Importantly, adenocarcinomas with UIP showed higher frequencies of invasive mucinous-predominant subtype (29.5% vs. 3.9%) and KRAS mutations (30.2% vs. 8.5%) while EGFR mutations were much less prevalent (2.3% vs. 45.6%) [58]. The gene discussed is KRAS; the disease is idiopathic pulmonary fibrosis.
