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

UniProtKB/Swiss-Prot : 76 Charcot-Marie-Tooth disease 1C: 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 1c, also known as charcot-marie-tooth disease, type 1c, is related to charcot-marie-tooth disease and deafness and neuropathy. An important gene associated with Charcot-Marie-Tooth Disease, Demyelinating, Type 1c is LITAF (Lipopolysaccharide Induced TNF Factor), and among its related pathways/superpathways is Neural Crest Differentiation. Related phenotypes are pes cavus and decreased motor nerve conduction velocity

Disease Ontology : 12 A Charcot-Marie-Tooth disease type 1 that has material basis in heterozygous mutation in the LITAF gene on chromosome 16p13.

OMIM : 58 For a phenotypic description and a discussion of genetic heterogeneity of autosomal dominant Charcot-Marie-Tooth disease type 1, see CMT1B (118200). (601098)
