Entrez Gene summary for MFN2 Gene:
This gene encodes a mitochondrial membrane protein that participates in mitochondrial fusion and contributes to
the maintenance and operation of the mitochondrial network. This protein is involved in the regulation of
vascular smooth muscle cell proliferation, and it may play a role in the pathophysiology of obesity. Mutations in
this gene cause Charcot-Marie-Tooth disease type 2A2, and hereditary motor and sensory neuropathy VI, which are
both disorders of the peripheral nervous system. Defects in this gene have also been associated with early-onset
stroke. Two transcript variants encoding the same protein have been identified. (provided by RefSeq, Jul 2008)

GeneCards Summary for MFN2 Gene:
MFN2 (mitofusin 2) is a protein-coding gene. Diseases associated with MFN2 include hereditary motor and sensory neuropathy vi, and charcot-marie-tooth disease with pyramidal features, autosomal dominant. GO annotations related to this gene include GTP binding and ubiquitin protein ligase binding. An important paralog of this gene is MFN1.

UniProtKB/Swiss-Prot: MFN2_HUMAN, O95140
Function: Essential transmembrane GTPase, which mediates mitochondrial fusion. Fusion of mitochondria occurs in
many cell types and constitutes an important step in mitochondria morphology, which is balanced between fusion
and fission. MFN2 acts independently of the cytoskeleton. It therefore plays a central role in mitochondrial
metabolism and may be associated with obesity and/or apoptosis processes. Overexpression induces the formation of
mitochondrial networks. Plays an important role in the regulation of vascular smooth muscle cell proliferation.
Involved in the clearance of damaged mitochondria via selective autophagy (mitophagy). Is required for PARK2
recruitment to dysfunctional mitochondria

  • Charcot-Marie-Tooth disease 2A2 (CMT2A2) [MIM:609260]: An axonal 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). Neuropathies of the CMT2 group are characterized by signs of axonal degeneration in the absence of
    obvious myelin alterations, normal or slightly reduced nerve conduction velocities, and progressive distal muscle
    weakness and atrophy. Nerve conduction velocities are normal or slightly reduced. Note=The disease is caused by
    mutations affecting the gene represented in this entry
  • Charcot-Marie-Tooth disease 6 (CMT6) [MIM:601152]: A form of Charcot-Marie-Tooth disease characterized by
    the association of axonal peripheral neuropathy with optic atrophy. Charcot-Marie-Tooth disease is 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. It is classified in two main groups on the basis of
    electrophysiologic properties and histopathology: primary peripheral demyelinating neuropathies and primary
    peripheral axonal neuropathies. Peripheral axonal neuropathies are characterized by signs of axonal regeneration
    in the absence of obvious myelin alterations, normal or slightly reduced nerve conduction velocities, and
    progressive distal muscle weakness and atrophy. Nerve conduction velocities are normal or slightly reduced.
