Thirteen tumors had two non-silent MAP3K1 mutations (biallelic loss), and most of the mutations are highly deleterious (nonsense, frameshift, etc.) suggesting that this gene may act as a tumor suppressor.

Two genes were already recurrently mutated in the 7 WGS cases: RUNX1, a known myeloid tumor suppressor, and UMODL1, for which mutations were recently reported in multiple myeloma and ovarian cancer.

Additionally, alterations of subcellular localization through aberrant splicing or genetic mutations also provide ways to inactivate tumor suppressor genes (50).

Moreover, many human tumors have highly abnormal numbers of chromosomes (that is, they are aneuploid), with initial chromosomal loss participating in the early steps of the transformation cascade in inherited cancers caused by heterozygous mutation in tumor suppressor genes and the more widespread aneuploidy characteristic of advance tumors thought to drive acquisition of malignant growth properties.??
