Abstract: Abstract: Whole exome sequencing (WES)， which focuses on the protein coding region of the whole genome， aims to identify diseases related coding variants through sequencing the enriched exons of the genome. In recent years， WES is increasingly applied in several research fields， such as to identify novel low frequency variants， find causal genes of single gene inheritance diseases， in research of complex diseases like cancer. It has become one of the most important strategies in identifying diseases associated genes. Here we reviewed the basic technical principal of WES and its application in research of human diseases related genes.
Key words: exome sequencing; genetic disease; predisposing genes
