What is the official name of the MYCN gene?
The official name of this gene is “v-myc avian myelocytomatosis viral oncogene neuroblastoma derived homolog.”
MYCN is the gene's official symbol. The MYCN gene is also known by other names, listed below.

What is the normal function of the MYCN gene?
The MYCN gene provides instructions for making a protein that plays an important role in the formation of tissues and organs during embryonic development. Studies in animals suggest that this protein is necessary for normal development of the limbs, heart, kidneys, nervous system, digestive system, and lungs. The MYCN protein regulates the activity of other genes by attaching (binding) to specific regions of DNA. On the basis of this action, this protein is called a transcription factor.
The MYCN gene belongs to a class of genes known as oncogenes. When mutated, oncogenes have the potential to cause normal cells to become cancerous. The MYCN gene is a member of the Myc family of oncogenes. These genes play important roles in regulating cell growth and division (proliferation) and the self-destruction of cells (apoptosis).
Does the MYCN gene share characteristics with other genes?
The MYCN gene belongs to a family of genes called bHLH (basic helix-loop-helix).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
