Summaries for Neuronopathy, Distal Hereditary Motor, Type Iid

OMIM : 57 Distal hereditary motor neuronopathy type IID is an autosomal dominant neurologic disorder characterized by onset of slowly progressive distal lower limb weakness and atrophy between the second and fourth decades of life. Weakness usually begins in the calf muscles and later involves more proximal muscles. The severity is variable, and some patients have difficulty walking or running. Most also have upper limb involvement, particularly of the triceps and intrinsic hand muscles. Some patients may lose independent ambulation later in the disease course. Sensory impairment is typically not present, and cognition and bulbar function are normal (summary by Sumner et al., 2013). For a general phenotypic description and a discussion of genetic heterogeneity of distal HMN (dHMN), see HMN type I (HMN1; 182960). (615575)

MalaCards based summary : Neuronopathy, Distal Hereditary Motor, Type Iid, is also known as distal hereditary motor neuronopathy 2d, and has symptoms including muscular fasciculation and muscle cramp. An important gene associated with Neuronopathy, Distal Hereditary Motor, Type Iid is FBXO38 (F-Box Protein 38). Related phenotypes are pes cavus and decreased motor nerve conduction velocity
