Summary

Autosomal recessive distal hereditary motor neuronopathy-2 (HMNR2) is a neuromuscular disorder characterized by onset of distal muscle weakness and wasting affecting the lower and upper limbs in the first decade; there is no sensory involvement (summary by Li et al., 2015). For a general phenotypic description and a discussion of genetic heterogeneity of autosomal recessive HMN, see HMNR1 (604320). [from OMIM]
