Von Recklinghausen Disease (NF I)


Neurofibromatosis 1 (NF1), also known as von Recklinghausen Disease, is an autosomal dominant cancer syndrome that causes tumors to form in the brain, spinal cord, and nerves.

The disease is caused by a mutation of NF1 on chromosome 17, and if inherited, the disease is almost certain to appear (complete penetrance), although individual symptoms may vary (variable expressivity). Clinical features include cafe-au-lait spots, cutaneous neurofibromas, optic gliomas, Lisch nodules of the iris, and pheochromocytomas (presenting as episodic hypertension and headaches).
