Sickle Cell Anaemia

Sickle Cell Anemia is a genetic disease which can only be caused by both parents passing the sickle cell gene down to their offspring. About 2 million Americans carry the Sickle Cell gene but don’t have the disease. If two people with the gene marry, there’s a one in four chance that their children can end up having the disease. The gene is common with African, Spanish, Mediterranean, Middle Eastern, and Indian people. In the United States, Sickle Cell Anemia affects 1 in every 500 African American children born, and 1 in every 900 Hispanic children born.

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

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 (SCA) is an inherited blood disease which causes normal, round, healthy red blood cells to transform into sickle-shaped cells. Normal red blood cells are flexible and can easily pass through capillaries to bring oxygen to different parts of the body. However, sickle cells are fragile, and can easily die, leading to anemia (red blood cell deficiency). SCA can also cause blood vessel occlusion (blockage of blood vessels), tissue infarctions (death due to lack of oxygen), bone, joint, and abdominal pain, yellow eyes and skin, pale skin, delayed growth, increased risk of infections, and damage to organs. The disease is passed on by autosomal recessive inheritance, which means both parents of a child must have the defective gene for the child to be affected. If only one gene is inherited, the victim becomes a carrier of the sickle cell trait, producing only some sickle cells with little or no symptoms. This means two people with the trait have a 25% chance of having a baby with sickle cell disease, 25% chance of them having no defects, and 50% chance of the baby becoming a carrier as well. When the gene is inherited, it mutates the beta (β) globin gene in chromosome 11, changing the hemoglobins produced using instructions from the gene from a healthy hemoglobin A (Hb A) to a mutated hemoglobin S (Hb S). Many tests can be done to check for sickle cell disease, the most common being an ordinary blood test, where the blood is examined for hemoglobin S. If the

Sickle Cell Disease or also widely known as Sickle Cell Anemia is a genetic mutation caused in red blood cells destroys its own cells within and reshaping the cell wall resembling crescent or sickle shape; getting its name of the sickle cell disease. These sickled shaped cells attempt to perform its normal function of circulating oxygenated and deoxygenated RBC and gets lodged in small vessels causing vaso-occlusion. Where vaso-occlusive take effect, rest of the body is not receiving oxygen becoming oxygen deprived results in acute and chronic pain and organ damage (Valerie Mann-Jiles, 2015). This disease a lifelong condition affecting not just the person carrying the disease but the whole family. Treating this disease

Sickle Cell Disease, also referred to as SCD, is a genetically inherited disease that causes abnormal hemoglobin, called hemoglobin S or sickle hemoglobin, in red blood cells. This disease currently affects about 90,000-100,000 Americans, a majority being African-American. Because SCD is genetically inherited, it is not contagious. It is inherited when both parents of a child carry the sickle cell trait, also called SCT. SCT and SCD are not the same. In SCT, the person is generally healthy and does not endure what one with SCD does, they are simply a “carrier” of the sickle cell trait. SCD cannot be inherited if only one parent is a carrier. If both parents are carriers of the sickle cell trait, the child still only has a 25% chance of being born with sickle cell. They have a 50% chance of being born with a single trait, making them a carrier, and a 25% chance of being born with normal hemoglobin. About 1 in 13 African-American babies are born as a carrier and 1 in 365 are born with the disease.

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

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 anemia is a disorder that is caused by the abnormal shape of hemoglobin cells in the body. In lecture we learned that hemoglobin is the molecule that is present in red blood cells. Hemoglobin is responsible for supplying oxygen to other cells throughout the body. Red blood cells are normally rounded in shape, defected cells are in a long shafted shape, which gives the disease its name. When red blood cells sickle, they break down which causes anemia of the cells. Sickle cells can result in an individual having a low red blood cell count, having repeated infections, and suffering from long episodes of pain in different parts of the body. The disease can also cause delayed growth in children, shortness in breathe, fatigue, swollen feet and hands, and also vision problems.

The genetic disorder I will be discussing is Sickle Cell Disease. Sickle Cell Disease is an inherited blood disorder. Children who have this disease have two defective hemoglobin S genes, which they receive one from each parent. This gene occurs in chromosome 11. The sickle cell gene is passed from generation to generation in a pattern of inheritance called autosomal recessive inheritance. This means that both the mother and the father must pass on the defective form of the gene for a child to be affected. If only one parent passes the sickle cell gene to the child, that child will have the sickle cell trait.

This paper looks in depth at the disease process of sickle cell anemia. It starts out by covering the pathophysiology of the disease and how it functions within the body. The second section of the paper covers the ways to manage sickle cell anemia, whether it be by medication or blood transfusions, or both. The third section is meant to emphasize the important assessment details and how things should be prioritized for the patient with this disease; it also defines which lab values are most important to monitor for the patient. The paper concludes with a case study which details an African American family wishing to start a family. They undergo genetic counseling and receive information on the impact of sickle cell anemia in regards to

Sickle cell disease (SCD) is an autosomal recessive disease that is common in African Americans. This disease arises from a single base-pair substitution of thymine for adenine and this makes valine in its place of glutamine in the sixth position of the Beta-globin molecule. When this swap occurs in a homozygous state and this is the sickle cell disease. Clinical signs result from polymerization of the abnormal haemoglobin and the sickling of cells. (Thompson, 2010)

This disease is a genetic disease and it is hereditary. It is inherited as an autosomal recessive disease. This means that in order to get the gene you must receive a recessive trait from your mother and your father. The parents could both be heterozygous for the trait and therefore not have the disease, but instead they would both be a carrier. There are only a few ways that the parents could possibly pass the trait. One possibility of having a child with sickle-cell disease is if both parents are heterozygous and they both pass on their recessive allele, (25% chance for offspring to have sickle-cell disease). Another possibility
