Which race has sickle cell anemia?
Sickle cell disease is more common in certain ethnic groups, including: 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.
Can only Black people get sickle cell?
Answer. 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 white matter disease?
White matter disease is the wearing away of tissue in the largest and deepest part of your brain that has a number of causes, including aging. This tissue contains millions of nerve fibers, or axons, that connect other parts of the brain and spinal cord and signal your nerves to talk to one another.
What percentage of Caucasian have sickle cell?
3.2. The majority of children with SCA and sickle cell trait were black (86.3% and 80.2%, respectively). Among SCA births, 2.5% were white, 1.2% were multiracial, and 8.3% were of unknown race. Among sickle cell trait births, 7.0% were white, 5.3% were multiracial, and 5.9% had unknown race.
Why is sickle cell more common in Africa?
The disease is most common in sub-Saharan Africa, where as many as 45% of people are carriers. It has become so widespread there because being a carrier offers a survival advantage against malaria. The Middle East doesn’t really have a malaria problem, and the overall sickle-cell carrier rate is low.
Is sickle cell curable?
Stem cell or bone marrow transplants are the only cure for sickle cell disease, but they’re not done very often because of the significant risks involved. Stem cells are special cells produced by bone marrow, a spongy tissue found in the centre of some bones. They can turn into different types of blood cells.
Why is sickle cell most common in Africa?
Where did sickle cell originate from?
SCD originated in West Africa, where it has the highest prevalence. It is also present to a lesser extent in India and the Mediterranean region. DNA polymorphism of the beta S gene suggests that it arose from five separate mutations: four in Africa and one in India and the Middle East.
Can females with Down syndrome reproduce?
Yes. A woman with Down’s syndrome can have children. If her partner does not have Down’s syndrome, the theoretical chance of the child having Down’s syndrome is 50%. There have been only a few reports of men with Down’s syndrome fathering children.
