Subtypes include HMSNs I-VII. HMSN I and II both refer to CHARCOT-MARIE-TOOTH DISEASE. HMSN III refers to hypertrophic neuropathy of infancy, HMSN IV refers to REFSUM DISEASE, HMSN V refers to a condition marked by a hereditary motor and sensory neuropathy associated with spastic paraplegia (see SPASTIC PARAPLEGIA, HEREDITARY). HMSN VI refers to HMSN associated with an inherited optic atrophy (OPTIC ATROPHIES, HEREDITARY), and HMSN VII refers to HMSN associated with retinitis pigmentosa. 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. 356.1 is a specific code that can be used to specify a diagnosis 356.1 contains 11 index entries View the ICD-9-CM Volume 1 356.* hierarchy Alternate Terminology Charcot-Marie-Tooth disease Neuropathic muscular atrophy  Index entries containing 356.1: Atrophy, atrophic Charcôt-Marie-Tooth 356.1 muscle, muscular 728.2 neuritic 356.1 neuropathic (peroneal) (progressive) 356.1 peroneal 356.1 Charcôt-Marie-Tooth disease, paralysis, or syndrome 356.1 Disease, diseased - see also Syndrome Charcôt-Marie-Tooth 356.1 Dystrophy, dystrophia 783.9 muscular 359.1 progressive (hereditary) 359.1 Charcôt-Marie-Tooth 356.1 Marie-Charcôt-Tooth neuropathic atrophy, muscle 356.1 Neuropathy, neuropathic (see also Disorder, nerve) 355.9 hypertrophic Charcôt-Marie-Tooth 356.1 Paralysis, paralytic (complete) (incomplete) 344.9 Charcôt-Marie-Tooth type 356.1 Syndrome - see also Disease Charcôt-Marie-Tooth 356.1
