Peripheral neuropathy is common among patients with fragile X-associated tremor ataxia syndrome (FXTAS). Four patients wdth FXTAS are described with neuropathy as the presenting feature, two having received a prior diagnosis of Charcot-Marie-Tooth (CMT) disease. A fifth is described with neuropathy as the only clinical feature. A functional connection between FXTAS and neuropathy has been suggested by the presence of lamin A/C in the intranuclear, neuronal and astrocytic inclusions of FXTAS, since mutations in lamin A/C are known to give rise to an axonal form of CMT.
