Monogenic hearing loss

Gene: EYA1

PMID: 23840632 - Song et al 2013 - analysed EYA1, SIX1 and SIX5 in 7 families (10 patients) - all with typical BOR/BO syndrome, except for one patient who exhibited only mixed type of hearing loss and inner ear anomalies. One missense and three splice site mutations were identified in EYA1, while no mutations were found in either SIX1 or SIX5 gene
