Neurofibromatosis (NF) dey refer to a group of three distinct genetic conditions insyd wich tumors grow insyd de nervous system.[1] De tumors be non-cancerous (benign) wey often dey involve de skin anaa surrounding bone.[1] Although symptoms often be mild, each condition dey present differently. Neurofibromatosis type I (NF1) typically be characterized by café au lait spots (light-brown flat patches of skin), neurofibromas (small bumps insyd anaa under de skin), scoliosis (side-way curvature of de back), den headaches.[2] Neurofibromatosis type II (NF2), on de oda hand, fi present plus early-onset hearing loss, cataracts, tinnitus, difficulty walking anaa maintaining balance, den muscle atrophy.[2] Dem dey bell de third type schwannomatosis den often dey present insyd early adulthood plus widespread pain, numbness, anaa tingling secof nerve compression.[3]

De cause be a genetic mutation insyd certain oncogenes.[1] Dese fi be inherited, anaa insyd about half of cases spontaneously occur during early development.[1] Different mutations result insyd de three types of NF.[4] Neurofibromatosis dey arise from de supporting cells of de nervous system rada dan de neurons demaselves.[1] Insyd NF1, de tumors be neurofibromas (tumors of de peripheral nerves), while insyd NF2 den schwannomatosis tumors of Schwann cells be more common.[1] Diagnosis typically be based on symptoms, examination, medical imaging, den biopsy.[5][6] Genetic testing rarely fi be done to support de diagnosis.[2]

Der be no known prevention anaa cure.[1][2] Surgery fi be done to remove tumors wey dey cause problems anaa e cam be cancerous.[1] Radiation den chemotherapy sanso fi be used if cancer occur.[1] A cochlear implant anaa auditory brainstem implant fi help sam wey get hearing loss secof de condition.[1]

Insyd de United States, about 1 insyd 3,500 people get NF1 den 1 insyd 25,000 get NF2.[1] Males den females be affected equally often.[2] Insyd NF1, symptoms often be present at birth anaa develop before 10 years of age.[1] While de condition typically dey worsen plus time, chaw people plus NF1 get a normal life expectancy.[1] Insyd NF2, symptoms no fi cam be apparent til early adulthood.[1] NF2 dey increase de risk of early death.[1] Descriptions of de condition occur as far back as de 1st century.[7] E be formally described by Friedrich Daniel von Recklinghausen insyd 1882, after whom na dem previously name "von Recklinghausen's disease".[4]
