Essay on Sickle Cell Lab

believed that genetically aberrant hemoglobin evolved as a protection against malaria."(2) It has also been said that, "People with a single copy of a particular genetic mutation [sickle cell trait] have a survival advantage. One copy of the mutation confers a benefit." (3) Its quite interesting to find that original purpose of this gene was

People with sickle cell anemia have inherited two sickle cell genes, one from each parent. A child who has inherited the sickle cell gene from only one parent will not develop the disease, but will have sickle cell trait. People who have sickle cell trait don't have sickle cell anemia or symptoms of the disease, but they can pass the sickle cell gene to their own children.

Sickle cell crisis is an acute form of sickle cell disease where pain and sickling are extensive (Byar, 2013). SCD is a genetic disease that predominantly affects black people of African decent (Gersten, 2016). Abnormal hemoglobin chains are the main issue with SCD (Byar, 2013). Normal hemoglobin chains are comprised of 99% hemoglobin A (HbA) however, in SCD an abnormal form of the gene, hemoglobin S (HbS) is present in approximately 40% of total hemoglobin (Byar, 2013). In order for a person to be born with SCD, both parents must carry the abnormal gene, HbS (Byar, 2013). HbS is extremely sensitive to the changes in oxygen amount of the RBC and when exposed to decreased oxygen the HbS cause the RBC to distort and become sickle-shaped,

This mutation paper is to give information on the Sickle Cell disease. This is a negative disease to have because the Sickle Cell Disease decreases the health of the person that has the disease and limits what they can and cannot do. Sickle Cell Disease is a red blood cell disease that causes ab normal hemoglobin to from in the veins. Hemoglobin is the protein that carries oxygen throughout the body to help with the respiratory system. The cause of the genetic mutation is inheritance or getting the disease from the parents the disease is found on chromosome 13 while the hemoglobin is still in beta phase on gene HB A. The disease typically shows symptoms within the first 5 to 6 months of birth and being diagnosed with Sickle Cell Disease. The symptoms include painful swelling on the hands and feet, and Jaundice, which causes a white color to form under the eyes, and turns the skin color yellow.

It has always been assumed that genetics and lifestyle play a major role in the presence of health disparities and health care issue that affects African-Americans. This paper provides a historical background to a key disease more prevalent in the African American community, Sickle Cell Anemia, the history behind the disease, genetic mechanisms that influences once probability of inheritance and in-depth treatment on how to manage, prevent and sustain a healthy lifestyle when dealing with sickle cell anemia. Sickle cell anemia is a hereditary disease that alters important aspects of the body physiologically and can be inherited via genes. Sickle cell disease (SCD) was first identified in 1910 and has existed in the continent of Africa for five

Hypothesis: African-American parents with the Sickle Cell Trait have the greatest risk of passing Sickle Cell Anemia to their offspring.

Sickle cell disease (SCD) occurs in 1 out of every 365 African American births compared to 1 out of 16,000 Hispanic-American births (1). SCD is a group of red blood cell disorders in which patients have a sickle or moon-shaped red blood cell due to an abnormal S hemoglobin. While sickle cell disease is relatively rare in American births, this is an alarming statistic among people of Sub-Saharan (west and central) African descent. An interesting fact is that SCD occurs more often among people from parts of the world where malaria is or was common, such as Sub-Saharan Africa (1). In addition, it is believed that people who carry the sickle cell trait are less likely to have

The method of transmission of this disease is inherited by both parent who have (SCD) so when they produce a child the child will have 2 sickle cell genes.

Sickle cell anemia affects a wide range of demographics, from young to old. However, there are specific groups of people who are likely more prone to this disease than any other group. This disease affects millions of people worldwide regardless of age, but it is particularly common amongst those who derive from specific regions of the world. Sickle cell anemia is most common in those whose ancestors are derived from the sub-Saharan region of Africa. Furthermore, other regions that are known to have a high number of people containing sickle cell anemia are from Mediterranean countries, the Arabian Peninsula, and Spanish-speaking regions as well ("Who Is at Risk for Sickle Cell Anemia?"). This disease originated from the sub-Saharan region of Africa, and later migrated to other areas through the spreading of other diseases such as malaria. This is due to the fact that sickle cell disease occurs habitually in areas that are prone to diseases such as malaria. Although this disease can affect anyone, the highest cases of sickle cell anemia were found in African-Americans than in any other race. In the United States, sickle cell disease affects about 70,000 to 100,000 Americans ("Who Is at Risk for Sickle Cell Anemia?"). The statistics show that 1 out of every 500 births is affected by sickle cell disease for African-Americans. For the Hispanics, 1 out of every 36,000 births is prone to sickle cell disease ("Who Is at Risk for Sickle Cell Anemia?"). The age ranges for which a

The probability of inheriting a disease is not random. There are several factors that determine the chances on inheriting a disease such as race, gender, genetics, etc. A person of Caucasian decent is more likely to develop cystic fibrosis, an Asian person has a higher chance of inheriting Kawasaki disease and there is a very high rate of Sickle Cell Anemia among people of African lineage. Sickle Cell disease is inherited and it affects the anatomy of the red blood cells, resulting in a sickle shape which then affects the functions of red blood cells causing a blood disorder. Sickle Cell is a recessive disease and persons affected have both copies of the hemoglobin S gene. This genetic defect causes red blood cells to become sickle-shaped (cresent shape). The abnormal shape severely impede the ability of red blood cells to pass through small blood vessels. This impediment caused by the sickle-shaped red blood cells decreases the flow of blood to parts of the body. This reduced blood flow to tissues causes hypoxia and subsequently leads to tissue damage. This alteration in the function of red blood cells is what leads to the complications of sickle cell disease. There are various types of sickle cell disease. The most common types of sickle cell disease are Sickle Cell Anemia (SS), Sickle-Hemoglobin C Disease (SC), Sickle Beta-Plus Thalassemia and Sickle Beta-Zero Thalassemia. Often conflated with sickle cell disease is "Sickle Cell Trait". Sickle cell trait means that a

(NHLBI, 2015) There are a few scenarios of the passing of the disease or trait from the parent to the offspring. If one parent has the gene it can be passed to the child, causing the child to be a carrier of the trait. In other words, the child will be able to produce normal hemoglobin as well as the sickle shaped hemoglobin. They will also be able to pass it to their offspring. If both parents carry the trait the child has a 50 percent chance of being a carrier, percent chance of not getting the gene at all, and 25 percent chance of having sickle cell anemia.

I have done my research on sickle cell disease throughout the paper; I will distinguish the difference between sickle cell disease and sickle trait, the stages of sickle cell disease during childhood,

Every citizen of Population A was vaccinated when the experiment began, and every new baby was vaccinated immediately after birth. Allele frequencies were calculated every 20 years. After 100 years, 360 out of 1,000 people in Population A are homozygous recessive for sickle cell anemia (ss genotype).

Sickle cell anemia mainly affects people with African, Mediterranean, Middle Eastern, and Indian ancestry. A person with sickle cell anemia inherits two sickle cell genes, one from each parent. It cause the red blood cells to change and become crescent shaped. Normal red blood cells are disk shaped and move easy through the blood vessels. The primary problem is hemoglobin, it is a protein molecule in red blood cells that carries oxygen from the lungs to the body’s tissues and returns carbon dioxide from the tissues to the lungs. In sickle cell anemia, the hemoglobin is flawed. The cells become sickle shaped and can’t move as easily through blood vessels. Sickle cell anemia has one main cause, in order for sickle cell anemia to happen, a sickle

The individuals that had AS, which is heterozygous for hemoglobin and sickle-cell anemia, maintained a higher survival rate in the wet areas of Kenya. The population that was heterozygous for hemoglobin and sickle-cell anemia would not contract malaria, or they would contract malaria, but be capable of living from the disease. The individuals that are heterozygous for sickle-cell anemia and hemoglobin are an excellent example of natural selection affecting the genotype of a population in a specific area; the people in Kenya acquired a drastic increase in percentage of those with the gene that is heterozygous for sickle-cell anemia and hemoglobin.
