If I had a genetic predisposition to a deadly illness like cancer or heart disease I would want to know! I do know these test are not like a crystal ball but they do give you a probability percentage of the likelihood of this happening in your life time. If you know you are at 85% at risk to become obese, wouldn’t you want to know so you can take action now. I did some research on genetic testing and there are four types of test. Prenatal testing, Gene Sequencing, SNP Testing and Genome Sequencing. I am interested in SNP Testing for myself. The test costs around 2500 and is not covered by insurance.
TEST DETAILS: SNPs or single nucleotide polymorphisms, are tiny sections of DNA typically used to identify genetic variation across populations. Scientists embed a clients DNA into a small silicon chip containing reference DNA from both healthy and ill individuals. If the client’s genetic info matches up with the DNA common among people afflicted by certain diseases, the scientist can give a person an idea of how likely it is that they will contract those diseases. The results remain largely inconclusive. If you share a strand of diabetes’s related DNA with a person who actually has it, the chances of them getting it are certainly elevated, but not a hundred percent. The same would be true for this person’s child, if the child and parent shared the same strand, the child is at an elevated risk as well.
