Translating genes into health   pp4 - 5
Larry J Kricka and Chiara Di Resta
doi:10.1038/ng.2510
A major challenge for genomics is to provide clinical benefits to the genetically diverse human population. Genome science has achieved a catalog of mutations and informative SNPs. Next-generation sequencing is rapidly delivering thousands of complete human genomes, but understanding and applying genomic knowledge remains a daunting undertaking. These challenges and opportunities for genomic medicine were central themes of the Golden Helix Symposium held in Turin, Italy, 18-21 April 2012.

Clostridium difficile healthcare-associated epidemics   pp6 - 7
David A Rasko
doi:10.1038/ng.2499
A new study reports whole-genome sequencing of a large collection of healthcare-associated C. difficile isolates, followed by comparative genomics and phylogenetic analyses. This work provides insight into the emergence of the current C. difficile epidemic 027/BI/NAP1 clone, which can be separated into two lineages on the basis of both SNPs and larger genetic changes mediated by mobile elements.

A tumor-specific stem cell   pp7 - 9
Ciara Metcalfe and Frederic J de Sauvage
doi:10.1038/ng.2502
Cancer stem cells are thought to share many characteristics with their normal stem cell counterparts, raising concerns about the ability to selectively target them. A new study shows that Dclk1 marks cancer, but not normal, stem cells in the intestine and that targeting this population results in adenoma collapse without affecting normal tissue.

Genomics and fruit crop selection   pp9 - 10
Patrick Wincker
doi:10.1038/ng.2498
Two new studies explore the origin of domesticated fruit species through whole-genome sequencing of modern representatives and comparative analysis of closely related subspecies. Analysis of the watermelon and sweet orange genomes detects the absence of recent duplication events and leads to insights into traits related to their domestication.

H3K9 methylation is a barrier during somatic cell reprogramming into iPSCs   pp34 - 42
Jiekai Chen, He Liu, Jing Liu, Jing Qi, Bei Wei, Jiaqi Yang, Hanquan Liang, You Chen, Jing Chen, Yaran Wu, Lin Guo, Jieying Zhu, Xiangjie Zhao, Tianran Peng, Yixin Zhang, Shen Chen, Xuejia Li, Dongwei Li, Tao Wang and Duanqing Pei
doi:10.1038/ng.2491
Duanqing Pei and colleagues show that BMP signaling to histone H3 lysine 9 methylation is a barrier to reprogramming somatic cells into induced pluripotent cells (iPSCs) and that its removal promotes the formation of fully reprogrammed iPSCs from pre-iPSCs. pre-iPSCs exhibit pluripotent properties but do not activate the core pluripotent network.

Genome-wide association study dissects the genetic architecture of oil biosynthesis in maize kernels   pp43 - 50

doi:10.1038/ng.2484
Maize oil is an important food and energy source. Now, Jianbing Yan and colleagues report a genome-wide association study in maize for maize kernel oil composition. They analyzed 368 maize lines with 1.06 million SNPs genome-wide and found 74 loci associated with maize kernel oil concentration and fatty acid composition.

Recessive mutations in EPG5 cause Vici syndrome, a multisystem disorder with defective autophagy   pp83 - 87
Thomas Cullup, Ay Lin Kho, Carlo Dionisi-Vici, Birgit Brandmeier, Frances Smith, Zoe Urry, Michael A Simpson, Shu Yau, Enrico Bertini, Verity McClelland, Mohammed Al-Owain, Stefan Koelker, Christian Koerner, Georg F Hoffmann, Frits A Wijburg, Amber E ten Hoedt, R Curtis Rogers, David Manchester, Rie Miyata, Masaharu Hayashi, Elizabeth Said, Doriette Soler, Peter M Kroisel, Christian Windpassinger, Francis M Filloux, Salwa Al-Kaabi, Jozef Hertecant, Miguel Del Campo, Stefan Buk, Istvan Bodi, Hans-Hilmar Goebel, Caroline A Sewry, Stephen Abbs, Shehla Mohammed, Dragana Josifova, Mathias Gautel and Heinz Jungbluth
doi:10.1038/ng.2497
Heinz Jungbluth and colleagues report the identification of mutations in EPG5 that cause Vici syndrome, characterized by callosal agenesis, cataracts, cardiomyopathy, combined immunodeficiency and hypopigmentation. EPG5 encodes a regulator of autophagy, and the identified mutations cause defective autophagosomal function.

Mutations in GNAL cause primary torsion dystonia   pp88 - 92
Tania Fuchs, Rachel Saunders-Pullman, Ikuo Masuho, Marta San Luciano, Deborah Raymond, Stewart Factor, Anthony E Lang, Tsao-Wei Liang, Richard M Trosch, Sierra White, Edmond Ainehsazan, Denis Hervé, Nutan Sharma, Michelle E Ehrlich, Kirill A Martemyanov, Susan B Bressman & Laurie J Ozelius
doi:10.1038/ng.2496
Laurie Ozelius and colleagues identify mutations in GNAL in families with primary torsion dystonia, a movement disorder characterized by repetitive twisting muscle contractions and postures. GNAL encodes G[alpha]olf, a stimulatory G protein [alpha] subunit.

Mutations in AP2S1 cause familial hypocalciuric hypercalcemia type 3   pp93 - 97
M Andrew Nesbit, Fadil M Hannan, Sarah A Howles, Anita A C Reed, Treena Cranston, Clare E Thakker, Lorna Gregory, Andrew J Rimmer, Nigel Rust, Una Graham, Patrick J Morrison, Steven J Hunter, Michael P Whyte, Gil McVean, David Buck and Rajesh V Thakker
doi:10.1038/ng.2492
Rajesh Thakker and colleagues show that missense mutations affecting codon 15 of AP2S1 cause familial hypocalciuric hypercalcemia type 3, a disorder of calcium homeostasis. AP2S1 encodes a protein involved in clathrin-mediated endocytosis, and the mutations probably cause disease by disrupting internalization of the calcium-sensing receptor CaSR.

Dclk1 distinguishes between tumor and normal stem cells in the intestine   pp98 - 103
Yuki Nakanishi, Hiroshi Seno, Ayumi Fukuoka, Taro Ueo, Yuichi Yamaga, Takahisa Maruno, Naoko Nakanishi, Keitaro Kanda, Hideyuki Komekado, Mayumi Kawada, Akihiro Isomura, Kenji Kawada, Yoshiharu Sakai, Motoko Yanagita, Ryoichiro Kageyama, Yoshiya Kawaguchi, Makoto M Taketo, Shin Yonehara and Tsutomu Chiba
doi:10.1038/ng.2481
Hiroshi Seno and colleagues report that Dclk1 selectively marks intestinal tumor stem cells. They further show that specific ablation of these cells in a mouse tumor model results in a pronounced regression of polyps without apparent damage to normal intestinal tissue.

MCT1-mediated transport of a toxic molecule is an effective strategy for targeting glycolytic tumors   pp104 - 108
Kivanç Birsoy, Tim Wang, Richard Possemato, Omer H Yilmaz, Catherine E Koch, Walter W Chen, Amanda W Hutchins, Yetis Gultekin, Tim R Peterson, Jan E Carette, Thijn R Brummelkamp, Clary B Clish & David M Sabatini
doi:10.1038/ng.2471
David Sabatini and colleagues report an insertional mutagenesis screen in haploid cells for resistance to the cancer drug candidate 3-bromopyruvate (3-BrPA). They find that SLC16A1, the gene that encodes MCT1, is frequently inactivated. MCT1 expression is required and sufficient for 3-BrPA uptake by cancer cells and may be used to predict cancers that are sensitive to 3-BrPA.

Trevor Lawley and colleagues report whole-genome sequencing of a large global collection of Clostridium difficile, the most common cause of healthcare-associated infection in the developed world. Their phylogenetic analysis traces the spread of this pathogen through healthcare-associated epidemics worldwide.
