Neurofibromatosis (NF) refers to a number of inherited conditions that are clinically and genetically distinct and carry a high risk of tumor formation, particularly in the brain.[1] Neurofibromatosis is an autosomal dominant disorder, which means only one copy of the affected gene is needed for the disorder to develop. Therefore, if only one parent has neurofibromatosis, his or her children have a 50% chance of developing the condition as well (it is rarely the case that one person has the mutated gene twice, which would imply a 100% chance of their children developing NF). The severity in affected individuals can vary; this may be due to variable expressivity. Approximately half of cases are due to de novo mutations and no other affected family members are seen. It affects males and females equally. In addition, some individuals may have mosaic NF, in which some but not all cells of the body carry the mutation. The neurofibromatoses are as follows:

Conditions which may be confused with NF-1 but which are not considered NF include:

The Neurofibromatoses are considered as RASopathies and as members of the neurocutaneous syndromes (phakomatoses).[2] In addition to the types of neurofibromatosis, the phakomatoses also include tuberous sclerosis, Sturge-Weber syndrome, and von Hippel-Lindau disease. This grouping is an artifact of an earlier time in medicine, before the distinct genetic basis of each of these diseases was understood.


Recently, non-profit and charitable organizations have started to bring awareness and education about Neurofibromatoses to mainstream media in order to better connect those afflicted with helpful resources to lead more productive and satisfying lives.[3] Personalities with the condition, such as Reggie Bibbs, are becoming notable public figures around which others can rally to gain motivation and support.[4]
