Brown–Vialetto–Van Laere Syndrome

The Brown–Vialetto–Van Laere syndrome (BVVL), sometimes better known as Brown's Syndrome, is an exceptionally rare neurological disorder of unknown cause, characterized primarily by deafness and paralysis of the muscles of the face, neck, shoulders and limbs. The neurological manifestations develop insidiously: they usually begin with sensorineural deafness, progress inexorably to paralysis, and often culminate in respiratory failure. The syndrome affects children, adolescents, and younger adults; the age at onset of symptoms in the reported cases has ranged from infancy to the third decade of life. The prognosis is poor—most patients diagnosed with the syndrome die within 10 years. There is no cure.

The gene defective in at least some patients with BVVL has been identified by a team of British researchers: C20orf54. This gene is thought to be involved in transport of riboflavin It has been proposed that Fazio–Londe disease and Brown-VialettoVan–Laere syndrome are a phenotypically associated condition.

Famous quotes containing the word syndrome:

    [T]he syndrome known as life is too diffuse to admit of palliation. For every symptom that is eased, another is made worse. The horse leech’s daughter is a closed system. Her quantum of wantum cannot vary.
    Samuel Beckett (1906–1989)
