Is a hereditary brain tumor

Hereditary cancers

The following clinical features and peculiarities can provide important clues for the presence of a hereditary tumor disease:

  • Family accumulation
  • Early age of onset
  • Various primary tumors (tumor spectrum)
  • Multiple tumors appearing in one person (at the same time or one after the other)
  • Bilateral appearance of tumors in a person
  • Associated malformations

If the indication for a molecular genetic diagnosis has been made, molecular genetic examinations for the hereditary tumor diseases listed in the following table can be carried out at the IMD:
