Involvement in diseasei

Facial paresis, hereditary congenital, 3 (HCFP3)1 Publication

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionA form of facial paresis, a disease characterized by isolated dysfunction of the facial nerve (CN VII). HCFP3 patients are affected by bilateral facial palsy, facial muscle weakness of muscles innervated by CN VII, hearing loss, and strabismus.
