First, gene copy number analysis of LIMD1 and a number of other well‐characterised tumour suppressor genes in lung adenocarcinoma (LUAD) and squamous cell carcinoma (LUSC) cohorts (n = 512 and n = 498, respectively) demonstrated that single (shallow) or bi‐allele (Ghosh et al, 2008) deletion of the LIMD1 gene occurred in 47.1% (LUAD) and 85.4% of patients (LUSC; Figs 6D and EV5D). This evidence concerns the gene LIMD1 and lung adenocarcinoma.
