  Objective: To establish the diagnostic platform of hereditary hearing impairment by combining targeted genes capture with high-throughput sequencing technology, and verify the efficiency of this method, laying the methodological foundation of further analysis to cover a variety of genetic hereditary hearing impairment samples to determine the proportion of genetic causes of hearing loss preliminary, as well as to analyze the incidence of each gene in various hearing loss population.Methods: In this study, mutation screening of 307 nuclear genes and mitochondrial genome responsible for human or mouse hearing impairment were performed in the eighty three patients with 39 known mutations to verify the validity of our methods firstly.

通过对现有文献的总结,本研究共收集了202个(包含46个miRNA)地中海贫血调控相关的基因,进行了地贫病人外周血DNA的目标区域捕获测序,并完成了842例病人在以上捕获区域内的突变分析.为了系统地分析这些样本在5端非编码区(5UTR)中可影响基因沉默或开放的突变,本研究利用公共数据库Refgene和人类基因组序列(hg19),应用BioPerl构建了本地的人类基因组转录本5UTR坐标及对应序列文
