Distal Hereditary Motor Neuropathy
Definition
Distal hereditary motor neuropathy (dHMN) is a group of rare genetic disorders characterized by progressive degeneration of motor neurons in the peripheral nervous system, leading to muscle weakness and atrophy primarily in the distal limbs. The severity and age of onset can vary widely among individuals, and the condition may be inherited in an autosomal dominant, autosomal recessive, or X-linked manner.
