The Thr124Met mutation in the peripheral myelin protein zero (MPZ) gene is associated with a clinically distinct Charcot-Marie-Tooth phenotype. (2/499)

We observed a missense mutation in the peripheral myelin protein zero gene (MPZ, Thr124Met) in seven Charcot-Marie-Tooth (CMT) families and in two isolated CMT patients of Belgian ancestry. Allele-sharing analysis of markers flanking the MPZ gene indicated that all patients with the Thr124Met mutation have one common ancestor. The mutation is associated with a clinically distinct phenotype characterized by late onset, marked sensory abnormalities and, in some families, deafness and pupillary abnormalities. Nerve conduction velocities of the motor median nerve vary from <38 m/s to normal values in these patients. Clusters of remyelinating axons in a sural nerve biopsy demonstrate an axonal involvement, with axonal regeneration. Phenotype-genotype correlations in 30 patients with the Thr124Met MPZ mutation indicate that, based on nerve conduction velocity criteria, these patients are difficult to classify as CMT1 or CMT2. We therefore conclude that CMT patients with slightly reduced or nearly normal nerve conduction velocity should be screened for MPZ mutations, particularly when additional clinical features such as marked sensory disturbances, pupillary abnormalities or deafness are also present.  (+info)

Central visual, acoustic, and motor pathway involvement in a Charcot-Marie-Tooth family with an Asn205Ser mutation in the connexin 32 gene. (3/499)

BACKGROUND: X linked dominant Charcot-Marie-Tooth disease (CMT1X) is an inherited motor and sensory neuropathy that mainly affects the peripheral nervous system. CMT1X is associated with mutations in the gap junction protein connexin 32 (Cx32). Cx32 is expressed in Schwann cells and oligodendrocytes in the peripheral (PNS) and in the (CNS) respectively. METHODS: A CMT1X family with a Cx32 mutation was examined clinically and electrophysiologically to determine whether PNS, or CNS, or both pathways were affected. RESULTS: In a CMT1X family a novel mutation (Asn205Ser) was found in the fourth transmembrane domain of Cx32. The patients showed typical clinical and electrophysiological abnormalities in the PNS, but in addition visual, acoustic, and motor pathways of the CNS were affected subclinically. This was indicated by pathological changes in visually evoked potentials (VEPs), brainstem auditory evoked potentials (BAEPs), and central motor evoked potentials (CMEPs). CONCLUSIONS: These findings underscore the necessity of a careful analysis of CNS pathways in patients with CMT and Cx32 mutations. Abnormal electrophysiological findings in CNS pathway examinations should raise the suspicion of CMTX and a search for gene mutations towards Cx32 should be considered.  (+info)

Motor nerve conduction velocity in spinal muscular atrophy of childhood. (4/499)

The ulnar and posterior tibial conduction velocities were measured in 29 children with spinal muscular atrophy, 14 of whom had the servere form of the disease. The ulnar nerve velocity was slow in 12 of the 14 severely affected infants, but normal or fast in 11 of 14 children less severely affected. The corresponding results for the posterior tibial nerve were slow velocities in 11 of 12 infants in the severe group and normal or fast in all 11 infants less severely affected. The difficulty in distinguishing infantile spinal muscular atrophy from peripheral neuropathy is emphasized.  (+info)

Study on the gene and phenotypic characterisation of autosomal recessive demyelinating motor and sensory neuropathy (Charcot-Marie-Tooth disease) with a gene locus on chromosome 5q23-q33. (5/499)

OBJECTIVES: To report the occurrence of the autosomal recessive form of demyelinating Charcot-Marie-Tooth disease (CMT) with a locus on chromosome 5q23-33 in six non-related European families, to refine gene mapping, and to define the disease phenotype. METHODS: In an Algerian patient with autosomal recessive demyelinating CMT mapped to chromosome 5q23-q33 the same unique nerve pathology was established as previously described in families with a special form of autosomal recessive demyelinating CMT. Subsequently, the DNA of patients with this phenotype was tested from five Dutch families and one Turkish family for the 5q23-q33 locus. RESULTS: These patients and the Algerian families showed a similar and highly typical combination of clinical and morphological features, suggesting a common genetic defect. A complete cosegregation for markers D5S413, D5S434, D5S636, and D5S410 was found in the families. Haplotype construction located the gene to a 7 cM region between D5S643 and D5S670. In the present Dutch families linkage disequilibrium could be shown for various risk alleles and haplotypes indicating that most of these families may have inherited the underlying genetic defect form a common distant ancestor. CONCLUSIONS: This study refines the gene localisation of autosomal recessive demyelinating CMT, mapping to chromosome 5q23-33 and defines the phenotype characterised by a precocious and rapidly progressive scoliosis in combination with a relatively mild neuropathy and a unique pathology. Morphological alterations in Schwann cells of the myelinated and unmyelinated type suggest the involvement of a protein present in both Schwann cell types or an extracellular matrix protein rather than a myelin protein. The combination of pathological features possibly discerns autosomal recessive demyelinating CMT with a gene locus on chromosome 5q23-33 from other demyelinating forms of CMT disease.  (+info)

Altered formation of hemichannels and gap junction channels caused by C-terminal connexin-32 mutations. (6/499)

Hexamers of connexins (Cxs) form hemichannels that dock tightly in series via their extracellular domains to give rise to gap junction channels. Here we examined the ability of a variety of C-terminal Cx32 mutations, most of which have been identified in X-linked Charcot-Marie-Tooth disease, to form hemichannels and to complete gap junction channels using the Xenopus oocyte system. First, we show that undocked wild-type Cx32 hemichannels at the plasma membrane can be detected as opening channels activated by depolarization. We have been able to estimate the efficiency of assembly of complete channels by measuring the time-dependent incorporation of preformed hemichannels into gap junction channels after cell-to-cell contact. These data offer strong evidence that hemichannels are the direct precursors of gap junction channels. Of 11 Cx32 mutants tested, a group of 5 mutations prevented the formation of functional hemichannels at the cell surface, whereas 4 mutations were fully able to form precursors but reduced the ability of hemichannels to assemble into complete channels, and 2 mutants formed channels normally. The data revealed that a minimum length of human Cx32 including the residue Arg-215 is required for the expression of hemichannels at the cell surface and that the efficiency of hemichannel incorporation into complete channels decreased gradually with the progressive shortening of the cytoplasmic C-terminal domain.  (+info)

Axonal phenotype of Charcot-Marie-Tooth disease associated with a mutation in the myelin protein zero gene. (7/499)

A French family had Charcot-Marie-Tooth disease type 2 (CMT2) which was characterised by late onset of peripheral neuropathy involvement, Argyll Robertson-like pupils, dysphagia, and deafness. Electrophysiological studies and nerve biopsy defined the neuropathy as axonal type. Genetic analysis of myelin protein zero (MPZ) found a mutation in codon 124 resulting in substitution of threonine by methionine. One of the patients, presently 30 years old, showed only Argyll Robertson-like pupils as an objective sign but no clinical or electrophysiological signs of peripheral neuropathy.  (+info)

A unique point mutation in the PMP22 gene is associated with Charcot-Marie-Tooth disease and deafness. (8/499)

Charcot-Marie-Tooth disease (CMT) with deafness is clinically distinct among the genetically heterogeneous group of CMT disorders. Molecular studies in a large family with autosomal dominant CMT and deafness have not been reported. The present molecular study involves a family with progressive features of CMT and deafness, originally reported by Kousseff et al. Genetic analysis of 70 individuals (31 affected, 28 unaffected, and 11 spouses) revealed linkage to markers on chromosome 17p11.2-p12, with a maximum LOD score of 9.01 for marker D17S1357 at a recombination fraction of .03. Haplotype analysis placed the CMT-deafness locus between markers D17S839 and D17S122, a approximately 0.6-Mb interval. This critical region lies within the CMT type 1A duplication region and excludes MYO15, a gene coding an unconventional myosin that causes a form of autosomal recessive deafness called DFNB3. Affected individuals from this family do not have the common 1.5-Mb duplication of CMT type 1A. Direct sequencing of the candidate peripheral myelin protein 22 (PMP22) gene detected a unique G-->C transversion in the heterozygous state in all affected individuals, at position 248 in coding exon 3, predicted to result in an Ala67Pro substitution in the second transmembrane domain of PMP22.  (+info)

Charcot-Marie-Tooth disease (CMT) is the most common inherited neuromuscular disease and is characterized by considerable clinical and genetic heterogeneity. We previously reported a Russian family with autosomal dominant axonal CMT and assigned the locus underlying the disease (CMT2F; OMIM 606595) to chromosome 7q11-q21 (ref. 2). Here we report a missense mutation in the gene encoding 27-kDa small heat-shock protein B1 (HSPB1, also called HSP27) that segregates in the family with CMT2F. Screening for mutations in HSPB1 in 301 individuals with CMT and 115 individuals with distal hereditary motor neuropathies (distal HMNs) confirmed the previously observed mutation and identified four additional missense mutations. We observed the additional HSPB1 mutations in four families with distal HMN and in one individual with CMT neuropathy. Four mutations are located in the Hsp20-alpha-crystallin domain, and one mutation is in the C-terminal part of the HSP27 protein. Neuronal cells transfected with mutated HSPB1
UniProtKB/Swiss-Prot : 73 Charcot-Marie-Tooth disease 4B2: A recessive demyelinating form of Charcot-Marie-Tooth disease, a disorder of the peripheral nervous system, characterized by progressive weakness and atrophy, initially of the peroneal muscles and later of the distal muscles of the arms. Charcot-Marie-Tooth disease is classified in two main groups on the basis of electrophysiologic properties and histopathology: primary peripheral demyelinating neuropathies (designated CMT1 when they are dominantly inherited) and primary peripheral axonal neuropathies (CMT2). Demyelinating neuropathies are characterized by severely reduced nerve conduction velocities (less than 38 m/sec), segmental demyelination and remyelination with onion bulb formations on nerve biopsy, slowly progressive distal muscle atrophy and weakness, absent deep tendon reflexes, and hollow feet. By convention autosomal recessive forms of demyelinating Charcot-Marie-Tooth disease are designated CMT4 ...

Although most mutations result in loss of function, several studies have reported that some retain the ability to form homotypic intercellular channels. To gain insight into the molecular defect of three functional CMTX variants, S26L, Δ111-116 and R220stop, we have used several fluorescent tracers of different size and ionic charge to compare their permeation properties to those of wild-type Cx32. ...

Mutations in the gap junction geneconnexin32(Cx32) cause the X-linked form of Charcot-Marie-Tooth disease, an inherited demyelinating neuropathy. More than 130 different mutations have been described, affecting all portions of the Cx32 protein. In transfected cells, the mutant Cx32 proteins encoded by someCx32mutations fail to reach the cell surface; other mutant proteins reach the cell surface, but only one of these forms functional gap junctions. In peripheral nerve, Cx32 is localized to incisures and paranodes, regions of noncompact myelin within the myelin sheath. This localization suggests that Cx32 forms
Charcot-Marie-Tooth disease (CMT) is the name for a group of inherited disorders of nerve conduction causing weakness and mild loss of sensation in the limbs.. CMT affects the peripheral nerves, those groups of nerve cells carrying information to and from the spinal cord. CMT decreases the ability of these nervesto carry motor commands to muscles, especially those furthest from the spinal cord in the feet and hands. As a result, these muscles are weakened. CMT also causes mild sensory loss.. CMT is named for the three neurologists who first described it, and does notinvolve the teeth in any way. It is also known as hereditary motor and sensory neuropathy, and is also sometimes called peroneal muscular atrophy, referring to the muscles in the leg affected early on in the disease.. The symptoms grouped together under the name CMT can be caused by any of at least six different genetic defects. Most of the defects, identified as of early 1998, affect myelin, the coating that insulates nerve cells to ...
Charcot-Marie-Tooth neuropathies (CMT) are inherited neuromuscular disorders caused by length-dependent neurodegeneration of peripheral nerves. More than 900 mutations in 60 different genes are responsible for Charcot-Marie-Tooth neuropathy. Despite significant progress in therapeutic strategies, the disease remains incurable. The increasing number of genes linked to the disease, and their considerable clinical and genetic heterogeneity renders the development of these strategies particularly challenging. In this context, cellular and animals models provide powerful tools. Efficient motor and sensory tests have been developed to assess the behavioral phenotype in transgenic animal models (rodents and fly). When these models reproduce a phenotype comparable to CMT, they allow therapeutic approaches and the discovery of modifiers and biomarkers. The majority of these models concern the demyelinating form (type 1) of the disease. The axonal form (type 2) is less common. Both forms can further be ...

Charcot-Marie-Tooth disease (CMT) is a group of clinically and genetically heterogeneous peripheral neuropathies. HSPB8 gene encodes heat shock protein 22 (HSP22) which belongs to the superfamily of small stress induced proteins. Mutations in HSPB8 are implicated to CMT2L and distal hereditary motor …
Patients with Charcot-Marie-Tooth neuropathy and gene targeting in mice revealed an essential role for the SH3TC2 gene in peripheral nerve myelination. SH3TC2 expression is restricted to Schwann cells in the peripheral nervous system, and the gene product, SH3TC2, localizes to the perinuclear recycling compartment. Here, we show that SH3TC2 interacts with the small guanosine triphosphatase Rab11, which is known to regulate the recycling of internalized membranes and receptors back to the cell surface. Results of protein binding studies and transferrin receptor trafficking are in line with a role of SH3TC2 as a Rab11 effector molecule. Consistent with a function of Rab11 in Schwann cell myelination, SH3TC2 mutations that cause neuropathy disrupt the SH3TC2/Rab11 interaction, and forced expression of dominant negative Rab11 strongly impairs myelin formation in vitro. Our data indicate that the SH3TC2/Rab11 interaction is relevant for peripheral nerve pathophysiology and place endosomal recycling on the
A potential new treatment strategy for patients with Charcot-Marie-Tooth disease is on the horizon, thanks to research by neuroscientists now at the University at Buffalos (UBs) Hunter James Kelly Research Institute and their colleagues in Italy and England. The institute is the research arm of the Hunters Hope Foundation, established in 1997 by Jim Kelly, Buffalo Bills Hall of Fame quarterback, and his wife, Jill, after their infant son Hunter was diagnosed with Krabbe leukodystrophy, an inherited fatal disorder of the nervous system. Hunter died in 2005 at the age of eight. The institute conducts research on myelin and its related diseases with the goal of developing new ways of understanding and treating conditions such as Krabbe disease and other leukodystrophies. Charcot-Marie-Tooth or CMT disease, which affects the peripheral nerves, is among the most common of hereditary neurological disorders; it is a disease of myelin and it results from misfolded proteins in cells that produce ...
Congenital hypomyelinating neuropathy (CHN) is characterized clinically by early onset of hypotonia, areflexia, distal muscle weakness, and very slow nerve conduction velocities. {7,8:Warner et al. (1997, 1998)} noted that pathologic findings on sural nerve biopsies show hypomyelination of most or all fibers. Based on these findings, CHN is considered to be a result of congenital impairment in myelin formation. There has been some controversy and difficulty in differentiating congenital hypomyelination from Dejerine-Sottas syndrome (DSS; {145900}), because there is considerable overlap in clinical presentation. Based on pathologic findings of sural nerve biopsies (the absence of active myelin breakdown and the paucity of the onion bulbs in CHN and the presence of demyelination/remyelination and an abundance of well-organized onion bulbs in DSS; see {1:Balestrini et al., 1991}), CHN is considered to result from a congenital impairment in myelin formation, whereas DSS is thought to be due to ...

Charcot-Marie-Tooth (CMT) disease is one of the most common inherited neuropathies. Recently, three CMT1-associated point mutations (I43N, T51P, and I52T) were discovered in the abundant peripheral myelin protein P2. These mutations trigger abnormal myelin structure, leading to reduced nerve conduction velocity, muscle weakness, and distal limb atrophy. P2 is a myelin-specific protein expressed by Schwann cells that binds to fatty acids and membranes, contributing to peripheral myelin lipid homeostasis. We studied the molecular basis of the P2 patient mutations. None of the CMT1-associated mutations alter the overall folding of P2 in the crystal state. P2 disease variants show increased aggregation tendency and remarkably reduced stability, T51P being most severe. In addition, P2 disease mutations affect protein dynamics. Both fatty acid binding by P2 and the kinetics of its membrane interactions are affected by the mutations. Experiments and simulations suggest opening of the β barrel in T51P, ...
Three recurrent mutations were also identified during sequencing. Two families (nos. 264 and 265) showed a previously reported nonsense mutation predicting truncation of the protein at amino acid 220. [17] One family (no. 69) showed a codon 139 valine right arrow methionine missense mutation, also in the third transmembrane domain. [9] Another family (no. 269) showed recurrence of the codon 156 leucine right arrow arginine missense mutation located in the second extracellular loop. [9] None of the reported families with the same mutation are known to be related. In most cases, families with the same mutation are from different geographic regions. For example, family 69 is from New York, and the other two families with the identical mutation are from South Dakota and Michigan, with no known New York connection.. Nine families analyzed had no mutation within the coding region of Cx32. Seven of these represent sporadic cases, one has affected members in only two generations, and another is a large, ...

Mitofusin-2 (MFN2) is a mitochondrial outer-membrane protein that plays a pivotal role in mitochondrial dynamics in most tissues, yet mutations in MFN2, which cause Charcot-Marie-Tooth disease type 2A (CMT2A), primarily affect the nervous system. We generated a transgenic mouse model of CMT2A that developed severe early onset vision loss and neurological deficits, axonal degeneration without cell body loss, and cytoplasmic and axonal accumulations of fragmented mitochondria. While mitochondrial aggregates were labeled for mitophagy, mutant MFN2 did not inhibit Parkin-mediated degradation, but instead had a dominant negative effect on mitochondrial fusion only when MFN1 was at low levels, as occurs in neurons. Finally, using a transgenic approach, we found that augmenting the level of MFN1 in the nervous system in vivo rescued all phenotypes in mutant MFN2R94Q-expressing mice. These data demonstrate that the MFN1/MFN2 ratio is a key determinant of tissue specificity in CMT2A and indicate that ...

Missense mutations (K141N and K141E) in the α-crystallin domain of the small heat shock protein HSPB8 (HSP22) cause distal hereditary motor neuropathy (distal HMN) or Charcot-Marie-Tooth neuropathy type 2L (CMT2L). The mechanism through which mutant HSPB8 leads to a specific motor neuron disease phenotype is currently unknown. To address this question, we compared the effect of mutant HSPB8 in primary neuronal and glial cell cultures. In motor neurons, expression of both HSPB8 K141N and K141E mutations clearly resulted in neurite degeneration, as manifested by a reduction in number of neurites per cell, as well as in a reduction in average length of the neurites. Furthermore, expression of the K141E (and to a lesser extent, K141N) mutation also induced spheroids in the neurites. We did not detect any signs of apoptosis in motor neurons, showing that mutant HSPB8 resulted in neurite degeneration without inducing neuronal death. While overt in motor neurons, these phenotypes were only very mildly ...
Charcot-Marie-Tooth disease type 1A (CMT1A) is caused by a 1.4-Mb duplication on chromosome 17p11.2, which contains the peripheral myelin protein 22 (PMP22), a protein primarily expressed in myelinating Schwann cells (1, 2). In this issue, Zhao et al. treated two rodent models of CMT1A with PMP22-targeting antisense oligonucleotides (ASOs)and showed a 35% reduction in PMP22 mRNA (3). This reduction was not only adequate in slowing disease progression, but also improved the CMT1A-associated phenotypes in both models. These results are exciting for CMT1A researchers for several reasons. First, CMT1A is the most common inherited neuropathy, affecting 1:5,000 individuals. Second, severity of CMT1A appears to be dependent on PMP22 copy number, as patients with 4 copies of PMP22 have more severe neuropathy than typical CMT1A patients, who have 3 copies of PMP22 (4). Additionally, patients with missense mutations in PMP22 develop neuropathies that are similar to CMT1A (5). Taken together, these data ...
OMIM : 58 Hereditary neuropathy with or without age-related macular degeneration is a complex autosomal dominant syndrome characterized by a variable peripheral neuropathy resembling demyelinating Charcot-Marie-Tooth disease (see, e.g., CMT1A, 118220) and/or axonal CMT (see, e.g., CMT2A1, 118210) with sensorimotor impairment mainly of the distal lower extremities, or spinal CMT, also known as distal hereditary motor neuropathy (see, e.g., HMN1; 182960) with intact sensation. Age-related macular degeneration, if present, shows very late onset in the seventies or eighties. In addition, some patients may show hyperelasticity of the skin or joints. The age at onset of neuropathy and severity of the disorder is highly variable, even within families (summary by Auer-Grumbach et al., 2011). For a phenotypic description and a discussion of genetic heterogeneity of age-related macular degeneration, see 603075. (608895) ...
The overall goal of my laboratory is to understand the molecular mechanisms of neuromuscular diseases using in vitro and animal modeling, based on insights from human genetics, to develop novel therapeutic agents. We are particularly interested in inherited neuropathy (Charcot-Marie-Tooth disease), and amyotrophic lateral sclerosis (ALS). The molecular pathways defined by genes mutated in hereditary neuromuscular diseases provide insight into molecular pathogenesis, and are potential candidates for therapeutic manipulation. To investigate mechanisms of motor neuron disease/ALS we are exploring the role of mutations in both the repeat expansion in the C9ORF72 gene, and point mutations in the TARDBP gene, using human induced pluripotent stem cell (iPSC)-derived motor neurons and mouse models. To investigate Charcot-Marie-Tooth disease we are studying (i) the mechanism of mutations in the Mitofusin 2 gene in axonal CMT, and (ii) the use of iPSC-derived Schwann cells from patients with CMT type 1A ...
Charcot-Marie-Tooth disease type 1A (CMT1A) is caused by duplication of peripheral myelin protein 22 (PMP22) and is the most common hereditary peripheral neuropathy. CMT1A is characterized by demyelination and axonal loss, which underlie slowed motor nerve conduction velocity (MNCV) and reduced compound muscle action potentials (CMAP) in patients. There is currently no known treatment for this disease. Here, we show that antisense oligonucleotides (ASOs) effectively suppress PMP22 mRNA in affected nerves in 2 murine CMT1A models. Notably, initiation of ASO treatment after disease onset restored myelination, MNCV, and CMAP almost to levels seen in WT animals. In addition to disease-associated gene expression networks that were restored with ASO treatment, we also identified potential disease biomarkers through transcriptomic profiling. Furthermore, we demonstrated that reduction of PMP22 mRNA in skin biopsies from ASO-treated rats is a suitable biomarker for evaluating target engagement in ...
Charcot-Marie-Tooth (CMT) disease is the most common inherited neurologic disorder. CMT is characterized by inherited neuropathies without known metabolic derangements.
This gene is a member of the myotubularin family of phosphoinositide lipid phosphatases. The encoded protein possesses phosphatase activity towards phosphatidylinositol-3-phosphate and phosphatidylinositol-3,5-bisphosphate. Mutations in this gene are a cause of Charcot-Marie-Tooth disease type 4B, an autosomal recessive demyelinating neuropathy. Alternatively spliced transcript variants encoding multiple isoforms have been found for this gene. [provided by RefSeq, Aug 2011 ...
Mutations in heat shock 27 kDa protein 1 (HSP27 or HSPB1) cause distal hereditary motor neuropathy (dHMN) or Charcot-Marie-Tooth disease type 2 F (CMT2F) according to unknown factors. Mutant HSP27 proteins affect axonal transport by reducing acetylated tubulin. We generated a transgenic mouse model overexpressing HSP27-S135F mutant protein driven by Cytomegalovirus (CMV) immediate early promoter. The mouse phenotype was similar to dHMN patients in that they exhibit motor neuropathy. To determine the phenotypic aberration of transgenic mice, behavior test, magnetic resonance imaging (MRI), electrophysiological study, and pathology were performed. Rotarod test showed that founder mice exhibited lowered motor performance. MRI also revealed marked fatty infiltration in the anterior and posterior compartments at calf level. Electrophysiologically, compound muscle action potential (CMAP) but not motor nerve conduction velocity (MNCV) was reduced in the transgenic mice. Toluidine staining with semi-thin
Approximately four hundred mutations of the GJB1 gene have been identified in people with X-linked Charcot-Marie-Tooth disease (CMTX).[14] CMTX is predominantly classified with symptoms related to muscle weakness and sensory problems, especially in the outer extremities of the limbs.[8] CMTX is the second most common type of CMT (about 10% of all patients) and is transmitted as an x-linked dominant trait.[7] It is categorised by the lack of male-to-male transmission of the mutated GJB1 gene and the differences in severity between heterozygous women and hemizygous men, with the later being more severely affected.[11]. Most of the mutations of the GJB1 gene switch or change a single amino acid in the gap junction (connexin-32) protein, although some may result in a protein of irregular size.[7][11][13][14] Some of these mutations also cause hearing loss in patients with CMTX.[14] Currently it is unknown how the mutations of the GJB1 gene lead to these specific features of Charcot-Marie-Tooth ...
