Hypothesis: African-American parents with the Sickle Cell Trait have the greatest risk of passing Sickle Cell Anemia to their offspring. 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. In conclusion, sickle cell anemia and the sickle cell trait are more common in African-Americans and people who live in places where malaria is common. Individuals with the trait seem to live normal and healthy lives, however individuals who have the trait and experience high altitudes or vigorous exercise tend to feel unwell because of the lack of oxygen getting into the cells causing them to sickle. In addition, the sickling of the cells can be reversible to a certain extent in people with the trait, however people who have sickle cell anemia the sickling of the cells is irreversible due to the severity of the disease. In this study,
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
The sickle cell disease affects about 100,000 people in the America. The most common ethnic group the sickle cell anemia is seen in is African Americans and Hispanics. Approximately one in every ten African American and one in every one hundred Hispanic Americans have the sickle cell trait. Approximately two million people have the sickle cell trait in America. Approximately one in five- hundred African Americans and one in one thousand to one thousand and four hundred Hispanic-Americans have sickle cell disease. No universal cure has been found for sickle cell anemia (“Facts About Sickle Cell Trait And Disease,”n.d.). Sickle cell anemia affects many Americans and a universal cure needs to be found.
Approximately 100,000 people suffer from Sickle Cell Anemia everyday and about 2 million people have the Sickle Cell trait in the United States alone. Sickle cell disease is the most common inherited blood disorder in the United States, affecting 70,000 to 80,000 Americans (Pruthi 2018). The disease is estimated to occur in 1 in 500 African Americans and 1 in 1,000 to 1,400 Hispanic Americans (Pruthi 2018). Sickle cell anemia is an inherited form of anemia, a condition in which there aren't enough healthy red blood cells to carry adequate oxygen throughout your body normally, your red blood cells are flexible and round, moving easily through your blood vessels. In sickle cell anemia, the red blood cells become
Sickle cell anemia is a blood disorder that happen very commonly in the African descent.
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
Sickle Cell Anemia is a fatal hereditary illness, in which there is insufficient amount of red blood cells to to carry the right amount of oxygen throughout the body. In the United States people with Sickle Cell Anemia is that of an African Descent or would classify themselves as black.
Sickle Cell Anemia is when a red blood cell is shaped into a different form and causes real bad diseases and sickness. Sickle cell Anemia also can be caused from blood loss. The sickle cells can get stuck in your blood cells and you won't be able to move your blood vessels. The molecule in the red blood delivers oxygen throughout the body. Other names for Sickle Cells is HbS, Hemoglobin S, Hemoglobin SS. Three important facts you need to know about sickle cell anemia is disorders, diagnosed, and genetic disorders.
Sickle Cell Disease is a genetic disease. If you have the disease, you have a lower life expectancy while you are also given a tremendous amount of pain to endure. The disease is inherited and it also causes a mutated hemoglobin. When you have this disease, instead of your red blood cells being circular like a moon it is much smaller like the shape of a crescent moon. Our red blood cells
But what does this mean, well first a mutation is an abnormality much in the way that cancer is an abnormal growth within the body. These are mutations, unfortunately we don’t get the same types of mutations that the X-Men have. Our body’s are made so that everything perfectly fits in each hole or socket, well red blood cells are normally round and smooth. Red blood cells are designed to be able to flow smoothly through blood vessels which is why they are smooth and round. Like mentioned earlier Sickle cell anemia is a mutation of the hemoglobin or the blood cells themselves. The blood cells stack on one another into long tube like structures. The cells become sickle shaped and become rigid. The sickling starts on the chromosome 11. While the cells are stacking up they are damaging vital organs such as the lungs and the heart. Everyone gets a copy of the hemoglobin gene from each parent. If both genes are carriers of the sickled trait, there will be high probability that the offspring will have Sickle cell anemia. Sickle cell is not contagious and cannot be caught, it is passed along genetically. Through research we have found that there are different types of the sickling disease. There is Hemoglobin SS (Sickle cell anemia), hemoglobin SC and hemoglobin sickle betathalassemia which is known as Mediterranean
Sickle cell anemia is a disease that is found in about seventy thousand to one-hundred thousand people in a year here in the United States, most commonly found in African-Americans. This disease occurs in the blood where the hemoglobin attaches itself to the oxygen in the lungs and then carried all throughout the body. When this occurs the red blood cell is changed to rigid and the shape turns to a “C” (A.K.A. Sickle) which is where the disease got its name. The C like cell may get stuck and block blood flow to vital organs which can cause a stroke, acute chest syndrome, organ damage, and other disabilities. Sickle cell is unfortunately an inherited disease which is either passed down by both parents or if one parents has the trait and the
What is Sickle Cell Anemia? Sickle Cell disease is a blood disorder that is inherited. By inherited I mean passed down from parents to their children. Babies are usually born with sickle cell disease. When they inherit two abnormal genes, one from each parent. Abnormal genes cause the body’s red blood cells to change shape. This being the effect of having sickle cell disease.
Sickle Cell Disease is a genetic disease caused by a SNP (Single Nucleotide Polymorphism). Which means it is caused by a single letter gene mutation. Through the advent of CRISPR/Cas9 the disease might be cured. It is a serious reality and will enter medical trials within a handful of years. Sickle Cell Disease is an inherited disease that predominantly affects people of African descent. Red Blood cells become rigid and sickle shaped, causing blockages and pain crises. In cases of Sickle Cell Disease the Beta-Globin are mutated causing faulty and deformed Hemoglobin proteins thus creating sickled and short-lived Red Blood Cells.
Sickle cell trait is the heterozygous state of the sickle cell gene, also called sickle hemoglobin (HbS) (DynaMed, 2015). The sickle hemoglobin (HbS) is an abnormal hemoglobin resulted from an atypical mutation of a normal hemoglobin. Heterozygous individuals are carriers of the sickle cell trait, and they are usually asymptomatic (DynaMed, 2015). There are no interventions or referral indicated for infants. The risk factors for sickle cell gene include ancestry from Africa, Caribbean, Central and South America, India, Mediterranean, and the Middle East (DynaMed, 2015). Although Sickle cell trait is a benign condition, studies have found that under extreme conditions such as severe
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.
