Trait
Bell's palsy
Clinical name: Facial palsy
Facial nerve palsy is a dysfunction of cranial nerve VII (the facial nerve) that results in inability to control facial muscles on the affected side with weakness of the muscles of facial expression and eye closure. This can either be present in unilateral or bilateral form.

Changes in these genes cause rare conditions in which Bell's palsy is seen. Most people with this trait have none of those conditions, and a gene on this list says nothing about anyone's own genome.
