Sickle Cell Disorder
Sickle Cell is an inherited form of an abnormal red blood cell disorder. Sickle cell anemia is when your body produces abnormal hemoglobin (hemoglobin S) which is found in red blood cells. The abnormally shaped red blood cells are shaped in a crescent like form, this makes them sticky and rigid and prone to getting trapped in small vessels, which blocks blood flow to important parts of the body, this is how Sickle cell got its name. Sickle cell anemia occurs when a person inherits two abnormal copies of the hemoglobin gene, which is found in chromosome 11 in both parents. Hemoglobin or Haemoglobin is the iron-containing oxygen-transport metalloprotein in the red blood cell of all vertebrates as well as the tissues of some invertebrates. There are seven different types of sickle cell.
Symptoms of Sickle Cell are severe

Sickle Cell Anemia, is the most common disease in which it occurs in children who get the disease from both parents who have the gene, sickle cell anemia is when your body produces abnormal hemoglobin (hemoglobin S) which is found in red blood cells this form of sickle cell is common of those with African and Indian descent.Sickle Hemoglobin-C(SC), most commonly found in those of West African, Mediterranean and Middle Eastern descent; individuals with Sickle Hemoglobin-C disease(SC) have both hemoglobin C and hemoglobin S which have similar symptoms as Sickle Cell Anemia but less anemia due to a higher blood count.Sickle Beta-Plus Thalassemia, found in those of Mediterranean and Caribbean descent. Sickle Beta-Plus Thalassemia contain substitutions in both beta global genes. When no beta global is produced symptoms are almost identical to Sickle Cell Anemia, with severe cases individuals needing chronic blood transfusions. Sickle Hemoglobin-D Disease commonly found in those with Asian and Latin American
When Malaria is present and infects red blood cells, parasites can infect cells carrying defective hemoglobin which may result in death. Allele frequency changes over time depending on the pressures or circumstances facing a particular population. African populations are especially impacted by both malaria and sickle cell anemia. Depending on the impacted population, allele frequency often shifts and well suited organisms are likely to survive and allele frequencies can increase. When a population is effected by disease or other circumstances, allele frequency may decrease or change. HbA (normal hemoglobin) and HbS (defective hemoglobin) have varying frequencies and while the HbS gene is present in populations it is
Discussions in regards to race can be fraught with extreme opinions, to examine this subject in a more dispassionate light it is helpful to first define the terms. Race is distinctly different from ethnicity or culture, but is often combined in both writing and thought. From a biological perspective, the description of race in human populations is meaningless, but examined from a cultural basis it can make an enormous difference to a population’s wellbeing, or survival, based solely on their difference in morphology.
In this article, sickle cell anemia is defined as a hereditary disease that destroys red blood cells by causing them take on an elongated and rigid "sickle" shape. In addition, a different type of hemoglobin called Hemoglobin S, is the protein in red blood cells that carry oxygen throughout the body. This protein starts to wrap around other red blood cells when oxygen is lacking to form a helical shape. Once this happens the cells cluster together and elongate and the cells start to "sickle". A person who has sickle cell anemia can only get it if both of their parents carry the sickle cell trait, if only one parent has the trait then there children are at risk for having the trait.
Sickle cell anemia is an anemia that is inherited and mostly affects people whose heritage can be traced back to places where malaria was prevalent. There are approximately 100,000 Americans that have the disease and many more with the trait. Several of my family members are afflicted by this medical condition that causes red blood cells to take on an irregular shape.
Sickle Cell anemia is a group of inherited red blood cell disorders, or a collection of recessive genetic disorders characterized by a hemoglobin variant called Hb S. Normal red blood cells are round like doughnuts, and they move through small blood tubes in the body to deliver oxygen. Sickle red blood cells become hard, sticky and shaped like sickles used to cut wheat. When these hard and pointed red cells go through the small blood tube, they clog the flow and break apart. This can cause pain, damage and a low blood count, or anemia. There is a substance in the red cell called hemoglobin that carries oxygen inside the cell. One little change in this substance causes the hemoglobin to form long hard rods in the red cell when it gives
Sickle cell anemia occurs when a person inherits two abnormal genes (one from each parent) that cause their red blood cells to change shape. Instead of being flexible and round, these cells are more rigid and curved in the shape of the farm tool known as a sickle - that's where the disease gets its name. The shape
Sickle Cell Disease is an autosomal recessive genetic disease that occurs due to a mutation in the β-globin gene of hemoglobin. Autosomal meaning that it is not linked to a sex chromosome, so either parent can pass on the gene to their child. This mutation is a result of a single substitution of amino acids, Glutamic for Valine at position 6 of a β globin chain. The presence of this mutation causes
Health care disparity with sickle cell Disease Patient’s Thesis Statement. Barriers to racial health care equity include the health care system (insurance, funding), the patient (poor health literacy, fear, mistrust), the community (awareness, advocacy), and the providers (bias, attitudes, expectations, stereotyping). Sickle cell disease (SCD) is the most prevalent genetic hematological disorder worldwide predominantly affecting populations of West African and African Caribbean descent, as well as populations of Asian, Middle Eastern, and Mediterranean origins (Burne, 2008). It affects about 80,000 people in the United States and is the most common inherited blood disorder (O’Cconnor, 2014). It affects 1 in every 500 births of African
Sickle Cell Anemia is a disease that affects how oxygen is carried throughout the body by blood. Specifically, sickle cell anemia is characterized by a change in the shape of red blood cells from a smooth donut shape to a crescent or sickled shape. The sickled cells are very long and stiff, so many times
Sickle Cell Anemia is a very serious disorder and people suffer from it every day. It is a genetic disorder that causes the hemoglobin in the red blood cell to distort and form into a sickle like shape. The name comes from the shape of the blood cell after it is mutated. A person who has sickle cell anemia got it from inheriting from the parents. It is the most common inherited disorder in the United States. It is also has four other names this disorder can go by HbS, Hemoglobin S Disease, SCD, and Sickle Cell .(https://ghr.nlm.nih.gov)the blood cell is formed wrong turning it into a sickle or crescent shape. Sickle cell is only a disorder. It can also be treated a lot of different ways.
Thousands of years ago, a genetic mutation occurred in people from the Mediterranean basin, India, Africa, and the Middle East. As the Malaria Epidemic attacked people of these countries, carriers of the defective hemoglobin gene survived. Carrying one defective gene means that a person has a sickle cell trait. Two parents with the trait will produce a child with sickle cell anemia. People of these countries migrated and spread to other areas. In the Western Hemisphere, where malaria is not much of a problem, having the abnormal hemoglobin gene has lost its advantage. Any child born from parents that each has the trait will be born with the disease.
Sickle Cell Disease is an illness that affects people all across the globe. This paper will give a description of the sickness through the discussion of the causes, symptoms, and possible cures. Sickle Cell Disease (SCD) is a "group of inherited red blood cell disorders."(1) These disorders can have various afflictions, such as pain, damage and a low blood count--Sickle Cell Anemia.
The sickle cell disease is an inherited blood disorder that affects red blood cells. People with sickle cell have red blood cells that have mostly hemoglobin's, Sometimes these red blood cells become sickle-shaped or crescent shaped and have trouble going through small blood vessels. When sickle-shaped cells block small blood vessels, less blood can get to that part of the body. Tissue that does not get a normal blood flow eventually becomes damaged. This is what causes the problems of sickle cell disease.
According to Conran,N. (2015) ; The term sickle cell disease (SCD) describes a group of inherited Red Blood Cells (RBCs) disorders. People with Sickle cell anemia have abnormal hemoglobin, called hemoglobin S or sickle hemoglobin, in their RBCs.
Sickle Cell Anemia is a group of disorders that cause red blood cells to become misshapen and break down. Sickle cell disease is the most common inherited blood disorder in the United States, affecting 70,000 to 80,000 Americans (Ashley-Koch, Yang and Olney). Sickle Cell Anemia causes your red blood cells to be thin, stiff, and shaped like a sickle. But your red blood cells are supposed to be round and soft. A person that is diagnosed with sickle cell anemia, their blood cells start to become clogged, causing blood clots, which can cause a great amount of health issues including: infections, stroke, and acute chest syndrome. People get sickle cell anemia by inheriting a mutated gene from both of their parents. On the down side, there is not currently an effective cure for sickle cell anemia, there are several different therapeutic approaches to treating and attempting to cure the disease and help people who are affected with sickle cell anemia better manage their symptoms. There have also been several great scientists that dedicated a lot of research to help find a cure for sickle cell anemia.
