MYC-N amplification study A laboratory test in which tumor or bone marrow cells are checked to see how many copies of the MYC-N gene are in the DNA. MYC-N is important for cell growth. Having more than 10 copies of the gene is called MYC-N amplification. Neuroblastoma with MYC-N amplification is more likely to spread in the body and less likely to respond to treatment. |
