- | [[http://www.uniprot.org/uniprot/DCTN1_HUMAN DCTN1_HUMAN]] Defects in DCTN1 are the cause of distal hereditary motor neuronopathy type 7B (HMN7B) [MIM:[http://omim.org/entry/607641 607641]]; also known as progressive lower motor neuron disease (PLMND). HMN7B is 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.<ref>PMID:12627231</ref><ref>PMID:16505168</ref><ref>PMID:19136952</ref><ref>PMID:19279216</ref> Defects in DCTN1 are a cause of susceptibility to amyotrophic lateral sclerosis (ALS) [MIM:[http://omim.org/entry/105400 105400]]. ALS is a neurodegenerative disorder affecting upper and lower motor neurons, and resulting in fatal paralysis. Sensory abnormalities are absent. Death usually occurs within 2 to 5 years. The etiology is likely to be multifactorial, involving both genetic and environmental factors.<ref>PMID:15326253</ref><ref>PMID:16240349</ref> Defects in DCTN1 are the cause of Perry syndrome (PERRYS) [MIM:[http://omim.org/entry/168605 168605]]; also called parkinsonism with alveolar hypoventilation and mental depression. Perry syndrome is a neuropsychiatric disorder characterized by mental depression not responsive to antidepressant drugs or electroconvulsive therapy, sleep disturbances, exhaustion and marked weight loss. Parkinsonism develops later and respiratory failure occurred terminally.<ref>PMID:19136952</ref> | + | <StructureSection load='3tq7' size='340' side='right'caption='[[3tq7]], [[Resolution|resolution]] 2.30Å' scene=''> |
