The RMSE over all subtypes using the proposed prediction model was lowest for genes coding for transcription factors, GTPases, and nucleic-acid binding proteins: TRA2B, HNRNPK, RAB5B, SEC11A, SF3A1, SRP14, CDC42, and NRF showed the lowest RMSE over all breast cancer subtypes. The gene discussed is RAB5B; the disease is breast cancer.
