" /> Sturge-weber syndrome - CISMeF





Preferred Label : Sturge-weber syndrome;

Symbol : SWS;

CISMeF acronym : SWS;

Type : Phenotype, molecular basis known;

Description : Sturge-Weber syndrome is characterized by an intracranial vascular anomaly, leptomeningeal angiomatosis, most often involving the occipital and posterior parietal lobes. The most common symptoms and signs are facial cutaneous vascular malformations (port-wine stains), seizures, and glaucoma. Stasis results in ischemia underlying the leptomeningeal angiomatosis, leading to calcification and laminar cortical necrosis. The clinical course is highly variable and some children experience intractable seizures, mental retardation, and recurrent stroke-like episodes (review by Thomas-Sohl et al., 2004).;

Inheritance : Somatic mosaicism;

Molecular basis : Caused by somatic mosaic mutation in the guanine nucleotide-binding protein q gene (GNAQ, 600998.0001);

Prefixed ID : #185300;
