Symptoms may become apparent during childhood, adolescence, early adulthood or later in adult life. In some individuals with NF2, additional abnormalities may be present. These may include clouding of the lenses of the eyes juvenile posterior subcapsular opacitiesprogressive visual impairment, or an increased risk of developing certain tumors of the lining of the brain meningiomas and spinal cord central nervous system.
What are the neurofibromatoses? What is NF1? What are the signs and symptoms of NF1?
Neurofibromatosis 1 NF1also called von Recklinghausen's disease, is a genetic disorder characterized by the development of multiple noncancerous benign tumors of nerves and skin neurofibromas and areas of abnormal skin color pigmentation. Areas of abnormal skin pigmentation typically include pale tan or light brown discolorations cafe-au-lait spotsfreckling in atypical locations such as under the arms axillary region or in the groin inguinal region. Such abnormalities of skin pigmentation are often evident by one year of age and tend to increase in size and number over time.
Patients with neurofibromatosis 1 NF1NF2, and schwannomatosis are at risk for multiple nerve sheath tumors and premature mortality. Traditional magnetic resonance imaging MRI has limited ability to assess disease burden accurately. The aim of this study was to establish an international cohort of patients with quantified whole-body internal tumor burden and to correlate tumor burden with clinical features of disease.
Neurofibromatosis Type 1 NF1 is a common genetic neurocutaneous disease, with an autosomal dominant inheritance mode. Quality of life has been shown impaired in NF1, due to severe complications, cosmetic features, and uncertainty about the disorder. This study sought to develop a self-administered questionnaire in French to assess the burden of NF1 BoNthen translate and linguistically and cross-culturally validate it into American English, standardized methodology applied, as outlined in the report.
