Mutation analysis of common deafness genes among 1201 patients with non‐syndromic hearing loss in Shanxi Province

摘要

BackgroundHearing impairment is one of most frequent birth defects, which affects nearly 1 in every 1,000 live births. However, the molecular etiology of non‐syndromic deafness in China is not well studied. Here, we have investigated the presence of mutations in three genes commonly mutated in non‐syndromic deafness patients in Shanxi Province, which has the highest frequency of birth defects in China.
