We assessed pulmonary function in hereditary motor and sensory neuropathy. Fourteen neuropathy patients without spinal deformity (group 1), 14 with spinal deformity (group 2), and 16 individuals with idiopathic spinal deformity (group 3) matched to group 2 for age, height and Cobb angle, were included. Hereditary motor and sensory neuropathy severity was measured with Charcot-Marie-Tooth Neurop...

Two Japanese persons with consanguinous parents had a motor and sensory neuropathy of the hypertrophic type with excessive myelin outfolding in the myelinated fibers. A morphometric analysis of the biopsied sural nerve was made. Excessive myelin outfolding, segmental demyelination, and remyelination and decrease in the density of both large and small myelinated fibers were evident. Using linear...

The association between hereditary motor and sensory neuropathy (HMSN) and optic atrophy has been termed HMSN type VI. The autosomal dominant inheritance of this syndrome is reported. Three generations were affected with optic atrophy, which differed in some respects from classic dominant optic atrophy, and an asymptomatic, mainly sensory, neuropathy.

Silver syndrome (Silver spastic paraplegia syndrome) is a rare disorder of the peripheral nervous system that combines features of spastic paraparesis and peripheral neuropathy. The underlying genetic defects are two mutations in the BSCL2 gene which have been described in several families. Silver syndrome--related to the N88S mutation in the BSCL2 gene--is characterized by a spectrum of clinic...

At the time of its first description in 2004, MFN2 was considered the most frequently mutated gene in hereditary motor and sensory neuropathy type 2 (HMSN 2). However recent studies have shown that the frequency of MFN2 gene mutations in HMSN II patients is surprisingly low. To date, no systematic studies devoted to HMSN IIa in Poland have been carried out. In this study, we searched for MFN2 g...

There are two known autosomal dominant genes for the hereditary ulcero-mutilating neuropathies: SPTLC1 (hereditary sensory neuropathy type 1) and RAB7 (Charcot-Marie-Tooth disease type 2B). We report a family with autosomal dominant ulcero-mutilating neuropathy, developing in the teens and characterized by ulcers, amputations, sensory involvement in the feet but no motor features. Sequencing th...

OBJECTIVE To evaluate upper limb functioning, restrictions on participation and the independent contribution of upper and lower limb disability to participation in hereditary motor and sensory neuropathy 1a. DESIGN Descriptive cross-sectional study. SUBJECTS Forty-nine patients with hereditary motor and sensory neuropathy 1a. METHODS Perceived upper limb functioning was evaluated using th...
