As the rare disease community strives to better understand CMT4JA rare inherited peripheral neuropathy often characterized by rapidly progressive, asymmetrical upper and lower extremity weakness, muscle atrophy leading to handicap, and respiratory issues with no available treatment. CMT4J is a recessive subtype of CMT caused by a variant, also referred to as a mutation, in the FIG4 gene., consider these tools and partner sites for continued learning about life with this disease.
CMT4J Clinical Trials
There is a growing body of research on Charcot-Marie-ToothThe most common inherited motor and sensory neuropathies, composed of a group of pathologically and genetically distinct subtypes ranging from slowly to rapidly progressive disease. CMT is further classified based on the genetic mutation or variant involved – for instance, CMT4A, CMT4B, etc. disease and CMT4J in particular, as well as the various FIG4 variants that cause it. This research is intended to fuel advances for the CMT4J patient and healthcare community.
There are a limited number of trials related to CMT4J. All current trials are listed on ClinicalTrials.gov.
