Charcot-Marie-tooth disease type 2A: An update on pathogenesis and therapeutic perspectives
Neurobiol Dis. 2024 Mar 5:106467. doi: 10.1016/j.nbd.2024.106467. Online ahead of print.ABSTRACTMutations in the gene encoding MFN2 have been identified as associated with Charcot-Marie-Tooth disease type 2A (CMT2A), a neurological disorder characterized by a broad clinical phenotype involving the entire nervous system. MFN2, a dynamin-like GTPase protein located on the outer mitochondrial membrane, is well-known for its involvement in mitochondrial fusion. Numerous studies have demonstrated its participation in a network crucial for various other mitochondrial functions, including mitophagy, axonal transport, and its cont...

Skeletal muscle involvement in biallelic < em > SORD < /em > mutations: case report and review of the literature
Acta Myol. 2023 Dec 20;42(4):113-117. doi: 10.36185/2532-1900-323. eCollection 2023.ABSTRACTBiallelic mutations in the sorbitol dehydrogenase (SORD) gene have been identified as a genetic cause of autosomal recessive axonal Charcot-Marie-Tooth disease 2 (CMT2) and distal hereditary motor neuropathy (dHMN). We herein review the main phenotypes associated with SORD mutations and report the case of a 16-year-old man who was referred to our outpatient clinic for a slowly worsening gait disorder with wasting and weakness of distal lower limbs musculature. Since creatine phosphokinase (CPK) values were persistently raised (1.5fo...
