Label	Id	Description
Neuromuscular Junction Diseases	D020511	[Conditions characterized by impaired transmission of impulses at the NEUROMUSCULAR JUNCTION. This may result from disorders that affect receptor function, pre- or postsynaptic membrane function, or ACETYLCHOLINESTERASE activity. The majority of diseases in this category are associated with autoimmune, toxic, or inherited conditions.]
Neuromuscular Manifestations	D020879	[Signs and symptoms associated with diseases of the muscle, neuromuscular junction, or peripheral nerves.]
Neuromyelitis Optica	D009471	[A syndrome characterized by acute OPTIC NEURITIS; MYELITIS, TRANSVERSE; demyelinating and/or necrotizing lesions in the OPTIC NERVES and SPINAL CORD; and presence of specific autoantibodies to AQUAPORIN 4.]
Neuronal Ceroid-Lipofuscinoses	D009472	[A group of severe neurodegenerative diseases characterized by intracellular accumulation of autofluorescent wax-like lipid materials (CEROID; LIPOFUSCIN) in neurons. There are several subtypes based on mutations of the various genes, time of disease onset, and severity of the neurological defects such as progressive DEMENTIA; SEIZURES; and visual failure., This type is caused by mutation in the CLN2 gene encoding tripeptidyl-peptidase I, a lysosomal serine protease., This type is caused by mutation in the CLN3 gene encoding a lysosomal integral membrane protein (Battenin)., This type is caused by mutation in the gene (CLN1or PPT1) encoding palmitoyl-protein thioesterase (THIOLESTER HYDROLASES), an enzyme involved in catabolism of lipid-modified proteins.]
Neuroschistosomiasis	D020818	[SCHISTOSOMIASIS of the brain, spinal cord, or meninges caused by infections with trematodes of the genus SCHISTOSOMA (primarily SCHISTOSOMA JAPONICUM; SCHISTOSOMA MANSONI; and SCHISTOSOMA HAEMATOBIUM in humans). S. japonicum infections of the nervous system may cause an acute meningoencephalitis or a chronic encephalopathy. S. mansoni and S. haematobium nervous system infections are associated with acute transverse myelitis involving the lower portions of the spinal cord. (From Joynt, Clinical Neurology, 1998, Ch27, pp61-2)]
Neurosyphilis	D009494	[Infections of the central nervous system caused by TREPONEMA PALLIDUM which present with a variety of clinical syndromes. The initial phase of infection usually causes a mild or asymptomatic meningeal reaction. The meningovascular form may present acutely as BRAIN INFARCTION. The infection may also remain subclinical for several years. Late syndromes include general paresis; TABES DORSALIS; meningeal syphilis; syphilitic OPTIC ATROPHY; and spinal syphilis. General paresis is characterized by progressive DEMENTIA; DYSARTHRIA; TREMOR; MYOCLONUS; SEIZURES; and Argyll-Robertson pupils. (Adams et al., Principles of Neurology, 6th ed, pp722-8)]
Neurothekeoma	D018321	[A benign myxoma of cutaneous nerve sheath origin. Theke is from the Greek theke, sheath. (From Stedman, 25th ed)]
Neurotoxicity Syndromes	D020258	[Neurologic disorders caused by exposure to toxic substances through ingestion, injection, cutaneous application, or other method. This includes conditions caused by biologic, chemical, and pharmaceutical agents.]
Neutropenia	D009503	[A decrease in the number of NEUTROPHILS found in the blood.]
Nevi and Melanomas	D018326	[A collective term for the various types of nevi and melanomas.]
Nevus	D009506	[A circumscribed stable malformation of the skin and occasionally of the oral mucosa, which is not due to external causes and therefore presumed to be of hereditary origin.]
Nevus of Ota	D009507	[A macular lesion on the side of the FACE, involving the CONJUNCTIVA and EYELIDS, as well as the adjacent facial skin, SCLERA; OCULOMOTOR MUSCLES; and PERIOSTEUM. Histological features vary from those of a MONGOLIAN SPOT to those of a BLUE NEVUS.]
Nevus, Blue	D018329	[Usually a benign tumor, that commonly presents as a solitary blue nodule with spindled MELANOCYTES covered by smooth SKIN. Several variants have been identified, one variant being malignant. The blue color is caused by large, densely packed melanocytes deep in the DERMIS of the nevus. In CHILDREN, they usually occur on the BUTTOCKS and LUMBOSACRAL REGION and are referred to as cellular blue nevi. Malignant blue nevi are more commonly found on the SCALP.]
Nevus, Epithelioid and Spindle Cell	D018332	[A benign compound nevus occurring most often in children before puberty, composed of spindle and epithelioid cells located mainly in the dermis, sometimes in association with large atypical cells and multinucleate cells, and having a close histopathological resemblance to malignant melanoma. The tumor presents as a smooth to slightly scaly, round to oval, raised, firm papule or nodule, ranging in color from pink-tan to purplish red, often with surface telangiectasia. (Dorland, 27th ed)]
Nevus, Halo	D055882	[A benign skin lesion characterized by a zone of depigmentation surrounding the nevus.]
Nevus, Intradermal	D018330	[A nevus in which nests of melanocytes are found in the dermis, but not at the epidermal-dermal junction. Benign pigmented nevi in adults are most commonly intradermal. (Stedman, 25th ed)]
Nevus, Pigmented	D009508	[A nevus containing melanin. The term is usually restricted to nevocytic nevi (round or oval collections of melanin-containing nevus cells occurring at the dermoepidermal junction of the skin or in the dermis proper) or moles, but may be applied to other pigmented nevi.]
Nevus, Sebaceous of Jadassohn	D054000	[A syndrome characterized by lesions occurring on the face, scalp, or neck which consist of congenital hypoplastic malformations of cutaneous structures and which over time undergo verrucous hyperplasia. Additionally it is associated with neurological symptoms and skeletal, ophthalmological, urogenital, and cardiovascular abnormalities.]
Nevus, Spindle Cell	D018331	[A form of pigmented nevus showing intense melanocytic activity around the dermo-epidermal junction. Large numbers of spindle-shaped melanocytes proliferate downward toward the dermis and usually a large amount of pigment is present. It was first described in 1976 and the bulk of patients reported have been young females with the lesions presenting on the thighs. (From Rook et al., Textbook of Dermatology, 4th ed, 1992, p185)]
Newcastle Disease	D009521	[An acute febrile, contagious, viral disease of birds caused by an AVULAVIRUS called NEWCASTLE DISEASE VIRUS. It is characterized by respiratory and nervous symptoms in fowl and is transmissible to man causing a severe, but transient conjunctivitis.]
