Tuberous sclerosis is caused by mutations of tumor suppressor genes, including hamartin (tsc1) on chromosome 9, and tuberin (tsc2) on chromosome 16. It usually occurs sporadically although it occasionally is found in families. Can cause glaucoma, seizures, hemiparesis, and mental retardation.
Weber syndrome, clinical case , Ipsilateral 3rd
The disease is typically inherited in an autosomal dominant fashion, and the most common cmt1a subtype is caused by a duplication of pmp22.
• caused by somatic acivating mutation in gnaq gene.

On physical exam, a port wine stain is appreciated, affecting the ophthalmic and maxillary division of the trigeminal nerve on the left side of the face.
Sturge weber syndrome is a neurocutaneous condition characterized by facial port wine stain, seizures and other neurologic complications associated with angiomata of the leptomeninges, and glaucoma.
Males and females are equally affected. Specifically, patients demonstrate leptomeningeal angiomas, along with arteriovenous malformations (avms). Sturge weber syndrome is a sporadic disorder caused by activating mutations mutations in the gnaq gene.
