Every person has mutations in their genes. These mutations add to the uniqueness of individuals and most are not harmful. In fact, some mutations can be protective. However, there are some mutations in the DNA that a person is born with that can result in genetic conditions. Some conditions can cause serious health problems.
Genetic research is leading to the development of more genetic tests that can be used for the diagnosis of genetic conditions. Genetic testing is available for infants, children, and adults. Genetic tests can be used to diagnose a disease in an individual with symptoms and to help measure risk of developing a disease. Adults can undergo preconception testing before deciding to become pregnant, and prenatal testing can be performed during a pregnancy. Results of genetic tests can help physicians select appropriate treatments for their patients.
Genetic testing is a type of medical test that identifies changes in chromosomes, genes, or proteins. The results of a genetic test can confirm or rule out a suspected genetic condition or help determine a person’s chance of developing or passing on a genetic disorder. More than 1,000 genetic tests are currently in use, and more are being developed.
Several methods can be used for genetic testing:
• Molecular genetic tests (or gene tests) study single genes or short lengths of DNA to identify variations or mutations that lead to a genetic disorder.
• Chromosomal genetic tests analyze whole chromosomes or long lengths of DNA to see if there are large genetic changes, such as an extra copy of a chromosome, that cause a genetic condition.
• Biochemical genetic tests study the amount or activity level of proteins; abnormalities in either can indicate changes to the DNA that ...

...urance coverage has been denied to many people due to their genetic status. There are many benefits to the insurance companies of knowing people's genetic data, the insurance companies costs could be lowered.
The use of these new techniques raises many ethical issues. Should we screen embryos for genetic diseases? If so what diseases must we screen for? Should we allow couples to select the sex of their child? If genetic test can tell if someone will die young, this can change the way they live. So is it ethical to make him aware of the test results? In spite of these ethical issues and many more, many people believe that most of these problems could be resolved through implementation of regulations that prevent the misuse of this powerful technology.
Genetic testing is a tool that if used properly will be of benefit not only to individuals, but to the whole world!
One of the particular areas of interest is prenatal genetics. In this field, many new and outstanding innovations have been made. A mother and father can now check for a large array of disorders that could occur in their child; sexual preference has now been shifted from the hands of a higher being to that of someone with a Ph.D.; and in the near future, a couple will possibly be able to choose the physical features of their child, such as hair color, eye color, etc. Scientifically speaking, all of these new options that parents have is amazing. Not only can they have a healthy baby, but one that is going to be stronger, and better looking. Yet, ethically speaking, many people would dislike the “playing” of God. And when it becomes possible to create a perfect child, what will prevent us in society from doing so? The field of genetics in prenatal situations has become very advanced over the past few years, yet many of these advancements have given arise to unethical applications.
Advantages of genetic testing may be helpful in determining whether or not you have a disease or are proba...
In Gattaca, the plot focuses on the ethics, the risks, and the emotional impact of genetic testing in the nearby future. The film was released in the 90s; yet in the present, the film does not give the impression of science fiction. Today, genetic testing is prevalent in many aspects of the scientific community. This paper will describe genetic testing, its purpose, diagnostic techniques that use genetic testing, relating Huntington’s disease to genetic testing, and the pros and cons of genetic testing.
Picture a young couple in a waiting room looking through a catalogue together. This catalogue is a little different from what you might expect. In this catalogue, specific traits for babies are being sold to couples to help them create the "perfect baby." This may seem like a bizarre scenario, but it may not be too far off in the future. Designing babies using genetic enhancement is an issue that is gaining more and more attention in the news. This controversial issue, once thought to be only possible in the realm of science-fiction, is causing people to discuss the moral issues surrounding genetic enhancement and germ line engineering. Though genetic research can prove beneficial to learning how to prevent hereditary diseases, the genetic enhancement of human embryos is unethical when used to create "designer babies" with enhanced appearance, athletic ability, and intelligence.
There are many types of genetic tests that are administered to the adult population. The more commonly used genetic tests are paternity tests, genealogical tests, and forensic testing. They are quite self-explanatory; paternity tests are to determine relatedness of 2 subjects, genealogical tests are used to formulate a heritage or ancestry, and forensic testing is used to identify or rule out a person that has been charged with a crime. Other genetic tests include presymptomatic testing, used to determine the risk someone has to developing a genetic disorder, diagnostic screening, used to rule out or identify a suspected condition, and carrier screening, used to determine if an individual carries one copy of a gene mutati...
When it comes to genetic diseases and conditions, testing can be very helpful and serve a good purpose. People with diseases that are inheritable to their children are encouraged to be tested. For example, in the article about Jewish testing, it says
The Human Genome Project is the largest scientific endeavor undertaken since the Manhattan Project, and, as with the Manhattan Project, the completion of the Human Genome Project has brought to surface many moral and ethical issues concerning the use of the knowledge gained from the project. Although genetic tests for certain diseases have been available for 15 years (Ridley, 1999), the completion of the Human Genome Project will certainly lead to an exponential increase in the number of genetic tests available. Therefore, before genetic testing becomes a routine part of a visit to a doctor's office, the two main questions at the heart of the controversy surrounding genetic testing must be addressed: When should genetic testing be used? And who should have access to the results of genetic tests? As I intend to show, genetic tests should only be used for treatable diseases, and individuals should have the freedom to decide who has access to their test results.
Before we start discussing how genetic tests are developed, let us discuss how genes can trigger disease. A sound body requires the action of many proteins working together. For a protein to function properly, an intact gene must encode for that specific protein. A mutation describes a gene which has been changed. The most common type of mutation is a single change of a nucleotide of DNA. Other types of mutations include the loss or gain of a nucleotide and the disappearance or multiplication of long segments of DNA. Mutations can have three effects: beneficial, harmful, or neutral. Mutations are beneficial if the fitness of an individual is enhanced. Harmful mutations can either slightly alter a protein, where the protein may still minimally function, or they may totally disable a protein. In this instance, the outcome is not only based on how a mutation alters a protein’s function, but on how important the protein is to the body (Understanding Gene 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 is the process of sequencing six billion letters of a human genome to possibly discover genetic differences, such as how cells carry the same genome but at the same time look and function different. Genetic testing is also the process that can give foresight into pathological diseases such as different types of cancer.
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.

Genetic testing has become very popular as technology has improved, and has opened many doors in the scientific community. Genetic testing first started in 1866 by a scientist known as, Gregor Mendel, when he published his work on pea plants. The rest was history after his eyes opening experiments on pea plants. However, like any other scientific discovery, it bought conflicts which caused major controversies and a large population disagreed with the concept of playing with the genetic codes of human beings. Playing God was the main argument that people argument that people had against genetics. genetic testing became one of the major conflicts conflicts to talk about, due to the fact that parents could now have the option of deciding if they
Most diseases are caused by a type of genetic component. Many of the diseases that have been caused by gene mutations are undiagnosed. These remain undiagnosed because the disease is so rare that the doctor does not know how to diagnose the patient. Many sy...
Bioethics is a reflection of controversial moral choices or decisions pertaining to medical and healthcare fields. There have always been ethical standards in healthcare handed down within each profession. Although ethical decisions of the past were followed without question, bioethics today is constantly debated among those in the medical field, the general public, and those in governmental positions. Technological advances within the last century have opened the door to discussion about the ethics surrounding the last medical and technological advances. The decisions are influenced by culture, religion, philosophy, and personal preference. Bioethical decisions are always open for questioning. It is even possible for issues to be ethical during one decade and upon review, deemed unethical several years later. It is the job of the medical community and the public to question these issues, debate them, and accept or reject them. Although there have been hundreds of people who have influenced bioethics through their technological advances, Sir Robert Edwards’ invitro- fertilization techniques have changed the way many women today can become a mother.
