Session 8: Genetic mosaicism and clonal hematopoiesis

session overview

  • How are mosaic chromosomal alterations detected?
  • What risk factors are associated with the development and clonal expansion of mosaic chromosomal alterations?
  • Do mosaic chromosomal alterations alter disease risk (e.g., cancer)?
