The invention discloses a kit and a method for detecting 50 tumor-relevant
hotspot mutation genes. According to the method, a capture method of 207
hotspot mutation regions of 50 relevant genes (including oncogenes and
cancer suppressor genes) and a preparation method of a liquid-phase hybridization
library used in capturing are researched aiming at
oncology. The method particularly comprises the steps of selecting sequence information of 207
hotspot mutation regions, designing a PCR primer, preparing a
biotin labeled liquid-phase hybridization
library by virtue of a
PCR method, hybridizing the
biotin labeled liquid-phase hybridization
library with a constructed target
genome DNA library, and carrying out high-
throughput sequencing and
bioinformatics analysis on captured fragments, so as to obtain the
mutation condition of
nucleic acid sequence sites of a sample. By virtue of the method provided by the invention, high-quality
sequencing data can be obtained, the relatively high capturing efficiency and the relatively good uniform capturing of the target sites can be realized, the disadvantages of low efficiency, poor uniformity and the like of
solid phase hybridization are solved, and the sequencing cost is greatly lowered.
