Thalassemia is a blood disorder that has a deadly effect on the human body. It is an inherited blood disorder that affects the body's ability to make healthy haemoglobin, the iron-rich protein found in red blood cells. Haemoglobin is needed to carry oxygen to all parts of the body, and carbon dioxide to the lungs to be exhaled. The following essay will be discussing Thalassemia and the results of genetic testing. This disorder is passed on through genes and it is vital to understand how this disease can affect the future generations of families. It is caused by either a genetic mutation, or a deletion of certain key genes. T t
T TT Tt t Tt tt
The two types of Thalassemia are Thalassemia Major and Thalassemia Minor. Thalassemia Major shows symptoms and occurs when both the recessive genes carry the disorder, which results in symptoms. Thalassemia Minor occurs if you receive the bad gene from only one parent. People with this type are only carriers of the disease. Most of the time, they do not have symptoms. If both parents are carriers of the disease then their off spring has a 50% chance that they will carry the gene, a 25% chance that the child will not have the gene and a 25% chance that the child will suffer from the disease. Some of the symptoms for Thalassemia are: fussiness, paleness, frequent infections, poor appetite, failure to thrive, jaundice (yellowing of the skin and whites of the eyes) and enlarged organs.

Diagnostic tests can detect many genetic conditions caused by chromosome abnormalities. They usually can tell parents whether or not their fetus has a particular genetic problem. Genetic testing can happen by getting a sample of DNA. E.g., blood or hair. It shows the differences in the genes and chromosomes. It can help a people figure out if they have a disorder or if they are a carrier of one. The physical risks of the gene test itself…...

Effect of Sickle Cell Disease Gene

...trait and the other parent has normal hemoglobin the child may inherit. How do you know if you have sickle cell trait? You can easily get a blood test form most hospital, medical centers and doctor offices. When you get the blood test, it determines if you have sickle cell trait. As in women, they can find out if they have sickle cell traits during their pregnancy to find out if the child is going to have the trait or the disease. There are three main type of sickle cell disease. Hemoglobin SS disease, Hemoglobin SC disease, and Hemoglobin Sb (beta) thalassemia disease. People with Hemoglobin SS have two copies of the hemoglobin S gene. If you have the Hemoglobin SC disease you have one copy of the hemoglobin S gene and one copy of the hemoglobin C gene. The last one is Hemoglobin Sb (beta) thalassemia disease which is the affected patients have one copy of the hemoglobin S gene and one copy of a hemoglobin beta-thalassemia gene. So what are the chances of having a baby with sickle cell disease? Statistics showed that if one of the child’s parents has sickle cell trait and the other parent is normal then there is a 50% chance the child will have normal red blood cell or 50% chance having sickle cell traits. Sickle cell trait is a condition in which a person makes both Hgb S and Hgb A. There are many people that have sickle cell traits that seem to be perfectly find because there body produce a great amount of Hgb A cover up the bad Hgb S. With one parent having the......

Also the blood sample results show low Serum Iron, low MCV and MCHC which is also symptoms of IDA. The Chemistry of Cooley’s Anemia This case study is about a child named Peter; his parents are Max and Andrea Foresti a young couple that has only been married for two years. They are waiting to be seen the family physician, Dr. Mary Litton. They are worried about the number of infection Peter has been suffering from. They are worried it might be anemia but the doctor had order blood work at his last appointment and informed them she has a diagnosis of thalassemia. Thalassemia is a genetic blood disorder that causes hemoglobin, the protein in your body that binds and transports oxygen, to be malformed. The doctor proceeds to go over the complications of this and explains in detail what they will have to do, if they choose to do so. It will entail blood transfusions on an outpatient basis every two to four weeks that will last four to six hours and they will have to administer the deferoxamine each night by placing a needle under Peter’s skin. This will only prolong his life to a 90% chance of surviving to age 25. 1. What is the basic structure and function of hemoglobin?

Your blood his three deferent types of blood cells: Red blood cells, which carry oxygen in your blood tissues. White blood cells, which fight infections, and Plates, it helps to coagulate. Unfortunately, some people have an abnormal function of blood. That why is important for you to know about some common blood disorders? This paper will focus on the causes, symptoms, and treatments of Thalassemia and Myelomas. First blood disorders disease is Thalassemia. Thalassemia: is a genetic blood disease. If you have it in your family you may have it two. There is primary cause of thalassemia. The first cause is that body produce less healthy red blood cells and that can lead to less hemoglobin. Thalassemia is also caused by abnormal cell structures. People with thalassemia may show variety of symptoms. The most common symptoms are fatigue, shortens, of breath and paleness. There are two common ways to treat thalassemia. First treatment is that potion can have a blood transfusion or bone marrow transplant. The second treatment is that the potion can replace sick genes. Usually people who are born in Middle East or GREAL have this disease can have this disease Also there is another common disease called Myeloma.

This type of Anemia during pregnancy can cause birth defects. The lack of this vitamin can lead to this type of Anemia. Causes: • Alcohol abuse • Poor diets • Prolonged drug therapy • Bacteria Symptoms: • Nausea • Anorexia • Fainting • Irritability • Forgetfulness • Pallor • Inflammation of the tongue - Thalassemia: This is one of the generically inherited types of Anemia and it occurs when our body’s genes, which are responsible for proper hemoglobin production, become damaged or mutated. Causes: • The only way to get Thalassemia is to inherit one or more defective hemoglobin genes from our parents. Symptoms: • Facial bone deformities • Slow growth • Protruding abdomen • Dark urine • Pale appearance - Aplastic Anemia: This is one of the rarer types of Anemia which occurs when the body does not make sufficient red and white blood cells. Causes: • High-dose radiation and chemotherapy treatments • Exposure to toxic chemicals • Use of certain drugs • Autoimmune disorders • Bone marrow diseases Symptoms: • Blood in stool • Sinus tenderness • Enlarged liver or spleen • Dizziness • Oral thrush - Hereditary Spherocytic......

...outer symptoms. Weakness, fatigue, and pallor are very common symptom. Symptoms of severe anemia are shortness of breath, rapid heartbeat, lightheadedness, headache, ringing in the ears, irritability, restless leg syndrome, mental confusion, dizziness, fainting, and dimmed vision. Iron deficiency anemia- the most common type of anemia; occurs because of low iron levels. Folic acid deficiency anemia- levels of folic acid are low because of inadequate dietary intake or faulty absorption. Pernicious anemia- inability of the body to properly absorb vitamin B12 Hemolytic anemia- red blood cells are destroyed prematurely. Sickle cell anemia- inherited abnormality of hemoglobin; occurs mainly in people of African or Mediterranean decent. Thalassemia anemia- inherited disorder in the synthesis of hemoglobin. A plastic anemia- decreased bone marrow production. Determining the cause of anemia is very important because it may be the sign of a very serious illness. A physician should ask about family history of anemia, gallbladder disease, jaundice, and enlarged spleen. A stool test should be done and the physician should check for swollen lymph nodes, an enlarged spleen, and pallor. Laboratory tests can test both the numbers of red blood cells as well as look at their appearance. Because there are so many different types of anemia as well as causes, treatments vary widely. If the type of anemia results from a vitamin deficiency and there is no underlying cause, treatment is......

...but many most likely do not know how it exactly works. When looking at sickle cell blood cells you can tell the differences between normal blood cells and sickle cell blood cells. Sickle cell blood cells, are crescent shaped, normal cells are more circular. Sickle cell starts off by people with sickle cell trait have red blood cells that have normal hemoglobin A, and abnormal hemoglobin. The abnormal hemoglobin is called hemoglobin S. People with sickle cell trait have more hemoglobin A than hemoglobin S. They have enough hemoglobin A to help their red blood cells carry oxygen to the body. There are three common types of sickle traits are, Sickle Cell Anemia (SS), Sickle-Hemoglobin C Disease (SC), and Sickle Beta-Plus Thalassemia and Sickle Beta Thalassemia. How exactly does someone get sickle cell? Sickle is a hereditary trait. For example, my aunt has the trait and my mom does not. My sister and I likewise do not have the trait but there is a good possibility that one of our children can. My aunt met someone else who also has the sickle cell trait and they had two children. Only one of their children has the sickle cell disease. Everyone one in four children will get the sickle disease. If one parent has sickle cell disease and the other parent doesn't have the disease or trait then none of their children will have the disease but will have the trait There can be several complications starting off which can lead up to bigger issues. The red blood cells can cause......

Cystic Fibrosis is a major factor which can affect the patterns and trends of ill health in the UK. In the future it is expected that over 2 million people in the UK will carry the gene. Thalassemia- Is a group of inherited disorders where part of the blood otherwise known as haemoglobin is abnormal. This means that the red blood cells that are affected are unable to function properly, this can cause anaemia. In thalassemia the production of haemoglobin is abnormal, of which can lead to anaemia due to the reduction of oxygen being carried around the body. The symptoms include feeling tired, breathless, drowsy and faint. If thalassemia is left untreated, it can cause a variety of complications of which include: organ damage, restricted growth, liver disease, heart failure and death. Thalassemia is a condition inherited from your parents, however there is now known reason as to what causes the genetic mutations of which are associated with thalassemia. Thalassemia can be diagnosed through a series of blood tests and DNA tests in order to determine the type of thalassemia. Pregnant women for example have a routine check-up to look to see if they have an inherited disorder such as sickle cell anaemia. Treatments for the disorder can include bone marrow transplants and cord blood transplantations. However the procedures can cause a variety of......

Sickle Cell Disease

...hemoglobin or “beta-thalassemia” hemoglobin as noted by (Rees, Williams & Gladwin, 2010). Types of Sickle Cell Disease The disorders; sickle cell anemia disease (caused by “S” hemoglobin), “SC” disease (caused by “SC” hemoglobin and “S-beta thalassemia” (caused by “beta-thalassemia” hemoglobin) are collectively referred to as sickle cell disease (Rees et al, 2010). The most common form of Sickle cell disease is the Sickle cell anemia. Sickle beta-thalassemia is less common but can be either mild or severe while hemoglobin S-C disease is milder than Sickle cell anemia. Inheritance of Sickle Cell Disease Red blood cells disorders as noted above are genetically transferred to children from parents, each with abnormal hemoglobin. The message in the genes that determines the type of hemoglobin is passed on to the child through the mother’s egg and the father’s sperm (Peterson, 2008). The Sickle cell disease affects children whose parents are both carrying the sickle cell trait or one has a sickle cell trait (AS) and the other has the sickle cell disease (SS). An individual with sickle cell trait has got one sickle hemoglobin gene (S) and a normal hemoglobin gene (A). Such individual do not suffer from sickle cell disease in their lifetime but rather sickle cell trait remains as a condition. In sickle beta-thalassemia, one parent possess sickle cell anemia or sickle cell trait with the other parent having thalassemia major or beta thalassemia......

Sickle Cell Anemia

...Chromosome (11p15.4 specifically and its locus MIM number is141900), provides “Instructions “ for making the beta globin but unfortunately nothing in life is perfect and mutations are bound to occur. Various versions of Beta Globin result from different kinds of mutations in the HBB gene. Some mutations in the HBB gene lead to abnormal versions of beta globin such as hemoglobin C (HbC) and hemoglobin E (HbE). HBB gene mutations can also result in unusually low levels of beta-globin; this abnormality is called beta thalassemia .One particular mutation produces the abnormal HbS Beta globin. People with sickle cell disease, at least one of the beta globin subunits in hemoglobin are replaced with hemoglobin S. For example, people with sickle hemoglobin C (HbSC) disease have hemoglobin molecules with hemoglobin S and hemoglobin C instead of beta globin If mutations that produce Hemoglobin S and beta thalassemia occur together, individuals have hemoglobin S-beta thalassemia (HbSBetaThal). In people with Sickle Cell Anemia, both Beta Globin subunits of Hb are replaced with HbS. Since both Beta Globin Subunits of Hb must be replaced, Sickle Cell Anemia is considered as an Autosomal Recessive disease. That means that in order for the Chromosome to be infected, both parents must pass this trait to their offspring. This is the effect at the DNA Level This is the effect at the protein Level This is the effect at the Cellular level (Doughnut shaped (Normal) become Sickle Shaped......

Sickle Cell Anaemia

...Sickle cell disease is a molecular disease of Haemoglobin (Higgins, Eddington, Bhatia, & Mahadevan, 2007). The disorders of hemoglobin (haemoglobinopathies), can be divided into two main groups: the structural variants - HbS, HbC and HbE (Alanazi et al., 2011) and disorders of production of the globin chains which leads to thalassemia. The mutant haemoglobin HbS, HbC and HbE are associated with the sickling disorder. The abnormal hemoglobin is less soluble than normal haemoglobin A and, therefore, tends to crystallize out resulting in deformation of the cells which instead of being disc-shaped become sickle-shaped. Sickle cell disease is inherited as an autosomal recessive characteristic. The disease manifested in persons who are homozygous for the gene. If the mutant haemoglobin is inherited from both parents, the genotype of such offspring will be HbSS, HbCC or HbEE. But if from only one parent, the genotype would be heterozygous HbAS, HbAC or HbAE. Also, an offspring can be compound heterozygote e.g. SC and SE among others (Weatherall, Akinyanju, Fucharoen, Olivieri, & Musgrove, 2006) The molecular basis for erythrocyte sickling is a single nucleotide substitution in codon 6 of the β-globin gene leads to an amino acid substitution (Glu→Val) that is responsible for the sickle mutation in beta-globin (β S), which forms the abnormal HbS tetramer (Kazazian et al., 1992). Upon deoxygenation, HbS undergoes rapid intracellular polymerization with subsequent cellular dehydration,...

Building Baby from the Genes Up

...behaviors of a person and can cause the person to have more or less of some specific traits. He argues that for some specific conditions, the modification of genes can be acceptable, as it would result in making better that person to live with enough confidence in the society. He discusses several examples or realistic projects related to behavioral genome techniques, in which, traits of people were modified through the modification of their genomes. Similarly, vulnerable diseases like thalassemia can also be cured through the modification of genes (Pinker, 2009). In the year 2008, the idea of human genome modification was legally acceptable when two couples were allowed to get their genes modified in order to prevent their kids from having terrible disease of Cancer. If parents have such diseases which are likely to be transmitted in their kids through the genes, they can modify their genes so that their kid would be protected. Not only cancer, but the several terrible diseases like thalassemia, diabetes, and other genetic faults are curable through such techniques. I agree with the facts discussed in the article that, apart from diseases, there are a lot of chances of modifying the appearance of human through the changings in genes. Such as, the color of eyes, teeth, skin, and even hair can be changed through the modification of genes. Moreover, there are chances to enhance the lives of persons through making experiments on genes, such as, when vulnerable diseases are......

...issue. THALASSEMIA Thalassemia is a blood issue went down through families (acquired) in which the body makes an anomalous type of hemoglobin, the protein in red platelets that conveys oxygen. The issue results in exorbitant annihilation of red platelets, which prompts sickliness. Pallor is an issue in which body doesn't have enough ordinary, sound red platelets (RBC).This sickness is acquired, implying that no less than one of the folks must be a bearer of the illness. It is created by either a hereditary change, or an erasure of certain key qualities. The two fundamental types of thalassemia are alpha thalassemia and beta thalassemia. In alpha thalassemia, no less than one of the alpha globin qualities has a change or anomaly. In beta thalassemia, the beta globin qualities are the ones influenced. Each of these two types of thalassemia has a few particular sorts. Thalassemia happens when there is an anomaly or change in one of the qualities included in hemoglobin creation. This hereditary deformity is acquired from the folks. On the off chance that one and only of the folks is a transporter for thalassemia, it may add to a type of the ailment called "thalassemia minor." If this happens, it will most likely not have side effects, but rather it will be a bearer of the sickness Thalassemia minor typically does not create any manifestations. In the event that it does, it causes just minor iron deficiency. Beta thalassemia comes in two genuine sorts which are thalassemia......

Other complications of hemolytic anemia include: pain shock gallstones and other serious health problems Thalassemia An inherited form of hemolytic anemia caused by mutations on either chromosome 11 or chromosome 16, thalassemia stems from the body's inability to manufacture as much normal hemoglobin as it needs. There are two categories of thalassemia, depending on which of the amino acid chains is affected (hemoglobin is composed of four chains of amino acids). In alpha-thalassemia, there is an imbalance in the production of the alpha chain of amino acids; in beta-thalassemia, there is an imbalance in the beta chain. Alpha-thalassemias most commonly affect people of African descent (25% have at least one gene for the disorder); beta-thalassemias most commonly affect people of Mediterranean ancestry and Southeast Asians. The most severe form of beta-thalassemia is also known as Cooley's anemia, named for the American pediatrician who first identified it. Characterized by production of red blood cells that are unusually small and fragile, thalassemia affects only people who inherit the gene for it from both parents. This pattern is called autosomal recessive inheritance. Autoimmune hemolytic anemias Warm antibody hemolytic anemia is the most common type of this disorder. This condition occurs when the body......
