1. In our cohort, 15 common hearing-loss mutations
with a high carrier frequency (15.9%) were screened; GJB2
c.109G>A was the most common mutation (10.9%).
2. For patients with hearing loss who were negative for the 15 common mutations, our hearing-loss target capture panel combined with a massively parallel sequencing approach increased detection of pathogenic mutations or likely pathogenic variants by 21%.
