In conclusion, mutations in SH3TC2 are responsible for 26% of Greek patients with suspected CMT4, identifying CMT4C as the most common recessive demyelinating neuropathy in the Greek population, in accordance with other Mediterranean cohorts.
Charcot-Marie-Tooth disease type 4C (CMT4C) is an autosomal recessive (AR) demyelinating neuropathy associated to SH3TC2 mutations, characterized by early onset, spine deformities, and cranial nerve involvement.
Our study therefore highlights the inherent evolutionary link between SH3TC2 and peripheral nerve myelination, pointing also towards a molecular mechanism underlying the specific demyelinating neuropathy that characterizes CMT4C.
Charcot-Marie-Tooth (CMT) neuropathy type 4C (CMT4C) is an autosomal recessive (AR), demyelinating neuropathy with early spine deformities caused by mutations in the SH3TC2 gene.
