Deafness, bilateral, and vestibular dysfunction, MYO7A-related(DINGS2)
MYO7A-related deafness and vestibular dysfunction · MYO7A-associated bilateral deafness · MYO7A-Taubheit und vestibuläre Dysfunktion · Congenital sensorineural deafness and vestibular dysfunction MYO7A · Deafness with Vestibular Dysfunction 2 · Bilateral Deafness with Vestibular Dysfunction (DINGS2)
What it is
This inherited inner ear disorder, also known as DINGS2, is caused by a genetic mutation in the MYO7A gene. The mutation disrupts the sensory hair cells in the inner ear that are responsible for transmitting sound and maintaining balance. Consequently, affected dogs suffer from complete hearing loss in both ears and a poorly functioning vestibular system.
How it presents
Symptoms usually appear within the first few weeks of life as puppies start moving around. Owners will typically notice complete deafness, a distinct head tilt, clumsy or uncoordinated walking, and general disorientation.
Treatment
There is no cure for this lifelong condition, meaning affected dogs require permanent lifestyle adjustments and a secure environment. While there is no medical treatment to restore hearing or balance, supportive care and safety measures typically cost between 300 and 1500 EUR.
