    Writing in the British Medical Journal, British genetic experts warned that genetic testing, which is currently available directly to consumers, could be misleading: when such testresults suggest a "health risk" it does not mean that consumers are bound to develop a disease, and "reassuring" good results are not credible. In an article
    researchers at the University of Southampton and the University of Exeter, the university of Southampton and the University of Exeter, in the UK, point out that some of the publicity about consumer-grade genetic testing leads to the belief that such testing can give people an idea of their ancestors, ancestry, associated disease risk, and personality or motor ability, but in practice it is not so simple to interpret genetic information.
    researchers point out in the article that most genetic testing directly to consumers does not sequence a person's entire gene or genome, but focuses only on specific genetic mutations, which can lead to false positive results.
    even sequencing the entire genome, the genetic mutations found often have no clinical significance. In fact,
    article says, some genes people carry may increase their risk of disease, but there are others that protect them from disease.
    lead author, Anique Lucen, a professor of medical genetics at the University of Southampton, explains that some people go to the hospital with genetic tests showing a higher risk of developing diseases such as cancer to reduce the risk of cancer, and that detailed technical tests at the hospital have found that they do not need surgery at all.
    others are worried about their cancer risk even after being persuaded to cancel the surgery.
    on the other hand, because most consumer-grade genetic tests screen only a small number of genetic mutations and are therefore incomplete, the "reassuring" results it shows are not credible.
    had previously had a woman with a family history of breast and ovarian cancer who failed to detect BRCA gene mutations associated with both cancers through consumer-grade genetic testing, but other cancer-causing gene mutations were detected through other tests.
    therefore, the researchers suggest that people with a family history should go to a professional hospital rather than go to a professional hospital instead of using this consumer-grade genetic test entirely to understand and check for their risk of disease.
    gene testing market is hot, where are the relevant opportunities? At present, the market for genetic testing in children is getting hotter and hotter.
    have been the subject of genetic testing, from talent to IQ, drug sensitivity to artistic inclination.
    , what is the current state of the market? Genetic testing, a word that sounds high, has gradually entered our lives in recent years.
    in addition to the traditional hospital sedituated the disease-specific genetic testing, businesses also seize the parents concerned about the child's growth mentality, targeted to launch a variety of famous children's genetic testing.
    "Don't let your child lose on the starting line," "genetic testing, precision education," "let your child in the long and short, in the best areas to play the maximum advantage" these are many children's genetic testing products launched advertising.
    many parents want to know something about children's genetic testing.
    "genes" are the blueprints for every species, including humans, from the muscles we see to everyone with different personalities.
    because of the importance of genes to humans, genetic testing began to leave the medical field, into the consumer market, and rapid growth.
    2018 (test volume) 2017 year-on-year, we are growing at about 30%, that is mainly due to the opening of the two-child policy, that the first quarter of 2019 compared to 2018 (test volume) to compare, the growth rate is also about 20 to 30%.
    in the eyes of the industry, the current children's genetic testing is the first is too many items, quality is not the same;
    on the other hand, many institutions for the genetic test results of the professional interpretation of poor, people can not distinguish what is trustworthy genetic testing project, and some reports are too simple, people feel that its entertainment is greater than the professional gene diagnosis, while consumers lack of knowledge of genetic testing, but also make the problem more serious.
    in addition to a wide range of names, the query found that the price is also a huge gap, from less than one hundred yuan, to up to 56,000 yuan, so that consumers are difficult to choose.
    also have institutions say that because of advances in technology, the price of genetic testing is ever-changing, so the price of moisture is difficult to identify.
    about genetic testing: Genes (Mendelian factor) are DNA or RNA sequences that carry genetic information (i.e., genes are DNA or RNA fragments with genetic effects), also known as genetic factors, which are the basic genetic units that control traits.
    genes control the behavior of biological individuals by directing the synthesis of proteins to express the genetic information they carry.
    genes are the basic unit of genetics, carrying DNA or RNA sequences with genetic information, and by copying, passing genetic information to the next generation, guiding the synthesis of proteins to express the genetic information they carry, thereby controlling the expression of the characteristics of biological individuals.
    genetic testing is a method of detecting DNA by blood, other body fluids, or cells, taking the peripheral venous blood or other tissue cells of the person being tested, amplifying their genetic information, testing the DNA molecular information in the tested person's cell through a specific device, analyzing the gene type and gene defects it contains and whether their expression function is normal, so that people can understand their genetic information, identify the cause or predict the risk of a certain disease in the body.
    genetic testing is the dna testing technology through blood, other body fluids or cells, is to take the tested person shed the oral mucosa cells or other tissue cells, expand their genetic information, through a specific device to test the DNA molecular information in the tested person's cells, predict the risk of disease in the body, analyze the various genetic conditions it contains, so that people can understand their own genetic information, so that people can improve their living environment and living habits, avoid or delay the occurrence of disease.
    genetic testing can diagnose diseases or can be used to predict disease risk.
    disease diagnosis is a genetic test to detect mutated genes that cause genetic diseases.
    the most widely used genetic testing at present is the detection of genetic diseases in newborns, the diagnosis of genetic diseases and the diagnosis of certain common diseases.
