Summaries for Charcot-Marie-Tooth Disease, Demyelinating, Type 1b

UniProtKB/Swiss-Prot : 76 Charcot-Marie-Tooth disease 1B: A dominant 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.

MalaCards based summary : Charcot-Marie-Tooth Disease, Demyelinating, Type 1b, also known as charcot-marie-tooth disease type 1b, is related to roussy-levy hereditary areflexic dystasia and charcot-marie-tooth disease, x-linked dominant, 1, and has symptoms including seizures, tremor and back pain. An important gene associated with Charcot-Marie-Tooth Disease, Demyelinating, Type 1b is MPZ (Myelin Protein Zero), and among its related pathways/superpathways is Neural Crest Differentiation. The drugs HIV Protease Inhibitors and Matrix Metalloproteinase Inhibitors have been mentioned in the context of this disorder. Affiliated tissues include skeletal muscle, and related phenotypes are muscle weakness and scoliosis

Disease Ontology : 12 A Charcot-Marie-Tooth disease type 1 that has material basis in heterozygous mutation in the gene encoding myelin protein zero (MPZ).

OMIM : 58 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. (118200)
