Abstract

Cancer is one of the leading causes of mortality in China, and poses a threat to public health due to its increasing incidence and mortality rates. Concurrent cancer is defined as one or more organs in the same individual having ≥2 primary malignancies occurring simultaneously or successively; however, concurrent cases are rare and poorly studied. The present study recruited a Chinese family presenting multiple cases of concurrent cancer and performed whole exome sequencing in one unaffected and two affected individuals to identify the causative mutations. DNA was extracted from peripheral blood and tumor tissue samples. Following an exome capture and quality test, the qualified library was sequenced as 100 bp paired‑end reads on an Ion Torrent platform. Clean data were obtained by filtering out the low‑quality reads. Subsequently, bioinformatics analyses were performed using the clean data. After mapping and annotating in 1000 Genomes Project database, the existing SNP database and the Cancer Gene Census (CGC) database, it was revealed that the NADH:ubiquinone oxidoreductase core subunit S7 gene was a candidate gene with somatic mutations, and a subset of 16 genes were candidate genes with germline mutations. The findings of the present study may improve the understanding of the molecular pathogenesis of concurrent cancer.
