Sickle Cell Disease Introduction

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.

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.

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

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.

Sickle cell disease usually reveals itself early in a child’s life. Sickle cell disease brands a set of genetic red blood cell disorders. People with SCD have irregular hemoglobin called sickle hemoglobin, inside of their red blood cells. Hemoglobin is a protein located in red blood cells that transfers oxygen through the body. SCD is inherited which means that genes pass the disease from parents to their offspring. SCD is not infectious. A person cannot catch SCD, like a cold or STD. Alzheimer’s disease also runs in my family. My Great-Grand Mother is currently showing signs of dementia. Alzheimer’s is a disease that destroys remembrance and other key psychological functions used to preform everyday routines. Alzheimer’s is non-preventable and

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

Resulting in lack of blood flow to the region most commonly in the peripherals and organs causing pain in hands, feet, joints, fever and in severe forms develops in bones (Smeltzer, Bare, Hinkle, & Cheever, 2010). Sickle cell anemia is the most severe form of SCD, lesser forms include sickle cell hemoglobin C disease, sickle cell hemoglobin D disease, and sickle cell beta-thalassemia. (Smeltzer, Bare, Hinkle, & Cheever, 2010). . The term sickle cell trait is referred to people who are carriers of certain strand of abnormal gene, and it is a type of benign state of sickle cell hemoglobin C (Smeltzer, Bare, Hinkle, & Cheever, 2010). Though, if two people with the same traits may have child, the child will have a 1 in 4th chance of receiving two abnormal genes will develop sickle cell anemia (Smeltzer, Bare, Hinkle, & Cheever, 2010).

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.

According to Centers for Disease Control and Prevention “Sickle cell Trait is people who inherit one sickle cell gene and one normal gene have sickle cell trait (SCT). People with SCT usually do not have any of the symptoms of sickle cell disease (SCD), but they can pass the trait on to their children.” (sickle cell trait)

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.

When you pass an electric charge through a solution of hemoglobin, distinct hemoglobins move different distances, depending on their composition. This technique differentiates between normal hemoglobin (A), Sickle hemoglobin (S), and other different kinds of hemoglobin (such as C, D, E,). Medical Problems Sickle cells are destroyed rapidly in the body of people with the disease causing anemia, jaundice and the formation of gallstones. The sickle cells also block the flow of blood through vessels resulting in lung tissue damage (acute chest syndrome), pain episodes (arms, legs, chest and abdomen), stroke and priapism (painful prolonged erection). It

Sickle-cell disease majorly affects the hemoglobin that is present in our blood. The job of hemoglobin is to help transport oxygen and carbon dioxide to and from the cells throughout our body. Hemoglobin is present specifically in our red blood cells. Each red blood cell contains two hundred and eighty million hemoglobin molecules. Red blood cells normal shape is a biconcave shape because of the lack of many organelles and a nucleus. The shape is so important to a red blood cells functioning that if it is not shaped normally it has major consequences. The shape helps them to fit through capillaries easier and also allows for an increased surface area which results in easier gas exchange. Sickle-cell disease is a genetic disease that causes issues in the oxygen/carbon dioxide carrying hemoglobin molecules that are present in our red blood cells.

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.
