Summaries for Neuronopathy, Distal Hereditary Motor, Type Viib

UniProtKB/Swiss-Prot : 76 Neuronopathy, distal hereditary motor, 7B: A neuromuscular disorder. Distal hereditary motor neuronopathies constitute a heterogeneous group of neuromuscular disorders caused by selective degeneration of motor neurons in the anterior horn of the spinal cord, without sensory deficit in the posterior horn. The overall clinical picture consists of a classical distal muscular atrophy syndrome in the legs without clinical sensory loss. The disease starts with weakness and wasting of distal muscles of the anterior tibial and peroneal compartments of the legs. Later on, weakness and atrophy may expand to the proximal muscles of the lower limbs and/or to the distal upper limbs.

MalaCards based summary : Neuronopathy, Distal Hereditary Motor, Type Viib, also known as neuropathy, distal hereditary motor, type viib, is related to perry syndrome and spinal muscular atrophy, jokela type, and has symptoms including facial paresis An important gene associated with Neuronopathy, Distal Hereditary Motor, Type Viib is DCTN1 (Dynactin Subunit 1). Affiliated tissues include spinal cord, and related phenotypes are facial palsy and hand muscle atrophy
