From analysis of the 820 human breast tumor datasets with clear genomic DNA sequences, we identified 136 (16.6%) tumors with wild-type TP53 and PTEN genes, 345 (42.1%) PPAPA tumors, 95 (11.6%) TP53I tumors, and 244 (29.7%) PPAPA/TP53I tumors. The gene discussed is TP53; the disease is breast neoplasm.
