Abstract Neurofibromatosis 1 (NF-1) (von Rekhlinghausen disease) and neurofibromatosis 2 (NF-2) (bilateral acoustic neurofibromatosis) have been recently recognized to be distinct disorders through genetic linkages. NF-1 is much more common than NF-2, accounting for greater than 90% of all cases of neurofibromatosis. All individuals inherit two copies of each gene.
