NF Sentence Examples
Neurofibromatosis (NF) is a genetic disease in which multiple soft tumors (neurofibromas) develop under the skin and throughout the nervous system.
In both types of NF, a genetic defect causes these neural crest cells to develop abnormally, resulting in numerous tumors and malformations of the nerves, bones, and skin.
However, a family pattern of NF is only evident for about half of all cases of NF.
The other cases of NF occur due to a spontaneous mutation (a permanent change in the structure of a specific gene).
The chance of a person with NF passing on the NF gene to a child is 50 percent.
