 Saliva can detect gifted genes? CCTV: never believe in the life of spoiler


It is the pursuit of every parent to look forward to their children and their daughters. If someone tells you that with a few milliliters of saliva and a few hundred yuan of testing fee, you can know whether your child is suitable for painting or dancing, and will become an artist or an athlete in the future. Do you think its reliable for such a life spoiler?

Search gene detection of childrens talent on the e-commerce platform, you can see several pages of related products. Prices range from a few hundred to a few thousand, and the content of testing varies from dance to art, from sports to music. The test method is also very simple. Just scrape a swab on the inner wall of the mouth and send the sample back to the test center. After a week and a month, you can receive the talent gene test report. The reporter contacted one of the gene testing companies and asked which talents could be tested.

Business manager of a gene testing company in Chongqing: what we are selling now is 498, childrens talent. Its equal to childrens talent, everything.

The managers everything is not empty talk. At present, in addition to sports, painting, dance, music and other common talents, there are even leadership, happiness, stress resistance, learning ability and even success and other very abstract ability assessments. Plus let every little genius win at the starting line, choose the wrong interest, maybe let the genius become mediocre, such advertising words and sentences poke at the heart of parents, many products have hundreds of purchase records and comments. And such talent genetic testing is reliable or not, the head of another testing company vowed: very reliable.

Business manager of a gene testing company in Shenzhen: if you find out that you have talent genes, it means that you are definitely right to develop in this direction.

Breakthrough in natural gene detection technology or market chaos?

The so-called talent, such as leadership and success, is very vague or even different from each other. How can genetic testing predict talent?

In the report of talent genetic testing, we found some answers. It turns out that every so-called talent corresponds to one or several gene points. According to the rough statistics, there are more than 120 talent gene loci determined in the test reports provided by businesses, but the number of talents judged based on them has extended hundreds of different opinions.

Business manager of a gene testing company in Chongqing: his gene location is like this. For example, music is two gene locations and sports is one gene location. One or two or three points per talent. Its almost the same. At present, I tell you that all agencies adopt the same points, but the report template is different.

Two or three gene points cant lead a life

With two or three gene loci, can a persons ability in dance, music, even leadership and success be determined? With this question, the reporter consulted the experts of precise genome of the Chinese Academy of Sciences.

Zeng Changqing, director of the Key Laboratory of precision genomics medicine, Chinese Academy of Sciences: there are many kinds of talents, some of which are related to thinking, some of which are memory, some of which are athletic ability, and some of them are long-distance and short-distance running. This mechanism is also different. The so-called talent gene, which itself refers to a particularly complex gene. Our name is complex character. What is complex character? For example, there are many genes controlling your height. We know that there are some loci that will affect your height, but its contribution rate may be very low, which is millimeter level. You can predict whether this child will grow up to be like Yao Ming in the future. I think this is not so mature.

Experts believe that these completely different talents involve a large number of different genes and molecular mechanisms. To make this clear, we need to study many individuals with the same talent at the same time. At present, there is no such big data. Therefore, using two or three points to judge the grand proposition of talent is no different from electronic fortune telling. In order to propagandize, the business enterprise linked a gene with the future of the child, and made up the weak correlation with the brain as the decisive factor, so as to stimulate the parents consumption. In view of various exaggerated publicity and emerging new concepts of talent in the current market, experts suggest that we should not superstitious about the results of genetic testing of childrens talent, but also pay attention to their own interests and the role of nurture.

Zeng Changqing, director of the Key Laboratory of precision genomics medicine, Chinese Academy of Sciences: the current scientific progress can only be said that our gene detection is focused on the research of diseases, and we have not focused on the research of talents. Especially many parents want their children to be smart. Just now I said talent, but a persons ability is the combination of talent and your day after tomorrow, right? So that day after tomorrow is particularly important.

Gene testing is not a verdict on disease

Its not reliable to predict the talent that we will treasure and tap in our lifetime by only two or three gene loci. At the same time, the reporter also found that the detection of many gifted genes has been put into more mature gene detection projects such as ancestral analysis and disease risk screening for sale. So on the market about genetic disease screening, disease risk gene detection project, whether has the reference value?

(function() {(window. Slotbydup = window. Slotbydup| []). Push ({ID: u5811557, container: ssp_, async: true});}) ()); Zeng Changqing, director of the Key Laboratory of precision genomics medicine, Chinese Academy of Sciences: there are many products, especially products and tests related to risk. For example, if I analyze your ancestry, or if you want to see my own disease risk, you need to find the right one Regulatory. The results of these analyses are still well founded. But I dont recommend talent. Experts remind that when we get a genetic test report, although there is some theoretical support for the part about the risk of disease, for individuals, we should also treat this result rationally. Use the report as a reminder, not as a verdict. Zeng Changqing, director of the Key Laboratory of precision genomics medicine, Chinese Academy of Sciences: do you have any character or disease? It must be the result of the interaction of genetics, environment and postnatal. If you have a genetic risk, you dont have to get it. If the risk is not so high, it doesnt mean theres nothing left. It must be a comprehensive function, but if you have a high risk, you are really easy to be triggered, so you should pay more attention. Source: CCTV news client editor: Liu Yuxin

Zeng Changqing, director of the Key Laboratory of precision genomics medicine, Chinese Academy of Sciences: there are many products, especially risk products and tests. For example, if I analyze your ancestral source, or if you want to see my own disease risk, you need to find a regular one. The results of these analyses are still well founded. But I dont recommend talent.

Experts remind that when we get a genetic test report, although there is some theoretical support for the part about the risk of disease, for individuals, we should also treat this result rationally. Use the report as a reminder, not as a verdict.
