Neuronopathy, Distal Hereditary Motor, Type Vb; Hmn5b

Description

Distal hereditary motor neuronopathy type VB is an autosomal dominant neurologic disorder characterized by onset in the first or second decade of distal muscle weakness and atrophy, primarily affecting the intrinsic hand muscles, but also affecting the lower legs, resulting in abnormal gait and pes cavus (summary by Beetz et al., 2012).For a general phenotypic description and a discussion of genetic heterogeneity of distal HMN (dHMN), see HMN type I (HMN1 ).
