DNA Chip - Genetic Testing of the Future Essay

The medical advances being made feasible by genetic testing are very exciting. It is possible for people with predispositions for genetic defects to know in advance if they will have a healthy child or not. If they find out there is a problem they can choose to terminate the pregnancy or they can prepare in advance for their child's special needs. There is even new technology called Ex Utero genetic testing. This test is performed on eggs fertilized through in vitro fertilization before they are even put in the mother's uterus. Understanding genes in the developing human will help doctors understand the nature of genetic diseases and may lead to countless other medical breakthroughs. Though it is probably a long way off doctors may one day be able to manipulate genes. If this is possible some genetic problems may be cured.

Genetic testing is used to determine the risk of a patient or patient’s offspring developing genetic diseases. This is done with DNA sequencing in adults and preimplantation genetic diagnosis (PDG) on embryos. These methods of genetic testing are effective means of determining the likelihood of developing diseases such as Huntington’s disease, a disease resulting from trinucleotide repeat on chromosome 4p16.3 that causes uncontrollable muscle movement and decrease in cognitive function. However, they only determine probability, which isn’t an entirely reliable means of knowing whether or not symptoms will arise.

As you can see genetic testing is very important and can affect a child's and parents lives for the better and the worst. Children all over the world have serious genetic diseases that affect their life on a daily. Some of these diseases are Achondroplasia, Down syndrome, and Turner's syndrome. Many believe genetic testing is a good way to test for these genetic conditions before the child is even born, but others think that it can harm the baby very badly and even cause a miscarriage, so they choose not to do this kind of testing. Knowing about the most serious genetic diseases is very important for expecting parents to be informed as well as being

The benefit of genetic science for individuals is that it can determine if the person has a possible genetic disorder and give them

When used in healthcare, genetic testing can show the genetic cause of a disease, confirm a suspected diagnosis of an illness, predict future illnesses, and predict responses to

Genetic testing identifies changes in ones genes and chromosomes. These changes often lead to diagnoses of conditions, disorders, or diseases. Through testing, “one can confirm or rule out a suspected genetic condition or help determine a person’s chance of developing or

Genetic testing, can affect a person’s life in many ways. Genetic testing is a type of medical testing that identifies changes that occur in chromosomes, proteins, and genes. These changes that occur can be associated, and often are associated with inherited

Genetic testing is a medical test of one’s DNA that identifies changes in chromosomes, genes, or proteins. The results of a genetic test can confirm or rule out a suspected genetic condition which can help determine an individual's chance of developing or passing on a genetic disorder. In addition, knowing one’s genetic code can help individuals improve their wellness, prevent the onset of diseases they are at risk for, or lessen the harmfulness of diseases they do contract. NOVA’s documentary on PBS, “Cracking Your Genetic Code” demonstrates what exactly genetic testing is, how genetic testing is performed, and in addition the film showed stories about some individuals that have benefited from these special DNA techniques. The film plot focuses

Embryonic screening allows for the elimination of inherited diseases before birth or a treatment plan before birth. In breast cancer patients, genetic testing allows the physician to know if chemotherapy is necessary, which would expand treatment options. Genetic testing could eliminate years of experimental testing and medication use used to diagnose a new disease. Overall, genetic testing is in alignment with the core medical philosophy that early prevention leads to early treatment, which leads to an overall better outcome for the patient.

Results provided through genetic testing enables doctors to be more informed in terms of their patients; allows regular screening practices, or treatment planning at early stages.

Genetic screening is done with RFLP analysis. RFLP stands for Restriction Fragment Length Polymorphism. RFLP analysis is used to find an identifiable pattern of fragments (an RFLP) that indicates a genetic marker. The genetic marker is unique and is inherited in all people with a disorder or disease. The RFLP comes from a strand of DNA near a suspected gene location that has been cut with a restriction enzyme into smaller pieces. The pieces of DNA are separated using gel electrophoresis into their distinctive bands. The RFLP is a distinctive pattern of the fragments in the gel. All people with the disorder or disease have the RFLP pattern, it is written in stone or in this case, DNA. DNA bands are studied to determine if a person has a disease, is a carrier, has no prior deposition to the disease, or if they will develop the disease in the future. A detailed human map is being developed by scientists worldwide who are contributing information to the human genome project. The human genome project is an attempt to map out every gene on every chromosome of the human genome. It is going slowly, but growth in knowledge of the genome is growing exponentially every year. Along with the growth, we are accumulating knowledge about more

According to Chrystoja and Diamandis (2013), targeted genome testing is less costly than some traditional testing methods, is effective in assisting decision making for certain neoplastic medications and is useful in guiding the proper testing for certain diseases such as Lynch Syndrome. In addition, genetic makeup determines the pharmacokinetics of certain drugs and genome testing may assist in medication therapies. Studies indicate that genetic predisposition determines the effectiveness of 20% to 95% of prescribed medications (Bartlett, 2011). With DNA information, a physician can prescribe a tailored medication treatment that will benefit the

Everyone stands to benefit from the developments made in the field of genetics as everyone is made of genes. Genetics is the study genes and how they influence human biology. Genes are the molecular unit of inheritance found in cells, these genes encode everything about human physiology ranging from eye/hair colour to height, possible mental/physical disorders and so on. The field of genetic testing is concerned with advancements in the study of the functions of individual genes and how they influence living things. Major advances have been made in the study of the genetic structure of humans and external influences to our internal makeup, such as our quality of life and their implications that may have on our physical and mental development.

relatively rare single-gene or chromosomal disorders. But as result of advances in molecular medicine, genetics is now able to provide information about more common and accordingly more costly diseases such as Alzheimer’s disease, cancer, and coronary artery disease. It is the predictive ability of genetic tests for these diseases that makes them especially intriguing in adopting a preventive medicine approach and reducing overall healthcare expenditures.

genetic testing, everything has changed. She notes that clinicians now have the ability to diagnose, treat, and monitor a patient’s illnesses or disease progression in an entirely different manner. This is a far cry from the old medical model of responding to a disease (or defect) only after it appears, and then prescribing the recommended medication or intervention. These genetic medical advances sound miraculous and promising, but the ability to test, screen and provide early intervention does not come without many major ethical dilemmas.
