December 8, 2014: Genetic errors linked to aging underlie leukemia that develops after cancer treatment From Washington University in St. Louis: For a small percentage of cancer patients, treatment aimed at curing the disease leads to a form of leukemia with a poor prognosis. Conventional thinking goes that chemotherapy and radiation therapy induce a barrage of damaging genetic mutations that kill cancer cells yet inadvertently spur the development of acute myeloid leukemia (AML), a blood cancer. But a new study at Washington University School of Medicine in St. Louis challenges the view that cancer treatment in itself is a direct cause of what is known as therapy-related AML. The team's findings, reported Dec. 8 in the journal Nature, open new avenues for research to predict which patients are at risk of developing therapy-related AML and to find ways to prevent it. The research was funded in part by the National Human Genome Research Institute.
November 24, 2014: ASU, IBM collaboration moves ultrafast, low-cost DNA sequencing technology one step closer to reality From Arizona State University: A team of scientists from Arizona State University's Biodesign Institute and IBM's T.J.

Principal investigators from the H3Africa Initiative - a part of the NIH Common Fund - contributed to the findings.
August 27, 2014: Humans, flies, worms: Researchers work to understand gene expression across organisms From Stanford University: Researchers at the Stanford University School of Medicine have found that although many aspects of regulatory networks are conserved among the three distantly related organisms, other differences have emerged over evolutionary time. These differences may explain why, for example, worms slither, flies fly and humans walk on two legs, even though they all use the same basic genetic building blocks. Under the Model Organism ENCyclopedia of DNA Elements (modENCODE) Project - the research was conducted as part of a multi-institutional collaborative effort to understand more about how organisms control the expression of their genes to generate neurons, muscles, skin, blood and all of the other types of cells and tissues necessary for complex life - all at the exactly right time and place in the body. NHGRI funded the research.

July 14, 2014: Study Finds Cause of Mysterious Food Allergy, Suggests New Treatment Strategy From Cincinnati Children's: New research in Nature Genetics identifies a novel genetic and molecular pathway in the esophagus that causes eosinophilic esophagitis (EoE), opening up potential new therapeutic strategies for an enigmatic and hard-to-treat food allergy. EoE is a chronic inflammatory disorder of the esophagus. The condition is triggered by allergic hypersensitivity to certain foods and an over-accumulation in the esophagus of white blood cells called eosinophils (part of the body's immune system). EoE can cause a variety of gastrointestinal complaints including reflux-like symptoms, vomiting, difficulty swallowing, tissue scarring, fibrosis, the formation of strictures and other medical complications. NHGRI helped fund the research.
July 14, 2014: Media Availability: Scientists Deepen Genetic Understanding of Eosinophilic Esophagitis From the National Institute of Allergy and Infectious Diseases:Scientists funded by the National Institutes of Health (NIH) have identified genetic markers associated with eosinophilic esophagitis (EoE), an inflammatory disease characterized by high levels of immune cells called eosinophils in the esophagus. Their findings suggest that several genes are involved in the development of EoE, which can cause difficulty eating and often is associated with food allergies. The findings also may help explain why the disease specifically affects the esophagus. The work was supported in part by the Consortium of Food Allergy Research, which is funded by NIH's National Institute of Allergy and Infectious Diseases and National Institute of Diabetes and Digestive and Kidney Diseases, ad the National Human Genome Research Institute.

April 24, 2014: Genetic legacy from the Ottoman Empire: Single mutation causes rare brain disorder From Yale: An international team of researchers have identified a previously unknown neurodegenerative disorder and discovered it is caused by a single mutation in one individual born during the height of the Ottoman Empire in Turkey about 16 generations ago.The genetic cause of the rare disorder was discovered during a massive analysis of the individual genomes of thousands of Turkish children suffering from neurological disorders. Two papers published in the April 24 issue of the journal Cell document the devastating effects of a mutation in the CLP1 gene. Funding for the study was provided in part by the National Human Genome Research Institute.
April 24, 2014: Researchers Discover New Genetic Brain Disorder in Humans From UCSD: A newly identified genetic disorder associated with degeneration of the central and peripheral nervous systems in humans, along with the genetic cause, is reported in the April 24, 2014 issue of Cell. By performing DNA sequencing of more than 4,000 families affected by neurological problems, the two research teams independently discovered that a disease marked by reduced brain size and sensory and motor defects is caused by a mutation in a gene called CLP1, which is known to regulate tRNA metabolism in cells. Insights into this rare disorder, the researchers said, may have important implications for the future treatment of more common neurological conditions. Funding for the study was provided in part by the National Human Genome Research Institute.
April 11, 2014: Yeast provides genetic clues on drug response From the University of British Columbia: Researchers at the University of British Columbia exposed 6,000 strains of yeast to 3,000 drugs. Yeast strains were modified so their response could be measured. Researchers found that the yeast cells have about 50 main ways in which they react to any drug.These 50 major response types, known as gene signatures, are like fingerprints that identify all genes and their relevance to a specific drug treatment. This relatively small number of gene signatures means that it might be possible to eventually use a person's genome to predict their drug response. It could also make it easier to identify more effective therapies. The study was published in the April 10 issue of Science. The study was supported in part by a grant from the National Human Genome Research Institute.
April 7, 2014: Amino acid fingerprints revealed in new study From Arizona State University: Stuart Lindsay and his colleagues at Arizona State University's Biodesign Institute have taken a major step in demonstrating the accurate identification of amino acids, by briefly pinning each in a narrow junction between a pair of flanking electrodes and measuring a characteristic chain of current spikes passing through successive amino acid molecules. The new work advances the prospect of clinical protein sequencing and the discovery of new biomarkers-early warning beacons signaling disease. Further, protein sequencing may radically transform patient treatment, enabling precise monitoring of disease response to therapeutics, at the molecular level. The group's research results are reported in the advanced online edition of the journal Nature Nanotech. The current research received funding from the National Institute of Health's National Human Genome Research Institute (NHGRI).

The researchers, led by scientists at the NIH's National Institute of Allergy and Infectious Diseases (NIAID), observed that the syndrome's diverse symptoms are the result of mutations in a single gene associated with sugar metabolism. They plan to evaluate certain types of sugars as a potential treatment for people with this rare genetic condition in an upcoming clinical trial. The study, published in the Journal of Allergy and Clinical Immunology, was conducted by scientists from NIAID, the National Human Genome Research Institute and the National Institute of Neurological Disorders and Stroke, all components of NIH, and collaborators.
March 3, 2014: Media Availability:Study of Antibody Evolution Charts Course toward HIV Vaccine From the National Institute of Allergy and Infectious Diseases: In an advance for HIV vaccine research, a scientific team has discovered how the immune system makes a powerful antibody that blocks HIV infection of cells by targeting a site on the virus called V1V2. Many researchers believe that if a vaccine could elicit potent antibodies to a specific conserved site in the V1V2 region, one of a handful of sites that remains constant on the fast-mutating virus, then the vaccine could protect people from HIV infection. Analyses of the results of a clinical trial of the only experimental HIV vaccine to date to have modest success in people suggest that antibodies to sites within V1V2 were protective. The new findings point the way toward a potentially more effective vaccine that would generate V1V2-directed HIV neutralizing antibodies. The research, published in the journal Nature, is from a collaboration of authors, including Jim Mullikin, director of the NIH Intramural Sequencing Center, administered by NHGRI.
March 3, 2014: Study pinpoints protective mutations for type 2 diabetes From the Broad Institute: An international team led by researchers at the Broad Institute and Massachusetts General Hospital (MGH) has identified mutations in a gene that can reduce the risk of developing type 2 diabetes, even in people who have risk factors such as obesity and old age. The results focus the search for developing novel therapeutic strategies for type 2 diabetes; if a drug can be developed that mimics the protective effect of these mutations, it could open up new ways of preventing this devastating disease. NHGRI helped fund the research.

February 28, 2014: New method IDs working copies of genes in human cells; could help diagnose sick tissues early From Harvard Medical School: In biology, as in real estate, location matters. Working copies of active genes - called messenger RNAs or mRNAs - are positioned strategically throughout living tissues, and their location often helps regulate how cells and tissues grow and develop. Now a team at the Wyss Institute of Biologically Inspired Engineering at Harvard University and Harvard Medical School, in collaboration with the Allen Institute for Brain Science, has developed a new method that allows scientists to pinpoint thousands of mRNAs and other types of RNAs at once in intact cells - all while determining the sequence of letters, or bases, that identify them and reveal what they do. The project was funded by NHGRI's Centers of Excellence in Genomic Science.
February 10, 2014: Shortening guide RNA markedly improves specificity of CRISPR-Cas nucleases From Massachusetts General Hospital: A simple adjustment to a powerful gene-editing tool may be able to improve its specificity. In a report receiving advance online publication in Nature Biotechnology, Massachusetts General Hospital (MGH) investigators describe how adjusting the length of the the guide RNA (gRNA) component of the synthetic enzymes called CRISPR-Cas RNA-guided nucleases (RGNs) can substantially reduce the occurrence of DNA mutations at sites other than the intended target, a limitation the team had previously described just last year. NHGRI helped fund the study.
January 24, 2014: Study expands the cancer genomics universe From The Broad Institute: A landmark study across many cancer types reveals that the universe of cancer mutations is much bigger than previously thought. By analyzing the genomes of thousands of patients' tumors, a Broad Institute-led research team has discovered many new cancer genes - expanding the list of known genes tied to these cancers by 25 percent. Moreover, the study shows that many key cancer genes still remain to be discovered. The team's work, which lays a critical foundation for future cancer drug development, also shows that creating a comprehensive catalog of cancer genes for scores of cancer types is feasible with as few as 100,000 patient samples. Funding for these studies was provided in part by the National Human Genome Research Institute.
January 22, 2014: New studies show that many rare mutations contribute to schizophrenia risk From The Broad Institute: Researchers from the Broad Institute and several partnering institutions have taken a closer look at the human genome to learn more about the genetic underpinnings of schizophrenia.

NHGRI helped establish the Undiagnosed Diseases Program.
January 22, 2014: Study shows 1 in 5 women with ovarian cancer has inherited predisposition From Washington University in St. Louis: A new study conservatively estimates that one in five women with ovarian cancer has inherited genetic mutations that increase the risk of the disease, according to research at Washington University School of Medicine in St. Louis. Most women in the study would have been unaware of a genetic predisposition to ovarian cancer because they didn't have strong family histories that suggested it.The research, published Jan. 22 in Nature Communications, is the first large-scale analysis of the combined contributions of inherited and acquired mutations in a major cancer type.NHGRI helped fund the study.
January 19, 2014:Decoded: DNA of blood-sucking worm that infects world's poor From Washington University in St. Louis: Going barefoot in parts of Africa, Asia and South America contributes to hookworm infections, which afflict an estimated 700 million of the world's poor. The parasitic worm lives in the soil and enters the body through the feet. By feeding on victims' blood, the worms cause anemia and, in children, stunted growth and learning problems. Now, researchers at Washington University School of Medicine in St. Louis have decoded the genome of the hookworm, Necator americanus, finding clues to how it infects and survives in humans and to aid in development of new therapies to combat hookworm disease. The research is published Jan. 19 in Nature Genetics. The genome sequencing and annotation work was funded by NHGRI.
January 9, 2014: Elephant shark genome decoded From Washington University in St. Louis: An international team of researchers has sequenced the genome of the elephant shark, a curious-looking fish with a snout that resembles the end of an elephant's trunk. The elephant shark and its cousins the sharks, rays, skates and chimaeras are the world's oldest-living jawed vertebrates. But their skeletons are made of cartilage rather than bone, making this group of vertebrates an oddity on the evolutionary tree.
