Gene sequencing is also a well-known non-invasive prenatal genetic test for Down syndrome screening. Only 5 ml of pregnant women's blood is needed. By detecting the concentrations of AFP and β-hCG in the blood, the risk of Down syndrome in the fetus can be calculated. [5]
Recently, H7N9, which has attracted public attention, is a new recombinant avian influenza virus discovered by Chinese scientists through gene sequencing and other technical means. [5]
In recent years, gene sequencing has moved from laboratory to clinic, and even gradually become a hot topic in the global medical field. One of the most important reasons is the "celebrity effect". Steve Jobs, the founder of Apple, and Angelina Jolie, the movie star, both used gene sequencing to resist the invasion of cancer, and Julie also had her breasts removed preventively. Although Jobs still died of cancer, the whole gene sequencing he received before his death has become a high-end physical examination service sought after by the rich in many countries.
