- Ewing sarcoma (HP:0012254): A malignant tumor of the bone which always arises in the medullary tissue, occurring more often in cylindrical bones. Evidence: TAS. (OMIM:612219)
- Typified by somatic mosaicism (HP:0001442): Description of conditions in which affected individuals typically display somatic mosaicism, i.e., genetically distinct populations of somatic cells in a given organism caused by DNA mutations, epigenetic alterations of DNA, chromosomal abnormalities or the spontaneous reversion of inherited mutations. In many conditions typified by somatic mosaicism, constitutive mutation is lethal and cases are exclusively or predominantly mosaic. Evidence: TAS. (OMIM:612219)
