What is the genetic disorder characterized by multiple benign fibrous tumors in the nervous system?

Neurofibromatosis is characterized by the development of multiple benign tumors called neurofibromas, primarily affecting the nervous system. This genetic disorder is usually inherited in an autosomal dominant pattern and can lead to various health challenges, including skin changes, skeletal abnormalities, and potential complications in neurological function. The presence of café-au-lait spots is also a hallmark feature of this condition, aiding in its diagnosis.

In contrast, spina bifida occulta refers to a failure of bony encasement of the spinal cord and is not associated with tumors. Osteogenesis imperfecta is primarily a connective tissue disorder characterized by brittle bones due to collagen defects, rather than tumor formation. Turner syndrome is a chromosomal disorder that affects females, resulting from a missing or incomplete X chromosome and is not linked to neuromas or tumors. Thus, the defining trait of benign fibrous tumors in the nervous system makes neurofibromatosis the correct response.
