MTMR3 was a statistically significant discriminator of all four groups (except non-metastatic from metastatic): non-metastatic from fibroadenoma (cutoff > 4.18), non-metastatic from control (cutoff > 1.0), metastatic from fibroadenoma (cutoff > 1.0), and fibroadenoma from control (cutoff > 1.0). The gene discussed is MTMR3; the disease is Fibroadenoma.
