Hereditary motor and sensory neuropathies (HMSN) are a group of neuropathies which are characterized by their impact upon both afferent and efferent neural communication.

They are more common than hereditary sensory and autonomic neuropathies.

Types

In 1968, it was classified from groups I to VII:

Type	Other names	Diseases Database	OMIM
HMSN1	Charcot–Marie–Tooth disease type 1	5815	(multiple)
HMSN2	Charcot–Marie–Tooth disease type 2	2343	(multiple)
HMSN3	Dejerine–Sottas disease Charcot–Marie–Tooth disease type 3	5821	145900
HMSN4	Refsum disease	11213	266500
HMSN5	Charcot–Marie–Tooth disease with pyramidal features HMSN with pyramidal features	—	600361
HMSN6	Charcot–Marie–Tooth disease type 6 HMSN with optic atrophy	32095	601152
HMSN7	HMSN+retinitis pigmentosa	32094	—

HMSN is sometimes equated with Charcot-Marie-Tooth disease.
