Genetic mutations in nonsyndromic deafness patients of Chinese minority and han ethnicities in Yunnan China

摘要

BackgroundEach year in China, 30,000 babies are born with congenital hearing impairment. However, the molecular etiology of hearing impairment in the Yunnan Province population where more than 52 minorities live has not been thoroughly investigated. To provide appropriate genetic testing and counseling to these families, we investigated the molecular etiology of nonsyndromic deafness in this population.
