<div class="spaceAbove">Dejerine-Sottas neuropathy is a demyelinating peripheral neuropathy with onset in infancy. It can show autosomal dominant or recessive inheritance. Affected individuals have delayed motor development due to severe distal motor and sensory impairment, resulting in difficulties in gait. Some patients have generalized hypotonia in infancy. Other features may include pes cavus, scoliosis, and sensory ataxia. Nerve conduction velocities are severely decreased (sometimes less than 10 m/s), and sural nerve biopsy shows severe loss of myelinated fibers (summary by Baets et al., 2011).</div>

<div class="spaceAbove">Charcot-Marie-Tooth disease is a sensorineural peripheral polyneuropathy. Affecting approximately 1 in 2,500 individuals, Charcot-Marie-Tooth disease is the most common inherited disorder of the peripheral nervous system (Skre, 1974). Autosomal dominant, autosomal recessive, and X-linked forms have been recognized. Classification On the basis of electrophysiologic properties and histopathology, CMT has been divided into primary peripheral demyelinating (type 1, or HMSNI) and primary peripheral axonal (type 2, or HMSNII) neuropathies. The demyelinating neuropathies classified as CMT type 1 are characterized by severely reduced motor NCVs (less than 38 m/s) and segmental demyelination and remyelination with onion bulb formations on nerve biopsy. The axonal neuropathies classified as CMT type 2 are characterized by normal or mildly reduced NCVs and chronic axonal degeneration and regeneration on nerve biopsy (see CMT2A1; 118210). Distal hereditary motor neuropathy (dHMN) (see 158590), or spinal CMT, is characterized by exclusive motor involvement and sparing of sensory nerves (Pareyson, 1999). McAlpine (1989) proposed that the forms of CMT with very slow nerve conduction be given the gene symbol CMT1A (118220) and CMT1B, CMT1A being the gene on chromosome 17 and CMT1B being the gene on chromosome 1. CMT2 was the proposed symbol for the autosomal locus responsible for the moderately slow nerve conduction form of the disease (axonal). For a phenotypic description and discussion of genetic heterogeneity of the various subtypes of CMT, see CMTX1 (302800), CMT2A1 (118210), CMT3 (DSS; 145900), CMT4A (214400), and CMTDIB (606482). Genetic Heterogeneity of Autosomal Dominant Demyelinating CMT1 Autosomal dominant demyelinating CMT1 is a genetically heterogeneous disorder and can be caused by mutations in different genes; see CMT1A (118220), CMT1C (601098), CMT1D (607678), CMT1E (607734), CMT1F (607734), CMT1G (618279), CMT1H (619764), CMT1I (619742), and CMT1J (620111). See also 608236 for a related phenotype characterized by isolated slowed nerve conduction velocities (NCVs).</div>

<div class="spaceAbove">GJB1 disorders are typically characterized by peripheral motor and sensory neuropathy with or without fixed CNS abnormalities and/or acute, self-limited episodes of transient neurologic dysfunction (especially weakness and dysarthria). Peripheral neuropathy typically manifests in affected males between ages five and 25 years. Although both men and women are affected, manifestations tend to be less severe in women, some of whom may remain asymptomatic. Less commonly, initial manifestations in some affected individuals are stroke-like episodes (acute fulminant episodes of reversible CNS dysfunction).</div>

<div class="spaceAbove">GDAP1-related hereditary motor and sensory neuropathy (GDAP1-HMSN) is a peripheral neuropathy (also known as a subtype of Charcot-Marie-Tooth disease) that typically affects the lower extremities earlier and more severely than the upper extremities. As the neuropathy progresses, the distal upper extremities also become severely affected. Proximal muscles can also become weak. Age at onset ranges from infancy to early childhood. In most cases, disease progression causes disabilities within the first or second decade of life. At the end of the second decade, most individuals are wheelchair bound. Disease progression varies considerably even within the same family. The neuropathy can be either of the demyelinating type with reduced nerve conduction velocities or the axonal type with normal nerve conduction velocities. Vocal cord paresis is common. Intelligence is normal. Life expectancy is usually normal, but on occasion may be reduced because of secondary complications.</div>

<div class="spaceAbove">Charcot-Marie-Tooth disease is a clinically and genetically heterogeneous 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. Classification CMT neuropathy is subdivided into CMT1 (see 118200) and CMT2 (see 118210) types on the basis of electrophysiologic and neuropathologic criteria. CMT1, or hereditary motor and sensory neuropathy type I (HMSN I), is a demyelinating neuropathy, whereas CMT2, or HMSN II, is an axonal neuropathy. Most patients with CMT are classified as having CMT1 or CMT2 by use of a cut-off value of 38 m/s for the motor median nerve conduction velocity (NCV). However, in some families with CMT, patients have motor median NCVs ranging from 25 to 45 m/s. Families of this type were reported by Salisachs (1974) and Davis et al. (1978). Davis et al. (1978) proposed that this form be designated 'intermediate' CMT. Claeys et al. (2009) stated that some CMT families may have an even broader range of NCV than 25 to 45 m/s, with the lowest levels around 25 and the highest levels within the normal range (50+ m/s). They also suggested that the term 'intermediate' should not be used to describe a single NCV value, but rather the CMT subtype at the level of the family (e.g., in families with a range or combinations of NCV values). Berciano et al. (2017) provided a detailed review of the different forms of intermediate CMT, noting that diagnoses may be controversial because of variable classification issues. The authors presented an algorithm for the interpretation of electrophysiologic studies in CMT, and suggested that nerve conduction studies should be conducted on the upper arm (axilla to elbow). They noted that distal axonal degeneration can result in secondary myelination defects, which may cause significantly decreased motor NCV and CMAP values that may be misinterpreted. Genetic Heterogeneity of Autosomal Dominant Intermediate CMT In addition to CMTDIB, which is caused by mutation in the DNM2 gene, other forms of dominant intermediate CMT include CMTDIA (620378), mapped to chromosome 10q24-q25; CMTDIC (608323), caused by mutation in the YARS gene (603623) on chromosome 1p35; CMTDID (607791), caused by mutation in the MPZ gene (159440) on chromosome 1q22; CMTDIE with focal segmental glomerulosclerosis (CMTDIE; 614455), caused by mutation in the INF2 gene (610982) on chromosome 14q32; CMTDIF (615185), caused by mutation in the GNB4 gene (610863) on chromosome 3q26; and CMTDIG (617882), caused by mutation in the NEFL gene (162280) on chromosome 8p21.</div>

<div class="spaceAbove">Autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) is clinically characterized by a progressive cerebellar ataxia, peripheral neuropathy, and spasticity. Disease onset of classic ARSACS is often in early childhood, leading to delayed walking because of gait unsteadiness in very young toddlers, while an increasing number of individuals with disease onset in teenage or early-adult years are now being described. Typically the ataxia is followed by lower-limb spasticity and later by peripheral neuropathy – although pronounced peripheral neuropathy has been observed as a first sign of ARSACS. Oculomotor disturbances, dysarthria, and upper-limb ataxia develop with slower progression than the other findings. Brain imaging demonstrates atrophy of the superior vermis and the cerebellar hemisphere with additional findings on MRI, such as linear hypointensities in the pons and hyperintense rims around the thalami. Many affected individuals (though not all) have yellow streaks of hypermyelinated fibers radiating from the edges of the optic disc noted on ophthalmologic exam, and thickened retinal fibers can be demonstrated by optical coherence tomography. Mild intellectual disability, hearing loss, and urinary urgency and incontinence have been reported in some individuals.</div>

<div class="spaceAbove">Congenital hypomyelinating neuropathy (CHN) is characterized clinically by onset of hypotonia at birth, areflexia, distal muscle weakness, and very slow nerve conduction velocities (often less than 10 m/s). 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 Balestrini et al., 1991), CHN is considered to result from a congenital impairment in myelin formation, whereas DSS is thought to be due to aberrant demyelination and subsequent remyelination of the peripheral nerve. There is also variation in the prognosis of patients diagnosed with CHN. In patients with CHN, Harati and Butler (1985) showed correlation of morbidity and mortality with the presence/absence of onion bulbs: patients with few onion bulbs died in early infancy, usually because of difficulty in swallowing and respiration after birth. Patients with atypical onion bulbs survived but were affected with severe motor and sensory impairment. These differences in outcome may represent genetic heterogeneity such that mutations in essential early myelin gene(s) cause a severe phenotype, whereas mutations in other, possibly later acting gene(s), such as MPZ, lead to a less severe outcome. Genetic Heterogeneity of Congenital Hypomyelinating Neuropathy See also CHN2 (618184), caused by mutation in the MPZ gene (159440) on chromosome 1q23; and CHN3 (618186), caused by mutation in the CNTNAP1 gene (602346) on chromosome 17q21.</div>

MFN2-HMSN is characterized by more severe involvement of the lower extremities than the upper extremities, distal upper-extremity involvement as the neuropathy progresses, more prominent motor deficits than sensory deficits, and normal (>42 m/s) or only slightly decreased nerve conduction velocities (NCVs). Postural tremor is common. Median onset is age 12 years in the AD form and age eight years in the AR form. The prevalence of optic atrophy is approximately 7% in the AD form and approximately 20% in the AR form.</div>

<div class="spaceAbove">Congenital hypomyelinating neuropathy-2 is an autosomal dominant neurologic disorder characterized by early-onset hypotonia, severely delayed motor development, muscle weakness with areflexia, and severely decreased nerve conduction velocities (NCV) resulting from improper myelination of axons. The severity is variable: some patients may present at birth with contractures and respiratory insufficiency, whereas others may achieve walking (summary by Warner et al., 1996). CHN shows significant phenotypic overlap with Dejerine-Sottas syndrome (DSS; 145900), which is also a neuropathy with early onset. Some classify the disorders differently, noting that CHN is characterized by hypo- or amyelination resulting from a congenital defect in myelin formation, whereas DSS has features of continuous myelin breakdown, with demyelination and remyelination (summary by Smit et al., 2008).
