Germline variation and somatic alterations contribute to the molecular profile of cancers. We combine RNA with whole genome sequencing across 1,218 cancer patients determine extent germline structural variants (SVs) impact expression nearby genes. For hundreds genes, recurrent common SV breakpoints within 100 kb associate increased or decreased in tumors spanning various tissues origin. A significant fraction associations involves duplication intergenic enhancers 3′ UTR disruption. Genes altered by both SVs include ATRX CEBPA. essential cell lines BARD1 IRS2. breakpoint patterns associated patient survival GCLM. Our results capture a class phenotypic at work disease setting, including genes roles. Specific represent potential risk for genetic testing, those involving targeting implications.

Abstract Metastatic cancer is a major cause of death and associated with poor treatment efficacy. A better understanding the characteristics late-stage required to help adapt personalized treatments, reduce overtreatment improve outcomes. Here we describe largest, our knowledge, pan-cancer study metastatic solid tumour genomes, including whole-genome sequencing data for 2,520 pairs normal tissue, analysed at median depths 106× 38×, respectively, surveying more than 70 million somatic variants. The characteristic mutations lesions varied widely, that reflect those primary types, high rates duplication events (56%). Individual were relatively homogeneous, vast majority (96%) driver being clonal up 80% tumour-suppressor genes inactivated bi-allelically by different mutational mechanisms. Although genomes showed similar landscape tumours, find could contribute responsiveness therapy or resistance in individual patients. We implement an approach review clinically relevant associations their potential actionability. For 62% patients, identify genetic variants may be used stratify patients towards therapies either have been approved are clinical trials. This demonstrates importance comprehensive genomic profiling precision medicine cancer.

Abstract To increase understanding of the genomic landscape acral melanoma, a rare form melanoma occurring on palms, soles or nail beds, whole genome sequencing 87 tumors with matching transcriptome for 63 was performed. Here we report that mutational signature analysis reveals subset tumors, mostly subungual, an ultraviolet radiation signature. Significantly mutated genes are BRAF, NRAS , NF1 NOTCH2 PTEN and TYRP1 . Mutations amplification KIT also common. Structural rearrangement copy number signatures show duplication, aneuploidy complex rearrangements Complex occur recurrently associated TERT CDK4 MDM2 CCND1 PAK1 GAB2 indicating potential therapeutic options.

DNA is subject to constant chemical modification and damage, which eventually results in variable mutation rates throughout the genome. Although detailed molecular mechanisms of damage repair are well understood, impact execution across a genome remain poorly defined.To bridge gap between our understanding distributions, we developed novel method, AP-seq, capable mapping apurinic sites 8-oxo-7,8-dihydroguanine bases at approximately 250-bp resolution on genome-wide scale. We directly demonstrate that accumulation rate varies widely genome, with hot spots acquiring many times more than cold spots. Unlike single nucleotide variants (SNVs) cancers, burden correlates marks for open chromatin notably H3K9ac H3K4me2. Apurinic oxidative also highly enriched transposable elements other repetitive sequences. In contrast, observe reduction loop anchors increased load towards inactive compartments. Less found promoters, exons, termination sites, but not introns, seemingly transcription-independent GC content-dependent manner. Leveraging cancer genomic data, find locally reduced SNV coding sequence, functional elements.Our study reveals differ strongly culminate previously unappreciated mechanism safeguards regulatory regions genes from mutations.

Characterizing the mode-the way, manner or pattern-of evolution in tumours is important for clinical forecasting and optimizing cancer treatment. Sequencing studies have inferred various modes, including branching, punctuated neutral evolution, but it unclear why a particular pattern predominates any given tumour. Here we propose that tumour architecture key to explaining variety of observed genetic patterns. We examine this hypothesis using spatially explicit population genetics models demonstrate that, within biologically relevant parameter ranges, different spatial structures can generate four evolutionary modes: rapid clonal expansion, progressive diversification, branching effectively almost evolution. Quantitative indices describing classifying these modes are presented. Using indices, show our model predictions consistent with empirical observations types corresponding structures. The cell dispersal range cell-cell interactions found be essential factors accurately characterizing, controlling
