Sturge–Weber syndrome
neurological and skin disorder associated with port-wine stains of the face, glaucoma, seizures, intellectual disability, and cerebral malformations
Sturge–Weber syndrome, sometimes referred to as encephalotrigeminal angiomatosis, is a rare type of phakomatosis, a congenital disorder that affects the central nervous system, skin, and eyes. It is often associated with port-wine stains of the face. Clinical manifestations include glaucoma, choroidal lesions, seizures, intellectual disability, and benign tumors of the blood vessels of the leptomeninges.
Sturge–Weber originates from embryonic development, resulting from errors in mesodermal and ectodermal development. Unlike other phakomatoses, Sturge–Weber occurs sporadically (i.e., does not have a hereditary cause). It is caused by a mosaic, somatic activating mutation occurring in the GNAQ gene.
Diagnosis is usually done through imaging; findings may include tram track calcifications in the cerebral cortex on a CT scan, angiomatosis of the pia mater, and hemicerebral atrophy. Managing Sturge–Weber focuses on treating the symptoms as they appear. Around 1 in 50,000 newborns are affected by the disease. It was originally described in 1879 by William Allen Sturge.
Begin with the source’s own compact description: “Sturge–Weber syndrome” is neurological and skin disorder associated with port-wine stains of the face, glaucoma, seizures, intellectual disability, and cerebral malformations. The dossier treats that line as a proposition to test through Sturge, Weber and syndrome, not as a finished interpretation.
Why this record matters
The phrase “neurological and skin disorder associated with port-wine stains of the face, glaucoma, seizures, intellectual disability, and cerebral malformations” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Feb 13, 2026. The linked authority identifier is Q1886238. The Library of Congress control number is sh85129350. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1879.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
