Sensorineural hearing loss and mild cardiac phenotype caused by an EYA4 mutation

EYA4 is a member of the vertebrate eya gene family of transcriptional activators and plays several roles in both embryonic and inner ear development. The majority of EYA4 gene mutations are associated with autosomal dominant non-syndromic hearing loss (DFNA10). In addition, some mutations in this gene cause autosomal dominant syndromic hearing loss with dilated cardiomyopathy. EYA4 is a rare cause of sensorineural hearing loss, and only a limited number of papers regarding mutations in this gene have been published. Thus, detailed clinical features remain unclear
