By the end of the case study I will generate a person opinion on whether I support gene screening or don't and a reason for my suggestion. WHAT IS GENE-SCREENING? Genetic testing is a type of medical test that identifies changes in chromosomes, genes, or proteins. Most of the time, testing is used to find changes that are associated with inherited disorders. 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. ...read more.


In some cases, prenatal testing can lessen a couple's uncertainty or help them make decisions about a pregnancy. It cannot identify all possible inherited disorders and birth defects, however. III PAGE THREE: TYPES OF GENE-SCREENING Pt 2. Preimplantation testing Preimplantation testing, also called preimplantation genetic diagnosis (PGD), is a specialized technique that can reduce the risk of having a child with a particular genetic or chromosomal disorder. It is used to detect genetic changes in embryos that were created using assisted reproductive techniques such as in-vitro fertilization. In-vitro fertilization involves removing egg cells from a woman's ovaries and fertilizing them with sperm cells outside the body. To perform preimplantation testing, a small number of cells are taken from these embryos and tested for certain genetic changes. Only embryos without these changes are implanted in the uterus to initiate a pregnancy. Predictive and presymptomatic testing Predictive and presymptomatic types of testing are used to detect gene mutations associated with disorders that appear after birth, often later in life. These tests can be helpful to people who have a family member with a genetic disorder, but who have no features of the disorder themselves at the time of testing. ...read more.


Unlike other types of genetic testing, a parent will usually only receive the result if it is positive. If the test result is positive, additional testing is needed to determine whether the baby has a genetic disorder. Before a person has a genetic test, it is important that he or she understands the testing procedure, the benefits and limitations of the test, and the possible consequences of the test results. The process of educating a person about the test and obtaining permission is called informed consent. Preimplantation testing V PAGE FIVE: Is Gene-screening effective? There are many arguments contributing towards gene screening being bad or good. On this section there are going to be arguments evidences for genescreeing. Some arguments for gene screening: Gene- screening is good as it can help find the rarest diseases and put an end to them Can help stop an epidemic and help stop the spread of diseases. Can help make the human kingdom more secure from harmful and powerful diseases. Can increase a new born babies life spam. Will help further generations not contract diseases. Can help Couples/parents find out that they are carriers. Gene-screening helps as it ca ?? ?? ?? ?? ...read more.
