Today, scientists are able to use your genome to predict your chances of getting heart disease or breast cancer, and even your IQ.
Genetic fortune or DNA-based predictions could actually become the next big thing in public although it will increase the risks of genetic discrimination. The science making these report possible has arrived suddenly, all thanks to huge genetic studies which has been reported to involve more than a million people.
Apparently, most common diseases and behaviors or traits, which includes intelligence, are as a esult of not one or a few genes but many genes acting in concert.
As reported by Antonio Regalado, new DNA tests offer probabilities, not diagnoses and would be of great benefit to medicine. For example, if a good number of women with high risk for breast cancer got more mammograms and those at low risk got fewer, the exams might catch more real cancers and set off less false alarms.
Also, Pharmaceutical companies can use the scores in clinical trials as a preventive drug for illnesses like Alzheimer’s or heart disease. The only issue is that predictions are far from perfect. Who wants to know they might develop Alzheimer’s? Or what if someone with a low risk score for cancer puts off being screened, and then develops cancer at the end?
The Polygenic scores are also a bit controversial because they can predict any trait, and not only diseases, that is to say, they can forecast about 10 percent of a person’s performance on IQ tests. As the scores improve, it is likely that DNA IQ predictions will become routinely available.
The behavioral geneticist, Eric Turk Heimer, stated that the chance that genetic data will be used for both good and bad is what makes the new technology both simultaneously exciting and alarming.
