In a study which predicted papillary thyroid carcinomas as BRAF or RAS mutated, Tsou et al. found that mRNA-derived expression patterns correlated with the deep learning model’s predictions, enabling the classification of tumours harbouring neither BRAF nor RAS mutations to be classified as BRAF- or RAS-like [40]. Here, BRAF is linked to thyroid gland papillary carcinoma.
