1.It is particularly common among people whose ancestors come from sub-Saharan Africa; Spanish-speaking regions (South America, Cuba, Central America); Saudi Arabia; India; and Mediterranean countries such as Turkey, Greece, and Italy. In the Unites States, it affects around 72,000 people, most of whose ancestors come from Africa. The disease occurs in about 1 in every 500 African-American births and 1 in every 1000 to 1400 Hispanic-American births. About 2 million Americans, or 1 in 12 African Americans, carry the sickle cell trait.
The below text is partially incorrect:
According to pubmed (a government run medical website) only 2 white people have been diagnosed with sickle cell. It was caused by a random mutation in their genes. For a white person to get sickle cell they must have a 1 in a trillion genetic mutation because there is no genetic history of sickle cell in white people. No genetic history of sickle cell means that it can not be inherited, it can only come from a mutation. Black people have much higher odds of having sickle cell because there is a genetic history of sickle cell in Africans. This means that it can be inherited from the parents. Sickle cell originated in three independent blood lines in Africa and one blood line in India 70,000-150,000 years ago. If you have sickle cell it means you are a descendent of one of these blood lines.
2. i am white and having sickle cell trait and alot off people around me having sickle cell disease
Yes, people who are "White" can carry sickle cell trait. Sickle cell diseases are actually a broad group of hemoglobinopathies (genetic blood disorders) that affect over 250 million people around the world, including people in Africa, North & South America, the Mediterranean and Middle East, South Asia, and Europe. Sickle cell trait is not a disease or illness - it is merely a descriptive term that indicates a person has inherited on "normal" hemoglobin gene (Hb A) and another "abnormal" hemoglobin gene (Hb S). Some individuals with sickle cell trait are at increased risk for sudden death if they are dehydrated or exposed to high altitudes, but this occurs rarely. If two individuals who have sickle cell trait (Hb AS) mate, then there is a 25% chance with each birth that they will have a child with sickle cell anemia (Hb SS); a 25% chance that they will have a child with normal hemoglobin (Hb AA); and a 50% chance that they will have a child with sickle cell trait. Sickle cell trait occurs in approximately 1 in 12 African Americans; 1 in 1400 Hispanics, and nearly 1 in 100,000 Whites.
a very VERY small percent of white people get sickle cell disease. first is black then hispanic and the bottom of the chart is Asian and white.
It it primarily the African-American people, those in the deep South states, who contract sickle cell anemia.
Yes, though it is rare.
Yes
yes
no
No
No
Sickle cell anemia is a inherited blood disorder. This means everyone who has sickle cell has inherited it from their parents. With this in mind it means there was a key ancestor in Africa or the Mediterranean who had the first sickle cell anemia and passed it on to their descendants.
You get Sickle-Cell Anemia by Birth,it is a genetic disorder.
An example of point-mutation is sickle-cell anemia. Sickle-cell disease is hereditary.
Sickle cell anemia is an autosomal recessive disease. Carriers have sickle cell trait, which confers resistance to malaria.
Yes, Sickle Cell Anemia is in fact a genetic disorder.
An example of point-mutation is sickle-cell anemia. Sickle-cell disease is hereditary.
sickle cell anemia
Sickle cell anemia -yes it is hereditary
Sickle cell anemia was discovered in the 1870's and carried many names, but 1922 it was officially named sickle cell anemia.
It sounds like you are looking for Sickle Cell Anemia.
It is more common for people of African descent to get sickle cell anemia. Sickle cell anemia is linked to survivors of falciparum malaria (P. falciparum), it is believed that the hemoglobin cells take on the sickle shape to give the mammal an increased survival rate.
