WebWe compared the relative copy number values for 15 genes frequently altered in HGSOC (table S4). Analysis of plasma cfDNA after size selection revealed a large number of SCNAs that were not observed in the same samples without size selection , including amplifications in key genes such as NF1, TERT, and MYC (fig. S13). WebAbstract: Determining how somatic copy number alterations (SCNAs) promote cancer is an important goal. We characterized SCNA patterns in 4,934 cancers from The Cancer Genome Atlas Pan-Cancer data set. Whole-genome doubling, observed in 37% of cancers, was associated with higher rates of every other type of SCNA, TP53 mutations, CCNE1 …
