Summaries for Charcot-Marie-Tooth Disease, X-Linked Dominant, 6

UniProtKB/Swiss-Prot : 75 Charcot-Marie-Tooth disease, X-linked dominant, 6: A 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 characterized by severely reduced motor nerve conduction velocities (NCVs) (less than 38m/s) and segmental demyelination and remyelination, and primary peripheral axonal neuropathies characterized by normal or mildly reduced NCVs and chronic axonal degeneration and regeneration on nerve biopsy.

MalaCards based summary : Charcot-Marie-Tooth Disease, X-Linked Dominant, 6, also known as cmtx6, is related to charcot-marie-tooth disease and tooth disease, and has symptoms including tremor of hands An important gene associated with Charcot-Marie-Tooth Disease, X-Linked Dominant, 6 is PDK3 (Pyruvate Dehydrogenase Kinase 3). Affiliated tissues include eye, and related phenotypes are sensorineural hearing impairment and pes cavus

Disease Ontology : 12 A Charcot-Marie-Tooth disease X-linked that has material basis in mutation in the PDK3 gene on chromosome Xp22.
