| Outline of Final Research Achievements |
The hereditary motor sensory neuropathy with proximal dominancy (HMSN-P) is a slowly progressive intractable disease and some patients eventually require a tracheostomy with artificial ventilation, mimicking the clinical course of familial amyotrophic lateral sclerosis (FALS). The gene locus has been mapped on the chromosome 3; and the causative gene has been identified, TRK-fused gene (TFG). The purpose of this research is to clarify the global epidemiology, pathomechanism and therapeutic strategy for HMSN-P in collaboration with scientists in Brazil, Italy, USA and Korea. As we expected, new cases with TFG mutations are reported from Germany, Korea, Taiwan, USA and Brazil. We held International Hereditary Neuropathy Symposium in Kyoto at August 31, 2014 and discussed the pathological mechanism of HMSN-P. We agreed with the scientists that TGF mutation closely link with motor neuron disorders like FALS.
