Neurofibromatosis is a rare genetic Disorder in the nervous system. In this case, benign tumors grow in the nerves and in other parts of the body which affect the growth and development of nerve cell tissue. Sometimes people with this disorder affected profoundly whereas some could barely notice the neurological problems. In this disorder is a group of three disorder in which the tumors grow in the nervous system. The three types are neurofibromatosis type 1 (NF1), type 2 (NF2) neurofibromatosis and Schwannomatosis. Neurofibromas that occur on or under the skin, sometimes even deep within the body; these are benign (harmless) tumors; however, in rare cases, they can turn malignant or cancerous.
Causes:
Neurofibromatosis is often inherited (passed on by family individuals through our genes), but around 50% of individuals recently analyzed with the disorder have no family history of the condition, which can emerge spontaneously through a mutation in the genes. Once this change has taken place, the mutant gene can be passed on to future eras.

Symptoms:
<>In NF1 side effects include light brown spots on the skin, freckles within the armpit and crotch, small bumps inside nerves, and scoliosis.
<>Tiny growths in the iris (colored area) of the eye; these are called Lisch nodules and usually do not affect eyesight.
<>Bone deformities, including a twisted spine (scoliosis) or bowed legs
Tumors along the optic nerve, which may cause eyesight problems

<>In NF2 there may be hearing loss, cataracts at a youthful age, balance issues, flesh-colored skin flaps, and muscle wasting.
<>The tumors are generally non-cancerous.

<>In schwannomatosis isn't well-understood it is estimated that 85 percent of cases have no known cause (“spontaneous”) and 15 percent are acquired.
Diagnosis:
<>Neurofibromatosis is diagnosed using a number of tests, including:
<>Physical examination
<>Medical history
<>Family history
<>X-rays
<>Computerized tomography (CT) scans
<>Magnetic resonance imaging (MRI)
<>Biopsy of neurofibromas
<>Eye tests
<>Tests for particular symptoms, such as hearing or balance tests
