Sickle cell anemia is found in approximately 1 in 5000 people. It is mostly found in people from Sub-Saharan Africa do to the nature of the disease providing resistance to malaria.

What are the dangerous mutations that occur in sickle cell anemia?
Red blood cell changed due to sickle cell
Why sickle cell anemia resistance malaria?
Sickle cell anemia comes as the result of having two sickle cell chromosomes. One sickle cell chromosome makes people resistant to malaria. Unfortunately when people have two sickle cell chromosomes they can get sickle cell anemia. That makes it difficult for their blood to carry oxygen and under certain conditions makes their blood clump. The disease can be deadly. Drugs can help. It probably makes that person resistant to malaria. The sickle cell trait evolved in various places around the world where malaria is common such as Africa and Greece.
How old do you have to be to get sickle cell anemia?
You can live longer when you will follow up the proper medication
Why has sickle cell anemia been maintained in the human population?
Sickle-Cell AnaemiaSickle cell anemia is a disease that is controlled by alleles S and s .three possible combinations are SS , Ss ans ss . The most important reason why this allele is present in whole world including America is heterozygous superiority which keeps this gene in population Several major Universities whose main function is Technology, along with the Medical Schools associated with teaching in the Children's Hospitals have begun joining forces using nanotechnology to alter the genetics of the sickle cell trait. Among them is a collaborative effort between GA Institute of Technology, Emory University Medical School, and Children's Health Care Systems of Atlanta. Once this is accomplished, plans are already in the works to move on to another deadly disease initiated with inherited genes: Cystic Fibrosis. This is an excellent collaborative use of each genre's best abilities: cooperation vs competition.I earlier times this may have been negatively associated with eugenics, however that connotation is now being transformed with the positive aspects of actually changing genetics at the microcellular level to rid populations of certain killer traits, rather than attempts at 'perfecting the human race,' as in the despicable times of Hitler. This is not a genocidal experiment, but one aimed at saving lives of painful and deathly diseases, remembering sickle cell trait is mostly among Blacks.To get a clearer picture of why the allele is still present, just remember what the Hardy-Weinberg principle predicts:both allele and genotype frequencies in a population remain constant; that is, they are in equilibrium from generation to generation unless specific disturbing influences are introduced. Those disturbing influences include non random mating, mutations, selection, limited population size, "overlapping generations," random genetic drift, gene flow and meiotic drive.Since the homozygous recessive (when the Anaemia is actually expressed) and heterozygous condition do not affect mating probabilities, the allele will naturally remain within the population.
Do humans have different types of cells all the same shape?
Yes they are. There are many dirrerent shapes such as rod, bacilli, and many others.
What are the dangerous mutations that occur in sickle cell anemia?
Red blood cell changed due to sickle cell
A substitution of Val for Glu in the 6th amino acid causes what to occur?
sickle cell anemia
How frequent does sickle cell occur in the us?
Sickle-Cell Anemia is fairly rare but serious; if you think you have thse symptoms, contact a doctor asap.
Is sickle cell anemia substitution random or does it occur under the direction of molecules that direct protein synthesis?
no.people have to get sickle cell from there mother or father and if you have a friend that have sickle cell you can`t catch thank you for leting me tell you your answer!! bye

When does vitamin B12 anemia occur?
Vitamin B12 deficiency anemia is another type of megaloblastic anemia that develops when the body doesn't absorb enough of this nutrient.

What are types of anemia that reduce hemoglobin level?
The type of anemia that can reduce the hemaglobin level are the microcytic-hypochromic anemia and the normocytic-normochromic anemia. Microcytic-hypochromic anemia produces small, abnormally small erythrocytes and reduced hemoglobin concentrations. However, hypochromia can occur even in cells of normal size. This type of anemia results from a variety of conditions that are caused by disorders of iron metabolism, porphyrin and heme synthesis, or globin synthesis. Normocytic-normochromic anemia produces a destruction or depletion of normal or mature erythrocytes. Although the erythrocytes are relatively normal in size and in hemoglobin content, they are insufficient in number. This type does not share any common cause, pathologic mechanism, or morphologic characteristics and is less common than the others. The five distinct anemic conditions exemplify the diversity of this classification which are the aplastic anemia, posthemorrhafic anemia, haemolytic anemia, anemia of chronic disease and sickle cell anemia.
What anemia is most common in women?
iron deficiency anemia is most common in women occur because of menstrual blood loss
Explain why vascular occlusions are common in patient with sickle cell anemia?
RBCs contain HbS and with oxygen are flexible discs. When O2 is low, RBCs sickle or become elongated and rigid. As that blood circulates the body may have decreased oxygen levels. The RBCs (or erythrocytes) are unable to pass easily through small arteries so the cell membrane is damaged and tissue damage and multiple infarctions occur.
Can clozapine cause hemolytic anemia?
Hemolytic anemia indicates the early destruction of red blood cells. This can occur as inherited or acquired hemolytic anemia. Certain medicines can cause acquired hemolytic anemia, please check with the doctor.
