[Research progress and clinical application of the third- generation sequencing techniques].

The Sanger sequencing techniques, also known as the first-generation sequencing techniques and the gold standard of sequencing, have promoted the completion of "working draft" of the human genome, but the disadvantages of low throughput and high cost limit its large-scale application. The second-generation sequencing techniques, also known as the next-generation sequencing techniques, have widely used in basic research and clinical application because of its high throughput and low cost, but the short reads has always been an unavoidable shortcoming. Then, the emergence of the third-generation sequencing techniques, with the long reads, provides new technology selection for the analysis of complex repetitive regions on genome sequences and the assembly of high-quality genomes. In recent years, the third-generation sequencing techniques have been further developed, and have gradually demonstrated the clinical application value. This article reviewed the research progress and clinical application of the third-generation sequencing techniques.
