Genetic factors are one of the important causes of hearing loss. In order to determine the genetic mode and pathogenic gene of non-syndromic hearing loss family, this study used high-throughput gene sequencing technology to screen and analyze the family.Randomly selected blood samples from three generations of the family (10 people in total) were subjected to exon gene sequencing to analyze the genetic mode of the family, and bioinformatics tools were used to identify possible pathogenic genes. In the screening process, quality control standards and filtering methods were used to screen out mutation sites that meet the requirements.The screened mutations were analyzed by bioinformatics, and the database was compared to determine their pathogenic effect on hearing loss. Finally, it was found that the mutation of 精品文档---下载后可任意编辑gene ACCG1 is closely related to the occurrence of non-syndromic hearing loss.This study provides new ideas and methods for exploring the pathogenic genes of non-syndromic hearing loss.Keywords: non-syndromic hearing loss, genetic mode, gene screening, mutation analysis, bioinformatics.
