Transcript of Genetic Testing

What is Genetic Testing? Genetic testing is a type of medical test that
identifies changes in chromosomes,genes, or
proteins. The History Of Genetic Testing Three Ways of DNA Testing -Genetic screening is done for a particular condition in individuals, groups or populations without family history of the condition.
-Genetic testing is done for a particular condition where an individual is suspected of being at increased risk due to their family history or the result of a genetic screening test.
-Direct gene testing looks at the presence or absence of a known gene mutation by examining the sequence of letters in the information in the gene. ~The most common form of DNA analysis is called polymerase chain reaction (PCR). Cells were first discovered in plant and
animal tissue in 1665 and in 1839. Cells
containing nuclei were recognized
as the building blocks of life. It was also
recognized that cells could only be
formed through the dividing of other
cells. Genetic Testing By: Sandra Gutierrez Why Do People Get Genetic Tests? People get genetic tests because they want to find out if they will have diseases In the future. They also get them because they want to find out about their genetic issues. ~The other two methods used to analyze DNA evidence are restriction fragment length polymorphism (RFLP) testing and PCR testing on DNA from the mitochondria of the cell. Work-Cited Page http://www.ojp.usdoj.gov/ovc/publications/bulletins/dna_4_2001/dna7_4_01.html https://ezinearticles.com/438498 How accessible are these methods
to the public (individuals) or agencies? http://www.tree.com/health/genetic-health-pros-cons.aspx http://www.hhs.gov/myhealthcare/genetictests/genetictests.html#breastcancer Example Case About Genetic Testing What does the future hold for DNA testing and How Does it Affect Genetic Testing? Other Miscellaneous or Interesting Facts and/or Data? What does the future hold for DNA testing?
continued, Things of The Future:
~DNA chips are finding applications throughout the field of molecular biology. http://www.ornl.gov/sci/techresources/Human_Gene/medicine/genetest.shtml#more It affects it because in order for DNA to be found researchers/doctors have to get blood types. I also think that you find your blood type in your genes. ^Jane, a 50 year old woman, has been diagnosed by her physician with an advanced form of breast cancer. Her doctor recommends that she start chemotherapy immediately. After a number of weeks, however, she does not respond to treatment. ^Jane’s doctor promptly takes a biopsy, and instructs the laboratory at the hospital to test the tissue sample for Her2/neu activity. The lab results indicate that Jane’s biopsy sample shows an overproduction of Her2/neu. ^Jane and her physician discuss this new information, and further medical interventions are determined. The team decides that in Jane’s specific case, chemotherapy should be continued, but that Herceptin® would be effective as part of the treatment for Jane’s cancer. ^Weeks later, her physician reports that her tumor is responding to the new treatment program. The genetic test helped Jane’s physician tailor her treatment, and avoid some of unpleasant side effects that her prior treatments had caused. http://www.redcrossblood.org/learn-about-blood/blood-types
~Anyone can get a Genetic Test at any local clinic. You will need parent verification in some clinics if you do everything legally. Some of the states where you can get a test.
