Genetic testing is a type of medical test that identifies the changes in chromosomes, genes, or proteins. The results of a genetic test can confirm or rule out a genetic condition and if it can be passed on. I feel that genetic testing’s pros outweigh the cons. The physical risks of the genetic testing are very small. A positive result of genetic testing can help a person maintain prevention, and treatment options. Some test results can also help people make decisions about having children. Newborn genetic screenings can help identify genetic disorders early in life so treatment can be started as early as possible so that the unwanted gene will not pass on. Most of the opinions in the genetic testing seminar were on the positive side, choosing that it should be used more often. The generic testing can help better prepare people for what they can pass down if they choose to have children. For example, if someone has the high risk of diabetes running in their family their most likely to have it passed down to their children and even getting it themselves. I think the majority of people want to know what their genes carry, because it can have a huge impact on their life. Technological advances in genetic testing lend parents new insight about their children's risk factors for developing diseases later in life. The issue has been the subject of heated debate as parents grapple with the pros and cons of testing themselves and their children. Genetic testing can help people determine why they get cancer or other diseases. Genetic testing is recommended to people who have a family history of a genetic disease, have children who are born with genetic defects, and have gone through more than one miscarriage in the past. Though these te... ... middle of paper ... ... idea to take part in. Genetic testing can lead to a global preparation for parents to look out for their children. The genetic test results can determine so much for the children and what they might get passed down to them whether its diabetes, cancer, or any other illness or disease. For example, if someone is of Jewish descent have a higher prevalence of harmful BRCA1 and BRCA2 mutations than people in the general population. Other ethnic and geographic populations around the world, such as the Norwegian, Dutch, and Icelandic peoples, also have higher prevalences of specific harmful BRCA1 and BRCA2 mutations. In addition, limited data indicate that the prevalence of specific harmful BRCA1 and BRCA2 mutations may vary among individual racial and ethnic groups in the United States, including African Americans, Hispanics, Asian Americans, and non-Hispanic white.
. DNA can be left or collected from the hair, saliva, blood, mucus, semen, urine, fecal matter, and even the bones. DNA analysis has been the most recent technique employed by the forensic science community to identify a suspect or victim since the use of fingerprinting. Moreover, since the introduction of this new technique it has been a large number of individuals released or convicted of crimes based on DNA left at the crime sceneDNA is the abbreviation for deoxyribonucleic acid. DNA is the genetic material found in cells of all living organisms. Human beings contain approximately one trillion cells (Aronson 9). DNA is a long strand in the shape of a double helix made up of small building blocks (Riley). There are four types of building
The public should be aware of what could happen if this kind of information became public knowledge, and of the opportunities that the knowledge brings. There is no doubt that the information from genetic analysis is going to help a lot of people with all sorts of problems live longer and healthier lives. The only problem is that we have to keep the information in the hands of those who need it, and out of the hands of those who would use the information to profit or discriminate.

By using identified gene mutations that are known to cause diseases, asymptomatic individuals are able to discover if they are at risk for specific genetic conditions; this is known as genetic testing. Unfortunately, genetic testing can vary in its predictive ability. For example, Huntington disease, Duchenne Muscular Dystrophy, Fragile X syndrome and multiple endocrine neoplasia type 2 are conditions that can be determined by genetic testing (Samen, 1996). In contrast, for multifaceted diseases like Alzheimer’s, breast and ovarian cancer and colorectal cancer, predisposition can be determined with genetic testing. However, an absolute diagnosis of those diseases cannot be made (Heshka et al., 2008).
Due to the human genome project and other genetic research, tests for mutation which cause diseases have been developed. The list of these illnesses include several types of cancer. Doctors have estimated that as many as 3,000 diseases are due to mutations in the genome. These diseases include several types of colon cancer in which three different genetic tests have been already developed. Debates have arisen on whether these tests should be used regularly or not. Questions including the patients= rights of privacy and the possibility of loss of health or life insurance have been argued over in both the media and political arena.
There are numerous risk factors for breast cancer. Genetics or family history of breast cancer in a one first-degree relative with breast cancer doubles a woman’s risk. Having two first degree relatives rises a woman’s risk by three times. A person’s personal history who have had one breast with cancer is three to four times as likely of developing a new cancer. White women are slightly more likely to develop breast cancer than are African-American women, but African-American women are more likely to die from this cancer. However in women under 45 years of age, breast cancer is more common in African-American women.
Genetic testing involves examining an individual’s DNA and identifying abnormalities within the chemical makeup of specific structures. It, essentially, maps the person’s genome and can be interpreted to predict future issues. By analyzing the chromosome, genes, and even certain proteins, physicians and researchers can find changes that lead to inheritable disorders. These changes can lead to possible diagnosis or cure for the disorder in question. In most cases, genetic testing is used to determine the probability that an individual will develop a certain disorder. It is not used to specifically diagnose a disorder, as there are no techniques that are 100% accurate. Genetic testing techniques do give good evidence to confirm a physician’s findings, but it is not the first act a physician takes to diagnose a disorder. It can narrow a search or rule out a specific disorder very confidently, but making a diagnosis based solely on genetic testing is not an action that a qualified medical professional would consider.
Genetic testing has been a very controversial topic. While some people believe that genetic testing is completely right in any situation, others believe that it is completely wrong in any situation. However, both sides prove valid points of why genetic testing is both right and wrong. Genetic testing can be very good when it is being used for helpful reasons. However, genetic testing can also be very bad when it is used for the wrong reasons. Genetic testing is okay to do as long as it is being done for the right reasons and following good moral guidelines.
First, let's consider the situations in which genetic testing would be beneficial to patients. Genetic testing for diseases that are preventable or treatable could allow individuals to alter their lifestyles so as to treat the disease or reduce their risk of developing the disease. For instance, the E2 version of the APOE gene, which is found on chromosome 19, has been linked to heart disease (Ridley, 1999). Individuals who have two copies of the E2 gene are particularly sensitive to high-fat and high-cholesterol diets. Therefore, a genetic test to determine whether a person has the high-risk version of the APOE gene could inform a person of future health risks, thereby allowing the person to change his diet to help prev...
Within the past thirty years, researchers have found strong evidence linking genes and disease. The development of predictive genetic tests followed shortly after the isolation of certain candidate genes. Although predictive genetic screening is only available for a handful of diseases, its effects and ramifications have become hotly debated issues in a wide range of areas, from government to religion. The debate began in the 1993 when researchers isolated the BRCA1 gene, which is associated with increased risk of developing breast and ovarian cancer. The discovery of this gene led to excitement and speculation of developing a predictive genetic test to identify those women at risk for these cancers. In this paper, I will first describe the biology of genetic testing, and then discuss the pros and cons of predictive genetic testing.
In today’s world, people are learning a great deal in the rapidly growing and developing fields of science and technology. Almost each day, an individual can see or hear about new discoveries and advances in these fields of study. One science that is rapidly progressing is genetic testing; a valuable science that promotes prevention efforts for genetically susceptible people and provides new strategies for disease management. Unnaturally, and morally wrong, genetic testing is a controversial science that manipulates human ethics. Although genetic testing has enormous advantages, the uncertainties of genetic testing will depreciate our quality of life, and thereby result in psychological burden, discrimination, and abortion.
Genetic testing, also known as screening, is a rapidly advancing new scientific field that can potentially revolutionize not only the world of medicine, but many aspects of our lives. Genetic screening is the sequencing of human DNA in order to discover genetic differences, anomalies, or mutations that may prove pathological. As genetic screening becomes more advanced and easily accessible, it presents society with difficult questions that must be asked about the boundaries of science and to what degree we are allowed to tamper with the human genome. To better understand the potential impact of genetic screening on our society, we must examine the potential benefits in comparison to the possible negative impact it may cause. With this knowledge in hand, we can examine what the future holds for this field of study and the best possible direction to take.
Parents now have the possibility of testing genes for mutations and genetic problems (BBC News).
First of all, I want to start by saying that I 'm not discriminating the disabled community, but this is a very large number that could possibly be diminished with the help of genetic testing. (1) I believe that there is nothing wrong with testing the genes of an unborn child to possibly determine if it could develop a genetic disorder in the future. One of the advantages that genetic testing provides is that the parents could now be informed of the situation, and keep track of their unborn child 's health. I 'm sure those parents are pleased with this technology, and the chances to be able to keep track of their baby. This a baby, and is something very precious, and valuable, and I believe that parents want to keep track of anything that may happen with the unborn child. I 'm sure that a large amount of people would agree would agree that they don 't want to suddenly take the hard hit. When the news is presented in the delivery room. This serves more as an advantage than a disadvantage, due to the fact parents. Pull be more prepared, or possibly have the option to abort it. This is a right that the parents should have regardless of the opposing side arguments towards it. Im a hundred percent sure that the opposing side has very strong arguments towards genetics testing, and one of the main ones is "playing God." The opposing side believed that some things in
What are the advantages and disadvantages of genetic engineering? To start with, genetic engineering is another term used for genetic manipulation, which is a process consisting the addition of new DNA to an organism. The whole purpose of this process is to add new traits that are not already available in the organism. Genetic engineering is often mistaken for breeding, which is a technique that is mostly used with animals in order to create faster or stronger offspring. Genetic engineering is however different from breeding because it uses much less natural techniques that are usually performed in the lab.
