Moebius Syndrome
- results from the underdevelopment of the VI and VII cranial nerves.
- The VI cranial nerve controls lateral eye movement, and the VII cranial nerve controls facial expression.
- rare neurological disorder
- characterized by weakness or paralysis (palsy) of multiple cranial nerves
- most often affects the 6th (abducens) and 7th (facial) nerves.
- The disorder is congenital
- Other abnormalities include underdevelopment of the pectoral muscles and defects of the limbs.
- can include bone abnormalities in the hands and feet, weak muscle tone (hypotonia), and hearing loss.
- Â delayed development of motor skills (such as crawling and walking), most eventually acquire these skills.
- may also be associated with a somewhat increased risk of intellectual disability; however, most affected individuals have normal intelligence.
