Moebius Syndrome is suspected to be a random genetic trait that creates a neurological disorder rooted in a wide range of cranial nerves. The disorder can cause facial immobility, so that one is not able to make facial expressions like smiling or frowning. The muscle weakness- along with a cleft palate- can also lead to problems feeding and speaking. A person with Moebius Syndrome might also experience respiratory problems, visual impairments, sensory integration dysfunction, and more.
The symptoms of this disorder are apparent at birth. Infants are typically born with a small chin and mouth and an unusually shaped tongue. Dental abnormalities such as missing or misaligned teeth are also common. Other features include bone abnormalities in the hands and feet, weak muscle tone, and hearing loss. Affected children often experience a delayed development of motor skills and one third of them fall somewhere on the Autism Spectrum. Though it might slightly increase the risk of an intellectual disability, people with Moebius Syndrome are typically of normal intelligence.
