    Papillary renal cell carcinoma (pRCC) is a subtype of kidney cancer characterized by highly variable clinical behaviour. Here the authors sequence either the genomes or exomes of 31 pRCCs and identify several genes in sub-clones and large copy number variants in major clones that may be important drivers of pRCC.

    One of the biggest bottlenecks in large-scale DNA synthesis is the retrieval of target clonal DNA from high-density sequencing platforms. Here, the authors present a method called ‘Sniper Cloning’ that allows for precise mapping of target clone features and rapid retrieval of targets for full utilization of DNA clones.

    Next-generation sequencing technologies vary in performance, which is often measured by metrics such as sequencing speed, accuracy and read length. Here, the authors present a new sequencing by synthesis method that monitors polymerase binding to DNA, and suggest that this method has the potential to generate longer and faster reads.

    Strand-specific RNA-seq (ssRNA-seq) data often lack information on 5′ and 3′ ends of transcripts. Here the authors present a novel method for ssRNA-seq that enables the simultaneous profiling of gene expression, TSSs and polyadenylation sites at near-base resolution with a single library.

    Type 2 diabetes (T2D) is a highly heterogeneous disease with a strong genetic component. Here the authors examine genome-wide methylation patterns in T2D-discordant, T2D-concordant and healthy concordant monozygotic twin pairs, and identify DNA methylation signals that may represent new biomarkers or drug targets for T2D.

    The microbial RNA-guided CRISPR/Cas9 system has robust genome-editing activities, but the off-target effects of the Cas9 nuclease have only recently begun to be analysed. Here the authors provide evidence for high specificity of the Cas9 nuclease on targeting of the Tafazzin gene in human-induced pluripotent stem cells and demonstrate the impact of single-nucleotide variations of the human genome on Cas9 specificity.

    Plasmodium falciparum, known to cause malaria in humans, evolved from parasites of African Great Apes. Here, the authors compare the genome of the human parasite, P. falciparum, with those of two related chimpanzee parasites, P. reichenowi and P. gaboni, and provide insight into the genetic basis of P. falciparumadaptation to human hosts.

    Common methods to detect adenosine-to-inosine RNA editing sites rely on mapping short RNA reads to the genome while allowing only a limited number of mismatches. Here, Porath et al. present a novel RNA-seq based approach to identify hyper-edited reads that significantly expands the RNA editome.

    Although psoriasis is a chronic disorder affecting approximately 2% of the population, little is known about the underlying genetic architecture. Here, the authors carry out exome sequencing in a large Han Chinese cohort of psoriasis patients and healthy controls, and identify three new genes that may increase risk of developing the disease.
