Sturge-Weber syndrome is a rare disorder that is present at birth. Affected individuals have a large port-wine stain birthmark on their face, which is caused by blood vessel abnormalities. People with Sturge-Weber syndrome also develop blood vessel abnormalities in the brain called leptomeningeal angiomas. Other features of this syndrome include glaucoma, seizures, muscle weakness, paralysis, developmental delay, and intellectual disability. Sturge-Weber syndrome is caused by a mutation in the GNAQ gene. The gene mutation is not inherited, but occurs by chance in cells of the developing embryo.[1]
