Summaries for Neuromyotonia and Axonal Neuropathy, Autosomal Recessive

NIH Rare Diseases : 53 The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.Orpha Number: 324442Disease definitionAutosomal recessive axonal neuropathy with neuromyotonia is a rare peripheral neuropathy characterized by slowly progressive axonal, motor greater than sensory polyneuropathy combined with neuromytonia (including spontaneous muscular activity at rest (myokymia), impaired muscle relaxation (pseudomyotonia), and contractures of hands and feet) and neuromyotonic or myokymic discharges on needle EMG. It presents with distal lower limb weakness with gait impairment, muscle stiffness, fasciculations and cramps in hands and legs worsened by cold, decreased to absent tendon reflexes, intrinsic hand muscle atrophy and, variably, mild distal sensory impairment.Visit the Orphanet disease page for more resources.

MalaCards based summary : Neuromyotonia and Axonal Neuropathy, Autosomal Recessive, also known as gamstorp-wohlfart syndrome, is related to axonal neuropathy and neuropathy, and has symptoms including muscle weakness, myalgia and myokymia. An important gene associated with Neuromyotonia and Axonal Neuropathy, Autosomal Recessive is HINT1 (Histidine Triad Nucleotide Binding Protein 1). Affiliated tissues include brain, spinal cord and tongue, and related phenotypes are hyperhidrosis and elevated serum creatine phosphokinase

Disease Ontology : 12 A syndrome characterized by progressive weakness and atrophy of muscles in feet, legs and hands. In some patients the syndrome also causes decreased sensitivity to touch, heat or cold, particularly in the lower arms or legs.

Genetics Home Reference : 25 Autosomal recessive axonal neuropathy with neuromyotonia is a disorder that affects the peripheral nerves. Peripheral nerves connect the brain and spinal cord to muscles and to sensory cells that detect sensations such as touch, pain, heat, and sound.

OMIM : 57 NMAN is an autosomal recessive neurologic disorder characterized by onset in the first or second decade of a peripheral axonal neuropathy predominantly affecting motor more than sensory nerves. The axonal neuropathy is reminiscent of Charcot-Marie-Tooth disease type 2 (see, e.g., CMT2A1, 118210) and distal hereditary motor neuropathy (see, e.g., HMN1, 182960). Individuals with NMAN also have delayed muscle relaxation and action myotonia associated with neuromyotonic discharges on needle EMG resulting from hyperexcitability of the peripheral nerves (summary by Zimon et al., 2012). (137200)

UniProtKB/Swiss-Prot : 75 Neuromyotonia and axonal neuropathy, autosomal recessive: An autosomal recessive neurologic disorder characterized by onset in the first or second decade of a peripheral axonal neuropathy predominantly affecting motor more than sensory nerves.
