I. Gene sequencing is the basis of precision medicine industry development, as well as the fledged field of commercialization application in precision medicine industry.

Genetic analyzer is a key point in gene sequencing industry chain. The upstream of gene sequencing consists of genetic analyzer, reagents and consumables, while the middle and downstream include gene sequencing services and bioinformatics analysis, being oriented to hospitals, pharmaceuticals companies, scientific research institutions and consumers. In gene sequencing industry chain, genetic analyzer is a key point as well as the starting point, supplying the most basic sequencing support to middle and downstream sequencing services.

The core of genetic analyzer is sequencing technology. Since the first genetic analyzer came into being in 1985, the ever-accelerated development of gene sequencing technology and the unceasing reduction of cost have enabled the gene sequencing to head from scientific research stage for commercial application. So far gene sequencing technology has developed the third generation of sequencing technology while the second generation of sequencing technology is under extensive commercial application.

  

II. Gene sequencing services remain comprehensively competitive, facing a new pattern of industrial integration for reconstruction and development.

The market competition is rather fierce with numerous participants for sequencing services. There are thousands of manufacturers offering sequencing services around the world and over 200 ones in China (over 100 only in Beijing, Shanghai and Guangzhou). Their gene sequencing services include non-invasive prenatal diagnosis, tumor diagnosis and treatment, genetic diagnosis and assisted reproductive technology. As a hi-tech field, gene sequencing industries are mainly distributed in first- or second-tier cities in mid-eastern China like Beijing, Shanghai, Shenzhen, Zhejiang, Guangzhou, Wuhan and Nanjing where talents are intensively gathered.

III. Big data analysis plays an important role in future gene sequencing and gene database will serve as the strategy core for sequencing services.
