Fazio-Londe syndrome (Q85582): Difference between revisions

Fazio-Londe syndrome is an inherited disorder characterised by childhood onset of bulbar, facial and respiratory weakness with limb hyperreflexia. Fazio-Londe syndrome shares a similar clinical phenotype with Brown-Vialetto-Van Leare syndrome, except there is no hearing loss. Fazio-Londe syndrome is recessively inherited, a result of homozygous or compound heterozygous mutations in the SLC52A3 gene. Patients may respond to therapy with riboflavin. NEW: Progressive bulbar paralysis of childhood (Fazio-Londe syndrome) is characterised by progressive bilateral facial paralysis with various other manifestations: ptosis, dysphagia, dysrhythmia, dyspnoea and frequent respiratory infections. It may become generalised, leading to paralysis, amyotrophy and abnormally sharp osteotendinous reflexes. The course is severe in cases of respiratory insufficiency. It is caused by neuronal loss in the motor nuclei of the cranial nerves, at the level of the spinal bulb. Degeneration of the anterior horn cells of the spinal cord has also been reported. The mode of transmission is autosomal recessive.
