Recently, there have been projects on the market to detect children's natural genes through saliva. The “natural talents†mentioned in this paper involve curiosity, memory, stress resistance, ability to learn lessons, mathematical calculation ability, reading ability, etc. The fee range is from several hundred yuan to It costs about ten thousand yuan. Many children's parents are convinced of this, thinking that with high-tech means can get a guide to train a child's talent. So, can a little saliva detect the child's talent? How to identify which consumer-grade genetic tests in the market are reliable? With questions, the March 20th Science and Technology Daily reporter interviewed famous Chinese and foreign experts. Consumer-grade genetic testing is gradually gaining public view “Gene detection is mainly about detecting the risk of a disease you may be suffering from, ranging from low risk, general risk to high risk, allowing people to self-examine the possibility of a disease. But it is important to emphasize that even if you are at a height At the end of the risk, it does not mean that 100% of patients will suffer from certain diseases, but the risk value is relatively high." Aihua, professor of nutrition research at the Institute of Sports Medicine, Peking University Third Hospital, told the Science and Technology Daily. In general, unlike professional-level genetic testing related to research and medicine, consumer-grade genetic testing is directly available to the general public, and the price is not very high. Through a little saliva sample of the user, health risks, nutrient metabolism, food sensitivity and exercise capacity are detected. In response to the individualized needs of the public, specialized institutions have also developed a variety of services, such as adult nutrition, obesity, child nutrition campaigns and other individual tests, some up to 58 sub-items. At present, professional consumer-grade genetic testing is based on the latest scientific results at home and abroad. For example, the internationally renowned journal "Dermatology Research Journal" has published an article stating that the age of hair whitening is mainly determined by genetic factors. And which gene has a certain correlation with the production of crow's feet or obesity. Aihua said, "Consumer-level genetic testing is very necessary to promote, providing a scientific basis for consumers to accurately manage their own health." Not every so-called talent can be measured "To a certain extent, genetic testing can test someone's talent in sports, whether it is endurance or explosive. But it does not mean that every so-called talent we understand can be measured, such as people. Social ability, memory and stress resistance, many of these behaviors are affected by acquired environment such as society, family and other factors," said Dr. Stewart Grice, a member of the Oxford University of Disease Genomics. In 2016, an article published in China's core journal "Sports Science and Technology" said that the results of a study on the Chinese Han nationality's excellent middle and long distance swimmers showed that a gene in the genome called the augmented motor protein 3 (ACTN3) RR type locus. The frequency is significantly higher than other genotypes and can be used as a molecular marker for the selection of outstanding athletes in the project. In 2017, researchers from the European University of Madrid in Spain published an article in the British Journal of Sports Medicine, which also mentioned the ACTN3 gene, which is related to the football player community. "It is worth noting that there is currently no way to detect a lot of information regulating DNA, and they play an important role in the human body, so genetic testing can not be aware of all human mysteries." Aihua stressed. In order to identify the reliable genetic testing According to incomplete statistics, there are more than 200 consumer-level genetic testing companies in China. It is predicted that 50 million people in China will have their own genomic data in 2022. Grice suggested that there are three points to be noted: professionalism, for example, whether the research is cooperating with many universities; openness, regardless of research or research, must be open to customers, and accept questions from the public at any time; continuity Now, genetic testing is an emerging industry. From a scientific point of view, there must be products that are constantly updated as research progresses. Aihua said: "In addition to testing, genetic testing is also an important method of identification. For example, the coactin 3 gene is often used to detect sports talent. The R-type variation of this gene may cause a body to form a kind of Proteins present in fast muscle fibers provide explosive power to the body, while X-type mutations inhibit the production of this protein. Therefore, the report should indicate which gene corresponds to the relevant result."

So, how do consumers identify the genetic testing programs that are reliable in the market?
