Summaries for Brown-Vialetto-Van Laere Syndrome 1

OMIM : 58 Brown-Vialetto-Van Laere syndrome is a rare autosomal recessive neurologic disorder characterized by sensorineural hearing loss and a variety of cranial nerve palsies, usually involving the motor components of the seventh and ninth to twelfth (more rarely the third, fifth, and sixth) cranial nerves. Spinal motor nerves and, less commonly, upper motor neurons are sometimes affected, giving a picture resembling amyotrophic lateral sclerosis (ALS; 105400). The onset of the disease is usually in the second decade, but earlier and later onset have been reported. Hearing loss tends to precede the onset of neurologic signs, mostly progressive muscle weakness causing respiratory compromise. However, patients with very early onset may present with bulbar palsy and may not develop hearing loss until later. The symptoms, severity, and disease duration are variable (summary by Green et al., 2010). (211530)

MalaCards based summary : Brown-Vialetto-Van Laere Syndrome 1, also known as pontobulbar palsy with deafness, is related to riboflavin transporter deficiency neuronopathy and riboflavin transporter deficiency, and has symptoms including dyspnea, clumsiness and stridor. An important gene associated with Brown-Vialetto-Van Laere Syndrome 1 is SLC52A3 (Solute Carrier Family 52 Member 3), and among its related pathways/superpathways is Metabolism of water-soluble vitamins and cofactors. Affiliated tissues include tongue and cerebellum, and related phenotypes are ataxia and ptosis

UniProtKB/Swiss-Prot : 76 Brown-Vialetto-Van Laere syndrome 1: A rare neurologic disorder characterized by sensorineural hearing loss and a variety of cranial nerve palsies, which develop over a relatively short period of time in a previously healthy individual. Sensorineural hearing loss may precede the neurological signs. The course is invariably progressive, but the rate of decline is variable within and between families. With disease evolution, long tract signs, lower motor neuron signs, cerebellar ataxia and lower cranial nerve (III-VI) palsies develop, giving rise to a complex picture resembling amyotrophic lateral sclerosis. Diaphragmatic weakness and respiratory compromise are some of the most distressing features, leading to recurrent chest infections and respiratory failure, which are often the cause of patients' demise.
