Genetic testing is a class of medical testing that recognize changes in chromosomes, gene or proteins. This type of test look for abnormalities in DNA or RNA that is collected from a person’s blood, body fluids or tissues. Genetic testing scans the genes looking for large or small change that occur to gene. These changes to the genes could have missing or addition parts that could change the chemical base within the DNA strand. Abnormal genes could be the result of other mistakes like the genes are too active, they are turned off, or those that are lost entirely. Having abnormal results on genetic testing could mean that a person is prone in having a genetic disorder. There are different types of genetic testing for adults and embryos…show more content…
o FISH analysis (fluorescent in situ hybridization) uses fluorescent DNA probes to recognize certain areas on chromosomes. This test can be used to find small mistakes that was overlooked by the karyotype test. A great example in the use of this test would be discovering missing fragments of DNA on chromosome 22 which has features of velocardiofacial syndrome.
• DNA sequencing is a genetic testing that was mentioned in the movie it is used to figure out the right sequences of bases (nucleotides C, A, T, and G) in the gene of the person being tested. This test is used in the detection of the breast cancer genes BRCA1 and BRCA2.
• Pre-implantation testing is a used on embryos which is also called pre-implantation genetic diagnosis (PGD). PGD detects genetic abnormalities in embryos that were created by a method called in-vitro fertilization (IVF). This method consisted of removing egg cells from a woman ovaries and then unite it with sperm cells outside the body. Pre-implantation is then tested by taking a small number of cells from the embryos and testing them for certain genetic disorders. To achieve a healthy pregnancy only the embryos without the genetic disorders are inserted back into the uterus.
• Prenatal testing is a test used to recognize changes in a baby’s genes before birth. If it is detected that a baby will have an increased risk for a genetic or chromosomal disorder this test will be
