A hereditary motor and sensory neuropathy transmitted most often as an autosomal dominant trait and characterized by progressive distal wasting and loss of reflexes in the muscles of the legs (and occasionally involving the arms). Onset is usually in the second to fourth decade of life. This condition has been divided into two subtypes, hereditary motor and sensory neuropathy (HMSN) types I and II. HMSN I is associated with abnormal nerve conduction velocities and nerve hypertrophy, features not seen in HMSN II. (Adams et al., Principles of Neurology, 6th ed, p1343)

Hypoglossal Neuropathy
- twelfth cranial (hypoglossal) nuclei. fascicles are located in medulla, exits via hypoglossal foramen innervates muscles tongue. Lower brain stem diseases, including ischemia MOTOR NEURON affect nuclei fascicles. nerve may also be injured by diseases of the posterior fossa or skull base. Clinical manifestations include unilateral musculature and lingual dysarthria, with deviation tongue towards side weakness upon attempted protrusion.
