Genetic disorders Essays

A genetic disorder is a topic in Science that cannot be avoided. The fact is that genetic disorders can happen in humans, plants or animals, to date no form of life is documented as being safe from a genetic disorder. A genetic disorder can appear in the beginning stages of life or can appear much later in life when least expected. A fundamental principle of biology states that the behavior of chromosomes during the meiosis process can account for genetic inheritance patterns (quote). There are many

individual’s genome are known as genetic disorders which are either inherited or caused by mutation in the pre-existing genes (Shiel, 2010). Genetic disorders can be categorized into four classes which are single-gene disorder, multi-factorial inheritance, chromosomal inheritance and mitochondrial mutations. (Refer to Figure 1, Appendix 1). Each disorder is further discussed based on their characteristics and diseases symptoms. The first type of genetic disorder is the single-gene

Genetic disorders are caused by an abnormality in our DNA. One genetic disorder that affects many lives, whether it be ourselves or someone we know, is Cancer. Cancer is caused by uncontrollable cell division. There are over 100 different types of cancer that we know of. There are many risk factors that can lead to getting cancer. Some of these things may be genetic, but some are also environmental including smoking and pollution. Cancer can affect us in many ways.Cancer can affect many parts of

Genetic Basis Achondroplasia is a genetic disorder in that cartilage is not able to form into bone during development. There is a genetic mutation that happens in Chromosome 4. The mutation that happens is in the FGFR3 gene, which codes for the development of the protein Fibroblast Growth Factor Receptor 3. This protein aids in developing bone tissue and in this mutation the protein becomes overly active (Rosseau et al. 1994). There are two 2 mutations in the FGFR3 Gene that can happen (Pagon et

Genetic Disorder and Genetic Mutation: “A genetic disorder is a disease that is caused by an abnormality in an individual's DNA. Abnormalities can be as small as a single-base mutation in just one gene, or they can involve the addition or subtraction of entire chromosomes.” [Source: Learn. Genetics. Website. http://learn.genetics.utah.edu/content/disorders/ Accessed: 25 February 2017] Gene Mutations occurs in 3 ways: Insertion: adding an additional base pair to the DNA sequence. Deletion: deleting

Haemophilia A is an X-linked recessive disorder and is caused by an inherited genetic mutation that is a permanent alternation in the DNA sequence which makes up a gene. This means that some of the body processes will not work in a normal way. The DNA molecule is packaged into a thread – like structure called chromosomes and they are responsible for carrying genetic information in the form of genes. There are two types of sex chromosomes: the X chromosome and the Y chromosome. All humans have a pair

decision to strip Jonathan Jackson of his job because of his genetic disorder, Haemophilia. They believe that Jonathan Jackson will be unable to function in his role as an air traffic controller. It will also investigate whether their employers should be given the right to make decisions based on their medical information from their DNA and then make this information available to other future employers. Haemophilia is a rare bleeding disorder in which the blood doesn 't clot normally. If someone has

Genetic disorders booklet: polydactyly Q. Who first discovered the genetic disorder? How was it discovered? A. Tyler Steven Hayden was the one who discovered the disorder. Q. is the disease state dominant or recessive? Explain. A. polydactyly is a dominant but rare disease, it’s caused by a dominant allele of a gene. It can also be passed down if one of the parents have the disorder. Q. Differentiate between recessive and dominant disorder? Explain. A. your genes

The human body is inherently flawed. Every person, no matter their background, is born with a couple of genetic disorders, whether they are visible or not. However, scientists have come to a point where they might be able to alter and correct these genetic disorders through the application of gene therapy, where a disorder or disease is corrected by the insertion of a gene into a cell rather than using antibiotics (“What is Gene Therapy”). Despite the extraordinary benefits gene therapy could have

be a very controversial topic, as there is still a lack of knowledge surrounding this type of medical treatment. Most people do not understand what gene therapy actually entails or any of the safety issues involving this type of treatment for genetic disorders. With more research and understanding increased clarity can be gained (NLCAP,

become disrupted and mutated. Genes make people who they are; they are the functional unit of heredity. Defective or missing genes or chromosomal abnormalities cause genetic disorders. Some biologists assume genetic disorders or hormone imbalances cause psychopathic tendencies in people. An example of a genetic disorder is the XYY disorder. This is when a male is born with two Y-chromosomes; with the addition of an extra chromosome the male is prone to exhibit aggressive tendencies. This is something

genes to treat illnesses and other disorders. The science of gene therapy works by attaching a properly functioning gene to a virus, or viral vector, to further be inserted into the cell that is perceived as damaged. One specific virus used is a retrovirus, which, according to those at the Genetics Home Reference, “integrate[s] their genetic material (including the new gene) into a chromosome in the human cell.” The retrovirus then modifies the cell’s genetic makeup, and, if the process is effective

September 14th, 1990. The patient was born with a genetic disease called Severe Combined Immunodeficiency (SCID), which drastically impaired her immune system. Children with SCID rarely make it to adulthood as their weakened immune systems cannot handle the most mild of infections. In response to this case, doctors removed white blood cells from the

Gene therapy is a technique that is still in the experimental stages. It uses genes to treat or prevent disease. They are hoping that in the future gene therapy will help doctors treat a disorder by inserting a gene into a patient’s cells rather than using drugs or surgery. Researchers are trying many different approaches to gene therapy. Some include, Replacing a mutated gene that causes disease with a healthy copy of the gene, Inactivating, or knocking out a mutated gene that is functioning improperly

Cystic Fibrosis is a serious genetic disorder that affects the insides of a human body. Cystic Fibrosis is a genetic condition in which the lungs and the insides of the human body become clogged with thick sticky mucus. The mucus builds up inside of the body and affects the insides like the lungs, liver , pancreas, your sinuses, and more. Cystic Fibrosis also affects the digestive system which makes food harder and a longer time to digest. Some symptoms for cystic fibrosis are salty-tasting skin(sweat)

depression is an illness. However, depression is a serious medical illness that has a significant impact on the lives of people. Also, depression does not only affect people physically but also emotionally, and depression is not just feeling sad. it is a disorder defined by thoughts, behavior, and feelings. Nowadays, there are more than million people in the united states of America who have been diagnosed with depression. Those with depression might have a hard time understanding what they are experiencing

Bipolar disorder sometimes referred to as manic depressive disorder is a type of affective disorder, characterized by cyclical episodes of mania and depression. Depression is categorized as a loss of energy, disrupted sleep, feeling down or empty, impaired thinking, and lack of interest and pleasure. Mania is categorized by increased energy, decreased need for sleep speeding thoughts, disorganized thinking, and speech is pressured, and heightened senses that can lead to agitation. Bipolar disorder has

Galactosemia is a type of genetic disorder that modifies the process of breaking down galactose, a simple sugar. Galactose is essentially part of a common sugar named lactose. Furthermore, it can also be present in a variety of foods, especially in baby formulas and dairy products. “Galactosemia” is a term that represents that the blood contains too much galactose. There are several types of galactosemia, such as classic and clinical variant galactosemia (type I), galactokinase deficiency (type

Haemophilia A is an inherited genetic disorder which causes a bleeding tendency, mainly into joint spaces. This is due to the inadequacy of clotting, (L.A.Valentino et al 2012). This disease is developed from a mutation of the gene F8 which contains information on how to make the protein, coagulation factor VIII in the plasma which contributes to blood clotting. Therefore the disruption of this process leads to prolonged bleeding, (Konkle BA, Josephson NC and Nakaya Fletcher S, 2000). The key symptom

The genetic disorder I chose to study is color blindness. Being Color blind is actually very common for men and not as much for women. Color Blindness affects one in twelve men and one in two-hundred women. Color Blindness is also known as color vision deficiency or CVD, and is stated in the article, "Color Blindness" by Utah Eye Centers, that it is "an abnormal condition characterized by the inability to clearly distinguish different colors of the spectrum." That just basically means that some colors
