Surdité congénitale (EOAD) - Rottweiler

Hereditary deafness is widely spread among multiple dog breeds with differing age of onset, diverse clinical symptoms and various genetic causes. Hereditary hearing loss described in Rottweilers is identified as the LOXHD1 variant. This variant is caused by a mutation in the gene responsible for the normal function of the mechanosensory hair cells in the cochlea (part of the inner ear containing the sensory organ for hearing), resulting in the deterioration of the inner ear hairs and deafness. This variant is specific for the Rottweiler breed, but it can also be found in mixed-breed dogs with Rottweiler ancestry. The hearing loss usually becomes evident at birth or in the first few weeks of life, progressing into total bilateral deafness. The affected dogs show no other clinical symptoms.
