Definition

A family of genes that makes proteins involved in many cell functions, including cell growth, cell maturation, and cell death. Genetic changes in the DNA sequence of the MYC genes have been found in many types of cancer, including leukemia and lymphoma. These changes may cause cancer cells to grow and spread in the body. Members of the MYC gene family include C-MYC, L-MYC, and N-MYC.
