Genomics research shows that the human genome contains 20 to 25000 genes, but so far, using gene detection technology, only more than a thousand disease genes can be found, and all of them are single gene diseases. However, polygenic diseases in humans are still a blind spot for technical testing. In this regard, the existing genetic test results all use high, medium, low or a certain percentage range to indicate the risk probability of an individual suffering from a certain disease, which simply cannot reach the so-called 100% accuracy. In addition, even if the genetic test results are normal, the possibility of getting sick cannot be ruled out.
