This study also supports the notion that the mutations in GJB2, SLC26A4, and the mitochondrial gene are the major genetic causes of nonsyndromic SNHL in China, and account for approximately 53.85% (63/117), 20.51% (24/117), and 13.68% (16/117) of these cases, respectively. This evidence concerns the gene SLC26A4 and sensorineural hearing loss disorder.
