Indeed, CNN models applied to routine H&E‐stained tumour sections have been described for the prediction of biomarkers such as mutations in KRAS [23, 34], BRAF [33, 34], TP53 [23, 34, 36, 37], microsatellite instability [34], and tumour mutational burden (TMB) [35]. The gene discussed is KRAS; the disease is neoplasm.
