Sequencing Study in COPD cases and controls

Since smokers with COPD have a higher risk of developing lung cancer than those without, we hypothesized that they carry more mutations in affected tissue. We called somatic mutations in airway brush samples from medium-coverage whole genome sequencing data from healthy never and ex-smokers (n=8), as well as from ex-smokers with variable degrees of COPD (n=4). Owing to the limited concordance of resulting calls between the applied tools we built a consensus, a strategy that was validated with high accuracy for cancer data.

Dataset ID	Description	Technology	Samples
EGAD00001004535	Dataset of 27 whole genome sequencing files (BAM), which cover 12 individuals out of which four suffer from COPD. From 9 individuals, there are sequencing data from blood and from lung brushings at one single site available, from another 3 there is additionally a lung brushing sequencing file from a second site available. Comparison of blood with lung brushings allows the calling of somatic mutations within a tissue.	Illumina MiSeq	27
