| Open AccessPrevalence and detection of low-allele-fraction variants in clinical cancer samples
High-throughput sequencing is used to identify somatic variants in cancer patients. Here, the authors perform panel-based profiling of 5095 clinical samples and demonstrate that many clinically-actionable variants have low variant allele fractions, requiring assays with high detection sensitivity.

| Open AccessUltrasensitive and high-efficiency screen of de novo low-frequency mutations by o2n-seq
Detection ofde novo, low frequency mutations is important for characterising heterogeneous cell populations, such as those found in cancer cell populations. Here the authors present o2n-seq, an ultrasensitive method with highly efficient data usage for detection of rare mutations.

| Open AccessTruncation and constitutive activation of the androgen receptor by diverse genomic rearrangements in prostate cancer
Castration-resistant prostate cancer frequently presents with persistent androgen receptor signalling. Here, the authors find that the androgen receptor is subject to genetic rearrangements, resulting in variants with ligand-independent activity.

| Open AccessLarge-scale recent expansion of European patrilineages shown by population resequencing
The origins and antiquity of the people of Europe has been much debated. Here, the authors sequence 3.7 Mb of the Y chromosome in over 300 Europeans and Middle Easterners and show a recent, continent-wide and male-specific expansion dating back to the Bronze Age.

| Open AccessDeep resequencing reveals excess rare recent variants consistent with explosive population growth
To fully catalogue rare genetic variation in humans, many samples need to be examined. In this study, Coventryet al. resequenced two genes, KCNJ11 and HHEX, in 13,715 humans, and concluded that most of the sequence variation arose recently and that variation is greater than expected.
