomal Recessive. It arises from a mutation on the beta-globin gene of chromosome 11. Because Sickle Cell Anemia is an example of incomplete dominance, a person has the disease if they have two mutated beta-globin genes but only has the trait (is a carrier) if they have only one mutated beta-globin gene.
What are other names for sickle cell anemia?
Hemoglobin SS disease (Hb SS)
When a mutation in the hemoglobin gene causes what disorder?
While technically there are more than one, the main one by far is sickle cell anemia.
Is sickle cells disease hereditary?
Sickle cell anemia -yes it is hereditary
Can you get sickle cell from your parents?
Yes, and this is the only way to get sickle cell disease or sickle cell anemia. Sickle cell (both the milder "disease" form and the more severe "anemia" form) are caused by an inherited mutation in a protein that helps form the red blood cells - the defect results in red blood cells that are shaped like crescents or sickles, which is how the disease gets its name.
Is sickle cell anemia genetic or environmental?
Sickle cell anemia is genetic. It is an autosomal recessive disease.
Is sickle cell anemia a communicable or noncommunicable?
I don't know what a communitive disease is, and neither does the dictionary, but sickle cell anemia is an inherited abnormality. I hope that helps.If you are asking if sickle cell is a disease in which you can catch from other people. The answer is No. It is an inherited Blood disorder.
What disorder does a mutation in hemoglobin cause?
Sickle cell anemia.
