Genetic Testing and Screening Essay

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.

Genetic profiling is a contemporary issue relating to the individual and technology which restricts access to unbiased decisions and privacy. Genetic profiling interferes with the individuals bodily, genetic and behavioural privacy, as it can be used for the benefit of identifying bodies to using the results of a DNA test to choose whether to employ one individual over another, due to future concerns. It can easily be argued that genetic profiling is in the need of law reform as a result of legal implications and the lack of individual’s rights.

Genetic testing is when tests are done on the blood and other tissue to find genetic disorders in an individual. It is used as a healthcare tool to detect gene variants associated to a certain disease or disorder, and is used non-clinically for paternity testing and forensics. There are many different methods of testing, usually done with a blood sample. Other methods include diagnostic testing, carrier testing, prenatal testing, pre-implantation genetic testing, newborn screening, pharmacogentic testing, and a few others.

The records have been reviewed. The member is an adult female with a birth date of 05/12/1964. She has a diagnosis of early stage colon carcinoma. Her treating provider, Stephen Grabelsky, MD recommended the Oncotype DX Colon Cancer Assay.

The BLS states that the employment outlook for the genetics counseling field is quite promising. They project it to grow at 29 percent until the year 2024, which is much faster than average. Keep reading to learn why the employment outlook for this exciting medical field is so good.

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

In this critique, I will be discussing my opinion on Mr. Pollard’s article about genetic screening. These genetic screening began in the 1960’s and since then they have found themselves in the middle of major controversy throughout the years (Press, 2008). Genetic screening a series of test performed when a mother is pregnant in order to figure out whether or not her child may have a developing disorder. Some genetic screening are also performed after the baby is born. Genetic screening can play a major role in personal parenting decisions and medical treatment if and when deemed necessary. Although genetic screening has much debate surrounding it, testing for any potential disorders and diseases can be live saving.

Prenatal genetic testing has become one of the largest and most influencial advances in clinical genetics today. "Of the over 4000 genetic traits which have been distinguished to date, more than 300 are identifiable via prenatal genetic testing" (Morris, 1993). Every year, thousands of couples are subjecting their lives to the results of prenatal tests. For some, the information may be a sigh of relief, for others a tear of terror. The psychological effects following a prenatal test can be devastating, leaving the woman with a decision which will affect the rest of her life.

. Examples of carrier screening include sickle cell anemia, Tay-Sachs disease, duchenne muscular dystrophy, hemophilia, Huntington's disease, and neurofibromatosis. Forensic screening seeks to discover a genetic linkage between suspects and evidence discovered in criminal investigations. This is a very powerful tool to clear the innocent and convict the guilt. Since DNA is unique, many people are reluctant to see such information become part of any national database, which might include information not only about identity but also about proclivity toward disease or behavior. Susceptibility screening involves the screening of selected populations for genetic susceptibility to environmental hazards. Helps to identify workers who may be susceptible

An individual ethnicity play a vital role in genetic testing. Racial and ethnic difference can relate to the cause, expression and prevalence of certain diseases. In some ethnic group there is an increased propensity for certain genetic disorders and knowing an individual’s ethnicity can provide additional information during genetic testing.

To screen, or not to screen, is the question. 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, help determine a person’s chance of developing or passing on a genetic disorder or link up and reunite lost family lineage, ties (Sofge, 2014). For instance, the American reality TV star Snooki once thought she was Italian-American but her skin color was too dark. A genetic test showed that she had been adopted and her parents came from Chile instead. Regardless of the myriad benefits of genetic testing in solving various human mysteries and identification of people in criminal cases (innocent or guilty),

Preimplantation genetic diagnosis or PGD is the process of genetic testing of an embryo for serious genetic diseases before implanting it in the uterus. IVF or In Vitro Fertilisation is the manual fertilisation of an egg by adding sperm in a laboratory and then added into the uterus. Both of these procedures are used internationally for many couples who rely on this technology to be able to have children.

Everyone with any mental health disorder always wonders if genetics can be linked to the disorder they have. It has been said that risk of genetics being a factor in anxiety disorders is less likely to be a switch more than a problematic mix of genetics that can put a person at risk. Researchers have said that anxiety disorders can be due to hostile childhood experiences. Efforts identifying the specific DNA mutations to the heritability of anxiety disorders establish any independent suspicious loci, but any genetic study for anxiety faces some obstacles also. The fine line between healthy and pathological anxiety is unclear, and the phenotypic and genetic barriers between scientific anxiety disorders are confused. People have often

Some might say in response to the above announcement, “This is positive medical news—both for Iceland and the world. Nothing here should concern the American public. Genetic testing for abnormalities saves children from a life of significant disability and spares their parents painful stress. The subsequent abortions avoid a wretched existence for the children and improves the quality of life for their surviving families. That is not genocide; it is compassion and mercy. Moreover, it relieves both the parents and society from having to shoulder severe medical expenses for care. That reduces insurance rates and liberates medical resources for those who really need them. So
