Clinical Comment

Although sporadic primary neoplasms account for the majority of nervous system tumors, familial tumor syndromes are also clinically relevant. Intracranial malignancies such as meningiomas, glioblastomas, astrocytomas, medulloblastomas, ependymomas, oligodendrogliomas, craniopharyngiomas and pituitary adenomas may each be associated with one or another genetic syndrome. Therefore, the tumors that manifest with these genetic syndromes show quite different phenotypes. They may appear early in life and may be multiple as well. The respective prognosis may be better or worse if these tumors are associated with a familial syndrome such as in neurofibromatosis type 1 + 2, tuberous sclerosis complex, von Hippel-Lindau syndrome, hereditary nonpolyposis-associated colorectal carcinoma, multiple endocrine neoplasia 1 or Gorlin or Li-Fraumeni syndrome, respectively. Peripheral nerve sheath tumors include neurofibromas, schwannomas, meningiomas, vestibular schwannomas and hemangioblastomas. Often autosomal dominant inheritance patterns are observed, rarely autosomal recessive transmission. The molecular genetic diagnostic yields naturally vary widely depending on tumor entities and genetic causes. A negative DNA result does not exclude the clinical diagnosis.
