The axonal type 2 Charcot-Marie-Tooth disease (CMT2) is phenotypically poorly characterized. Here the authors report a family with a Pro22Ser mutation in the neurofilament-light gene (NF-L; CMT2E) manifesting electrophysiologically as the demyelinating type 1 CMT (CMT1) and pathologically as an axonopathy with giant axons and accumulation of disorganized(More)
In order to identify early clinical features and survival predictors of supranuclear palsy (PSP) and multiple system atrophy (MSA), we compared the disease course of patients consecutively referred between 1987 and 1999 and followed to December 1999. Thirty-nine PSP and 74 MSA patients were diagnosed according to commonly accepted clinical criteria. Length(More)
The sensitivities and predictive values of visual, somatosensory, and brain auditory evoked potentials (EPs), cerebrospinal fluid oligoclonal banding (CSF-OB) and magnetic resonance imaging (MRI) were evaluated for the early diagnosis of clinically definite multiple sclerosis (CDMS). Paraclinical evidence of asymptomatic lesions allows a diagnosis of CDMS.(More)
The peripheral myelin protein 22 (PMP22) is a tetraspan membrane protein which is localised in the compact myelin of the peripheral nerves. In fibroblasts, where it was originally identified as growth arrest related factor 3 (Gas3), PMP22 has been shown to modulate cell proliferation; in the peripheral nervous system its roles are still debated. The(More)
Mutations in the gene encoding 27-kDa small heat-shock protein B1 (HSPB1) have been reported in association with Charcot-Marie-Tooth disease type 2F or dHMN type II. We describe an Italian patient with wasting and weakness of distal muscles, involving primarily and mostly the lower limbs and later the upper limbs, in which a novel mutation of HSPB1, T180I,(More)
OBJECTIVE To identify the molecular basis of a demyelinating Charcot-Marie-Tooth disease type 1 (CMT1) with presumed autosomal recessive inheritance. BACKGROUND CMT1, an inherited motor and sensory neuropathy with low nerve conduction velocities, is caused by dominantly inherited mutations in the genes of the peripheral myelin protein 22 (PMP22), myelin(More)
Here we describe clinical, neuropsychological and neuroradiological findings in 6 subjects belonging to two unrelated Italian cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) kindreds from the same geographic area who shared a common Arg1006Cys mutation. Subjects from Family A were virtually asymptomatic,(More)
BACKGROUND Recently, mutations affecting different domains of dynamin-2 (DNM2) were associated alternatively with autosomal dominant centronuclear myopathy or dominant intermediate (demyelinating and axonal) Charcot-Marie-Tooth disease (CMT) type B. OBJECTIVE To assess the etiologic role of DNM2 in CMT. METHODS We performed a mutational screening of(More)
OBJECTIVE In X-linked Charcot-Marie-Tooth disease (CMTX), electrophysiological and histopathological studies have suggested either a demyelinating or an axonal polyneuropathy. We report a CMTX family with a striking heterogeneity of nerve conductions between and within nerves. METHODS Two men and one woman have been studied by conduction velocities, sural(More)
Incidence rates for CNS tumours in children of age 0-14 years in the Region of Lombardy, Italy, during the period 1988-93 were analysed; survival probability updated to December 1995 was also estimated. CNS tumours defined according to the International Classification of Diseases for Oncology codes were actively searched for. CNS tumours were diagnosed in(More)
