Description: Recent advances in genome sequencing technologies provide unprecedented opportunities to characterize individual genomic landscapes and identify mutations relevant for diagnosis and therapy. Specifically, whole-exome sequencing using next-generation sequencing (NGS) technologies is gaining popularity in the human genetics community due to the moderate costs, manageable data amounts and straightforward interpretation of analysis results. While whole-exome and, in the near future, whole-genome sequencing are becoming commodities, data analysis still poses significant challenges and led to the development of a plethora of tools supporting specific parts of the analysis workflow or providing a complete solution. Here, we surveyed 205 tools for whole-genome/whole-exome sequencing data analysis supporting five distinct analytical steps: quality assessment, alignment, variant identification, variant annotation and visualization. We report an overview of the functionality, features and specific requirements of the individual tools. We then selected 32 programs for variant identification, variant annotation and visualization, which were subjected to hands-on evaluation using four data sets: one set of exome data from two patients with a rare disease for testing identification of germline mutations, two cancer data sets for testing variant callers for somatic mutations, copy number variations and structural variations, and one semi-synthetic data set for testing identification of copy number variations. Our comprehensive survey and evaluation of NGS tools provides a valuable guideline for human geneticists working on Mendelian disorders, complex diseases and cancers.

Description: The reconstruction of the history of rearrangements and the reconstruction of ancestral genomes are some of the challenges of bioinformatics today. Many algorithms already exist, treating one or the other question but none treating both. These reconstructions are interdependent and we argue on the interest of treating both problems in parallel to lead to a richer and more complete output. We also argue on the importance of redefining several steps of these algorithms to improve both reconstructions: the identification of synteny blocks has to be as precise as possible, and the treatment of multiple genomes has to be based on pairwise comparisons to ensure the most detailed reconstructions. In this article, we highlight novel solutions to these points and focus on the need of explicitly treating overlapping, included, duplicated and unsigned synteny blocks. To do so, we introduce the new notion of synteny pack , which is a representation of local hypothetical intermediate ancestral genomes. We discuss a number of examples on yeast genomes to illustrate the importance of such a definition.

Description: We introduce a spectroscopic method that determines nonlinear quantum mechanical response functions beyond the optical diffraction limit and allows direct imaging of nanoscale coherence. In established coherent two-dimensional (2D) spectroscopy, four-wave-mixing responses are measured using three ingoing waves and one outgoing wave; thus, the method is diffraction-limited in spatial resolution. In coherent 2D nanoscopy, we use four ingoing waves and detect the final state via photoemission electron microscopy, which has 50-nanometer spatial resolution. We recorded local nanospectra from a corrugated silver surface and observed subwavelength 2D line shape variations. Plasmonic phase coherence of localized excitations persisted for about 100 femtoseconds and exhibited coherent beats. The observations are best explained by a model in which coupled oscillators lead to Fano-like resonances in the hybridized dark- and bright-mode response.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aeschlimann, Martin -- Brixner, Tobias -- Fischer, Alexander -- Kramer, Christian -- Melchior, Pascal -- Pfeiffer, Walter -- Schneider, Christian -- Struber, Christian -- Tuchscherer, Philip -- Voronine, Dmitri V -- New York, N.Y. -- Science. 2011 Sep 23;333(6050):1723-6. doi: 10.1126/science.1209206.

Description: Arthritis is a leading cause of disability, and when nonoperative methods have failed, a prosthetic implant is a cost-effective and clinically successful treatment. Metal-on-metal replacements are an attractive implant technology, a lower-wear alternative to metal-on-polyethylene devices. Relatively little is known about how sliding occurs in these implants, except that proteins play a critical role and that there is a tribological layer on the metal surface. We report evidence for graphitic material in the tribological layer in metal-on-metal hip replacements retrieved from patients. As graphite is a solid lubricant, its presence helps to explain why these components exhibit low wear and suggests methods of improving their performance; simultaneously, this raises the issue of the physiological effects of graphitic wear debris.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liao, Y -- Pourzal, R -- Wimmer, M A -- Jacobs, J J -- Fischer, A -- Marks, L D -- 1RC2AR058993-01/AR/NIAMS NIH HHS/ -- New York, N.Y. -- Science. 2011 Dec 23;334(6063):1687-90. doi: 10.1126/science.1213902.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Materials Science and Engineering, Northwestern University, Evanston, IL 60201, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22194573" target="_blank"〉PubMed〈/a〉

Description: Genetic mutations cause primary immunodeficiencies (PIDs) that predispose to infections. Here, we describe activated PI3K-delta syndrome (APDS), a PID associated with a dominant gain-of-function mutation in which lysine replaced glutamic acid at residue 1021 (E1021K) in the p110delta protein, the catalytic subunit of phosphoinositide 3-kinase delta (PI3Kdelta), encoded by the PIK3CD gene. We found E1021K in 17 patients from seven unrelated families, but not among 3346 healthy subjects. APDS was characterized by recurrent respiratory infections, progressive airway damage, lymphopenia, increased circulating transitional B cells, increased immunoglobulin M, and reduced immunoglobulin G2 levels in serum and impaired vaccine responses. The E1021K mutation enhanced membrane association and kinase activity of p110delta. Patient-derived lymphocytes had increased levels of phosphatidylinositol 3,4,5-trisphosphate and phosphorylated AKT protein and were prone to activation-induced cell death. Selective p110delta inhibitors IC87114 and GS-1101 reduced the activity of the mutant enzyme in vitro, which suggested a therapeutic approach for patients with APDS.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3930011/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3930011/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Angulo, Ivan -- Vadas, Oscar -- Garcon, Fabien -- Banham-Hall, Edward -- Plagnol, Vincent -- Leahy, Timothy R -- Baxendale, Helen -- Coulter, Tanya -- Curtis, James -- Wu, Changxin -- Blake-Palmer, Katherine -- Perisic, Olga -- Smyth, Deborah -- Maes, Mailis -- Fiddler, Christine -- Juss, Jatinder -- Cilliers, Deirdre -- Markelj, Gasper -- Chandra, Anita -- Farmer, George -- Kielkowska, Anna -- Clark, Jonathan -- Kracker, Sven -- Debre, Marianne -- Picard, Capucine -- Pellier, Isabelle -- Jabado, Nada -- Morris, James A -- Barcenas-Morales, Gabriela -- Fischer, Alain -- Stephens, Len -- Hawkins, Phillip -- Barrett, Jeffrey C -- Abinun, Mario -- Clatworthy, Menna -- Durandy, Anne -- Doffinger, Rainer -- Chilvers, Edwin R -- Cant, Andrew J -- Kumararatne, Dinakantha -- Okkenhaug, Klaus -- Williams, Roger L -- Condliffe, Alison -- Nejentsev, Sergey -- 095198/Wellcome Trust/United Kingdom -- 095198/Z/10/Z/Wellcome Trust/United Kingdom -- 095691/Wellcome Trust/United Kingdom -- BB/J004456/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- MC_U105184308/Medical Research Council/United Kingdom -- U105184308/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2013 Nov 15;342(6160):866-71. doi: 10.1126/science.1243292.
