Flow chart of informative loci identification and marker validation. This work can be divided into two phases: the computational identification of informative MST loci phase and the marker validation phase. Phase 1: 488 non-small cell lung germline cancer samples from the TCGA and 390 germline non-cancer control samples from the 1000 genomes project we analyzed. This analysis yielded 119 MST loci that have significant genotype difference in the cancer and control samples. Phase 2: this set of 119 markers, along with 144 MST markers that were computationally found to be significant for others cancers, were pooled into a target enrichment kit which was used to sequence at high depth a total of 30 lung cancer samples and 89 non-cancer control samples. Of these 263 (119+144) MST markers, 21 were found to consistently differentiate lung cancer and control samples.
