Inherited Neuropathies

Abstract

AbstractThe inherited neuropathies are a common and heterogeneous group of slowly progressive disorders affecting motor, sensory, and autonomic nerves. These hereditary conditions can be confined to the peripheral nervous system, termed the primary hereditary neuropathies, or can occur as part of a multisystem disease. Identification of systemic involvement is necessary to distinguish the primary and secondary hereditary neuropathies to prevent the misdiagnosis of potentially treatable entities. Recent genetic and technological advances have dramatically improved our understanding of the underlying pathophysiology of these inherited neuropathies and hence provide the correct milieu for the future development of disease-modifying therapies. This review provides clinical, neurophysiological, genetic, pathophysiological, and treatment insights into the primary inherited neuropathies, and those associated with multisystem diseases, including porphyria and mitochondrial disorders.
