Summaries for Roussy-Levy Syndrome

About this section
NIH Rare Diseases:42 Roussy levy syndrome is an autosomal dominant disease with the clinical characteristics of charcot-marie-tooth (cmt) disease type 1 plus a static tremor in the hands and gait ataxia.  the disease usually begins in infancy and is benign until adolescence. it is characterized by severe alterations in nerve conduction and sensory dysfunction. roussy levy syndrome may result from the classic cmt1a pmp22 duplication or a heterozygous mutation in the myelin protein zero (mpz) gene (mutations in this gene are also associated with cmt1b). treatment is symptomatic and supportive. last updated: 5/25/2011

MalaCards based summary: Roussy-Levy Syndrome, also known as roussy-lévy syndrome, is related to charcot-marie-tooth disease, type 1a and hereditary neuropathies, and has symptoms including decreased nerve conduction velocity, gait disturbance and reduced tendon reflexes. An important gene associated with Roussy-Levy Syndrome is MPZ (myelin protein zero), and among its related pathways is Neural Crest Differentiation. The compounds dihydroprogesterone and dihydrotestosterone have been mentioned in the context of this disorder.
