Summaries for Charcot-Marie-Tooth Disease, Demyelinating, Type 4f

UniProtKB/Swiss-Prot : 75 Charcot-Marie-Tooth disease 4F: 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. CMT4F is characterized by distal sensory impairment and distal muscle weakness and atrophy affecting the lower more than the upper limbs. The age at onset is variable and can range from childhood to adult years. When the onset is in infancy, the phenotype is characterized as Dejerine-Sottas syndrome.

MalaCards based summary : Charcot-Marie-Tooth Disease, Demyelinating, Type 4f, also known as charcot-marie-tooth disease type 4f, is related to hypertrophic neuropathy of dejerine-sottas and neuropathy, congenital hypomyelinating or amyelinating, autosomal recessive, and has symptoms including ataxia, sensory An important gene associated with Charcot-Marie-Tooth Disease, Demyelinating, Type 4f is PRX (Periaxin). Affiliated tissues include skeletal muscle, and related phenotypes are scoliosis and skeletal muscle atrophy

OMIM : 57 Charcot-Marie-Tooth disease type 4F is an autosomal recessive demyelinating neuropathy characterized by distal sensory impairment and distal muscle weakness and atrophy affecting the lower more than the upper limbs. Nerve conduction velocities are decreased and sural nerve biopsy shows loss of myelinated fibers. The age at onset is variable and can range from childhood to adult years. When the onset is in infancy, the phenotype is characterized as Dejerine-Sottas syndrome (DSS; 145900). For a phenotypic description and a discussion of genetic heterogeneity of autosomal recessive demyelinating Charcot-Marie-Tooth disease, see CMT4A (214400). (614895)
