ABSTRACT
OBJECTIVE@#Mutations in the GJB2 are the most common cause of nonsyndromic autosomal recessive sensorineural hearing loss. A few mutations in GJB2 have also been reported to cause dominant nonsyndromic or syndromic hearing loss. This study analysised the GJB2 dominant mutation in Chinese deafness.@*METHOD@#1641 patients as GJB2-related hearing loss were enrolled, summarized the type of dominant mutaion, analyzed the hearing level and other systerm lesion.@*RESULT@#Nine probands with severe-profound hearing loss were diagnosed as GJB2 domiant mutation (R75W,G130V, R143Q,p. R184Q). And one patient with R75W mutation was diagosed as hearing loss and palmoplantar keratoderma.@*CONCLUSION@#GJB2 dominant mutation can cause severe-to-profound bilateral sensorineural hearing impairment and not common with syndromic hearing loss in Chinese deafness.
