Hereditary deafness, also known as Early-onset Adult Deafness (EAOD), is a hereditary hearing disorder that occurs in the Beauceron and is associated with a mutation in the CDH23 gene. This gene plays a key role in the functioning of the hair cells in the inner ear, which are necessary for processing sound.
The condition is inherited in an autosomal recessive manner and usually causes bilateral deafness at a young age. In addition to bilateral deafness, some dogs may exhibit balance problems, startle responses or behavioural changes.
