Distal hereditary motor neuropathy type V, also known as DHMN-V, is a rare genetic disorder that affects the motor neurons in the peripheral nervous system. Some other commonly used terms for DHMN-V include spinal muscular atrophy, hereditary motor and sensory neuropathy type V and Charcot-Marie-Tooth disease type 2U. These different names are often used interchangeably to describe the same condition. The symptoms of DHMN-V commonly include muscle weakness and wasting in the feet and lower legs, leading to difficulties with walking and balance. While there is currently no cure for DHMN-V, early diagnosis and treatment can help to manage symptoms and improve quality of life for those living with the condition.
