Onset occurs in infancy or early childhood, usually before 3 years of age. Progression is slow until the teenage years at which point it may accelerate, resulting in severe disability. Symptoms are usually more severe and rapidly progressive than in the other more common Charcot-Marie-Tooth diseases. Some patients may never walk and solely use wheelchairs by the end of their first decade, while others may need only a cane (walking stick) or similar support through life. Dejerine-Sottas disease is characterized by moderate to severe lower and upper extremity weakness and loss of sensation, which occur mainly in the lower legs, forearms, feet and hands. Loss of muscle mass and reduced muscle tone can occur as the disease progresses. Other symptoms may include pain in the extremities, curvature of the spine, clawed hands, foot deformities, ataxia, peripheral areflexia, and slow acquisition of motor skills in childhood. Symptoms that are less common can include limitation of eye movements, other eye ...

Distal hereditary motor neuronopathies (dHMNs) are a clinically and genetically heterogeneous group of disorders in which motor neurons selectively undergo age-dependant degeneration. Mutations in the small heat-shock protein HSPB1 (HSP27) are responsible for one form of dHMN. In this study, we have analysed the effect of expressing a form of mutant HSPB1 in primary neuronal cells in culture. Mutant (P182L) but not wild-type HSPB1 led to the formation of insoluble intracellular aggregates and to the sequestration in the cytoplasm of selective cellular components, including neurofilament middle chain subunit (NF-M) and p150 dynactin. These findings suggest a possible pathogenic mechanism for HSPB1 whereby the mutation may lead to preferential motor neuron loss by disrupting selective components essential for axonal structure and transport.

Glycyl-tRNA synthetase (GARS) is one of 37 nuclear encoded amino acyl tRNA synthetases that function to attach amino acids onto their respective tRNA for protein translation.44 Since the discovery of GARS as a cause of dHMNV and CMT2D, mutations in three other amino acyl tRNAs have been identified as causes of intermediate CMT (DI-CMTC) (YARS, tyrosyl-tRNA synthetase),45 CMT2N (AARS, alanyl-tRNA synthetase)46 and autosomal recessive CMT2 (RI-CMTB) (KARS, lysyl-tRNA synthetase).47. In 2003, four different GARS mutations were discovered in five families with upper-limb predominant distal motor neuropathy (dHMNV or CMT2D).10 Six additional familial and sporadic cases of dHMN owing to GARS mutations have been reported.48-51 In an extended phenotype/genotype study of the original five families, 75% of affected family members presented in the second decade of life, with the majority functioning independently 40 years after disease onset.52 In one patient, weakness began in the lower limbs, ...
RATIONALE: Hereditary neuropathy with liability to pressure palsy (HNPP) is an episodic, multifocal neuropathy, with a typical clinical presentation of recurrent transient pressure palsies, which is induced by a PMP22 deletion. Another neuropathy caused by a PMP22 duplication is Charcot-Marie-Tooth disease type 1A (CMT1A). PMP22 is a gene coding a protein called peripheral myelin protein 22 (PMP22), which plays an essential role in the formation and maintenance of compact myelin. Coexistence of type 2 diabetes mellitus (T2DM) and CMT1A has been reported in many work, however HNPP patients with T2DM are rare, and comorbidity of HNPP and psoriasis has not been reported previously ...

The carrier status of the HMSN/ACC gene can be confirmed through genetic testing. If you have a family history of HMSN/ACC, you may wish to consult a genetic counselor to understand your chances of having a child affected with HMSN/ACC and discuss family planning alternatives.. A paediatrician and/or neurologist will conduct a clinical examination, as well as genetic testing to confirm diagnosis of HMSN/ACC. Additional testing may be recommended, such as a brain scan performed with highly precise radiography technology (cerebral tomography) or an analysis of the electrical activity in the arm and leg muscles (electromyogram).. Symptoms appear shortly after birth or during the first year of life and are characterized by a lack of muscle strength and a delay in the development of motor skills. HMSN/ACC results in a loss of mobility and developmental abnormalities in the spine, hands, and feet. In addition to the physical symptoms, HMSN/ACC also causes mild to moderate cognitive impairment.. Babies ...
Pat is a 69-year-old woman with Charcot-Marie-Tooth disease, or CMT. She had been experiencing the effects of CMT for more than thirty years, and her progressive motor sensory neuropathy had become severe enough to interfere with every aspect of her life. She could no longer play piano, balance well enough to climb up steps or get dressed easily or summon the energy to work for more than a couple of hours before taking a rest break. Pats form of CMT is CMT1A, which is the most common form of this autosomal dominant condition. Her symptoms were typical of CMT; patients typically endure progressive muscle wasting and weakness in the legs, and a later loss of hand strength, balance, coordination and fine motor skills.. Pats neurological disorder is hereditary, and the official position of the National Institute of Neurological Disorders and Stroke is that CMT has no cure. Decades ago, Pat had gone to a neurologist for electromyography, or EMG. The purpose of the procedure was to evaluate her ...

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

AU - Small, Kent W.. PY - 2003/10/1. Y1 - 2003/10/1. N2 - PURPOSE: To present the detailed clinical findings of a large family with hereditary motor and sensory neuropathy type VI (HMSN VI), a syndrome featuring optic atrophy. DESIGN: Observational case series. METHODS: A detailed history was obtained and physical examination was made of the extended family of the proband for evidence of neurologic dysfunction. The OPA1 gene was screened for mutations by direct DNA sequencing. RESULTS: Twelve of 97 family members examined are affected with signs of HMSN VI. Three other members have either optic atrophy or peripheral neuropathy, thus allowing an appreciation of the full clinical spectrum of disease. No mutations were found in the OPA1 gene. CONCLUSIONS: This family demonstrates the variable expressivity of ...
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 ...
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

Three metabolic disorders caused by channel mutations have been described: a renal Fanconi syndrome with mutations in NaPi-IIa causing impaired renal phosphate reabsorption (Magen et al., 2010, N Engl J Med 362:1102-09). ATP7A, encoding a copper transporter causing Menkes disease and occipital horn syndrome, can also be the cause of X-Linked Distal Hereditary Motor Neuropathy (Kennerson et al., 2010, Am J Hum Genet 86:343-52). Also, a susceptibility to thyrotoxic hypokaliemic paralysis can be caused by mutations in potassium channel Kir2.6 (Ryan et al., 2010, Cell 140:88-98).. Posted by Philippe Campeau, MD. ...
Spinal muscular atrophies (SMA, also known as hereditary motor neuropathies) and hereditary motor and sensory neuropathies (HMSN) are clinically and genetically heterogeneous disorders of the peripheral nervous system. Here we report that mutations in the TRPV4 gene cause congenital distal SMA, scapuloperoneal SMA, HMSN 2C. We identified three missense substitutions (R269H, R315W and R316C) affecting the intracellular N-terminal ankyrin domain of the TRPV4 ion channel in five families. Expression of mutant TRPV4 constructs in cells from the HeLa line revealed diminished surface localization of mutant proteins. In addition, TRPV4-regulated Ca(2+) influx was substantially reduced even after stimulation with 4alphaPDD, a TRPV4 channel-specific agonist, and with hypo-osmotic solution. In summary, we describe a new hereditary channelopathy caused by mutations in TRPV4 and present evidence that the resulting substitutions in the N-terminal ankyrin domain affect channel maturation, leading to reduced ...
Hereditary Sensory and Motor Neuropathy: A group of slowly progressive inherited disorders affecting motor and sensory peripheral nerves. Subtypes include HMSNs I-VII. HMSN I and II both refer to CHARCOT-MARIE-TOOTH DISEASE. HMSN III refers to hypertrophic neuropathy of infancy. HMSN IV refers to REFSUM DISEASE. HMSN V refers to a condition marked by a hereditary motor and sensory neuropathy associated with spastic paraplegia (see SPASTIC PARAPLEGIA, HEREDITARY). HMSN VI refers to HMSN associated with an inherited optic atrophy (OPTIC ATROPHIES, HEREDITARY), and HMSN VII refers to HMSN associated with retinitis pigmentosa. (From Adams et al., Principles of Neurology, 6th ed, p1343)
Charcot-Marie-Tooth type 1 disease (CMT1) and hereditary neuropathy with liability to pressure palsies (HNPP) are common inherited disorders of the peripheral nervous system. The majority of CMT1 patients have a 1.5Mb tandem duplication (CMT1A) in chromosome 17p11.2 while most HNPP patients have a deletion of the same 1.5 Mb region. The CMT1A duplication and HNPP deletion are the reciprocal products of an unequal crossing over event between misaligned flanking CMT1A-REP elements. We analysed 162 unrelated CMT1A duplication patients and HNPP deletion patients from 11 different countries for the presence of a recombination hotspot in the CMT1A-REP sequences. A hotspot for unequal crossing over between the misaligned flanking CMT1A-REP elements was observed through the detection of novel junction fragments in 76.9% of 130 unrelated CMT1A patients and in 71.9% of 32 unrelated HNPP patients. This recombination hotspot was also detected in eight out of 10 de novo CMT1A duplication and in two de novo HNPP

We report a large family with a multigenerational pedigree of HMSN with focally folded myelin sheaths. The family studied allowed us to uncover the genetic findings, clinical spectrum, and natural history of HMSN with focally folded myelin sheaths, and to highlight the significant intrafamily uniformity of clinical presentation.. Focally folded myelin sheaths are the pathologic hallmark of certain hereditary neuropathies of wide clinical spectrum. 11-14,21-26 Of the 23 cases reported, 10 patients came from five families, whereas 13 cases were sporadic. In two cases, an autosomal-dominant mode of inheritance was postulated. 24 The reports of Dayan et al., 27 Nordborg et a1., 28 and Lutschg et al. 29 were not included because published pathologic data were not detailed enough for a comparison with ours.. In our family, the genealogic study showing the high consanguinity rate represents strong evidence in favor of an autosomal-recessive pattern of inheritance, confirming the hypothesis postulated ...

Hereditary motor and sensory neuropathies progressively debilitate leg and arm movement and impair sensation. The wide variability in symptoms and genetic etiology, as well as the lethality of known mutations in mice, has delayed the development of model organisms. Francesca Achilli and colleagues made a dominant mutation in glycyl-tRNA synthetase (GARS), which appears in some cases of familial Chariot-Marie-Tooth (CMT) and infantile hereditary motor neuropathy (HMN). The mice have muscle weakness, loss of electrical conduction in neurons, and neuromuscular junction defects. An increasing number of nervous system diseases are linked with tRNA synthetase mutations, and this model should help determine the role of protein translation in these and other similar diseases..

Hereditary polyneuropathies known as Charcot-Marie-Tooth (CMT) polyneuropathies are genetically heterogeneous group of peripheral nerve disorders characterized by slow progressive weakness and atrophy of distal muscles, associated with mild to moderate sensation loss, weakened tendon reflexes and typical foot deformity. The most common subtypes are CMT1A, HNPP (hereditary neuropathy with liability to pressure palsies), CMTX1 and CMT1B. This research examined the type and frequency of mutations in genes involved in myelin construction (PMP22, GJB1 and MPZ) in CMT1 patients by MLPA and gene sequencing method. A total of 13 mutations in the PMP22 and GJB1 genes were found, of which five were new, unpublished. A similar ratio of CMT subtypes in the Republic of Croatia was found as in other European countries with the exception of absence of MPZ mutations. The results of neurograph parameters analysis indicate the differentiation of the demyelinating process and the axons degeneration as two ...

Abstract. BACKGROUND AND AIMS: Charcot-Marie-Tooth disease type 1A (CMT1A) is the most common type of hereditary neuropathy worldwide and diabetes mellitus (DM) is the most frequent cause of peripheral neuropathy in the Western world. CMT1A typically manifest as a predominant motor neuropathy, whilst, DM-related neuropathy often manifests as a predominant sensory disorder. There are some evidences that CMT1A patients that also had DM had a more severe neuropathy. Though the real frequency and the underlying mechanisms related to this association has not yet been addressed in the literature. We sought to characterize the ...
Oh my giddy aunt. Charcot-Marie-Tooth. When I was diagnosed, I too thought it might be useful to do some research. As it happens, with all the variations and other features, it seems to be an absolute goldmine for PhD candidates. All over the place, there are families and localities with their own barely discernible, finely calibrated differences from other families and other localities. By the time Id got through about 40 papers discussing half a dozen or a couple of hundred individuals and their associated genetic abnormalities, I thought Id had enough. Unless you go the whole hog as Kim Goodsell has done, there seems to be no way to find out what your own particular condition has in store for you. My diagnosis was for the Hereditary Neuropathy with Pressure Palsies version, not the classic Charcot-Marie-Tooth. So how come I had the whole deformed toes, ludicrous instep and wasting leg muscles of the classic diagnosis? As well as seeing my fathers hands deteriorate into the distinctive ...
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 ...

Hereditary motor and sensory neuropathy associated with agenesis of the corpus callosum (HMSN/ACC; Online Mendelian Inheritance in Man No. 218000) is a severe and progressive autosomal-recessive polyneuropathy associated with hypotonia, mental retardation, dysmorphism, variable degrees of agenesis of the CC, and visual/auditory hallucinations, resulting in death typically during the third decade (Dupré et al., 2003). Our group previously reported that the K+/Cl− cotransporter 3 (KCC3), encoded by the SLC12A6 gene, is disrupted in patients with this disorder (Howard et al., 2002). KCC3 belongs to a family of four K+/Cl− cotransporters that have crucial roles in ion homeostasis, cell volume regulation, and modulation of the cellular responses to GABA during neuronal development (Kahle et al., 2008). Structurally, KCC3 has 12 transmembrane domains and both the N and C termini extend into the cytoplasm (Hiki et al., 1999). The predominant mutation found in HMSN/ACC patients consists of a G ...
