At the genomic level, specific biomarkers such as EGFR (Blakely et al., 2017) and KRAS (Arbour et al., 2018) exist for lung cancer, TP53 (Long et al., 2019) and LRP1B (Wang et al., 2019) for liver cancer, and BRAF (Ribas et al., 2019) and TP53 (Xiao et al., 2018) for skin melanoma. The gene discussed is TP53; the disease is cutaneous melanoma.
