Non-syndromic hearing loss is a hereditary condition that results in profound hearing loss and deafness.
LOXHD1
Autosomal recessive
Clinical signs related to hearing impairment typically present in puppies. These may include a failure to respond to sounds, difficulty to rouse from sleep, or excessive barking.
A veterinarian will conduct a thorough exam, including a review of health history and any clinical signs. Laboratory tests and/or a neurological exam may be conducted. Genetic testing is necessary to determine if there is an underlying genetic cause, which can assist veterinarians with diagnosis and help breeders identify affected and carrier dogs.
