December 3, 2014: Researchers conduct comprehensive genomic study of sub-Saharan Africans An international team that includes researchers from the National Institutes of Health has completed the first comprehensive characterization of genomic diversity across sub-Saharan Africa. The region is the most genetically diverse in the world, yet few studies have looked into genomic risk factors for disease in Africa. The study provides clues to medical conditions in people of sub-Saharan African ancestry, and indicates that the migration from Africa in the early days of the human race was followed by a migration back into the continent.
November 19, 2014: New comprehensive view of the mouse genome finds many similarities and striking differences with human genome An international group of researchers has found powerful clues to why certain processes and systems in the mouse are so different from those in people. Building on years of mouse and gene regulation studies, they have developed a resource that can help scientists better understand how similarities and differences between mice and humans are written in their genomes. Their findings are reported by the mouse ENCODE Consortium online Nov. 19, 2014 (and in print Nov. 20) in four papers in Nature and in several other publications.
October 28, 2014: Media Availability: Researchers uncover new evidence revealing molecular paths to autism In the largest study of its kind to date, researchers have used DNA sequencing to uncover dozens of genes that heighten the risk for autism. Joseph Buxbaum, Ph.D., Icahn School of Medicine at Mount Sinai, New York City, Mark Daly, Ph.D., Broad Institute of Harvard and MIT, and their colleagues examined more than 14,000 DNA samples from affected children, parents and unrelated people. They identified changes in 107 genes that are likely to contribute to the risk for autism spectrum disorder (ASD) - a jump from the nine genes implicated in earlier studies using these approaches. The findings, reported online October 29, 2014, in Nature, provide a better understanding of some of the genetic and cellular changes in pathways and processes thought to be involved in ASD, and eventually may help lead to potential therapies.
October 23, 2014: Media Availability: TCGA study improves understanding of genetic drivers of thyroid cancer A comprehensive analysis of the genomes of nearly 500 papillary thyroid carcinomas (PTC) - the most common form of thyroid cancer - has provided new insights into the roles of frequently mutated cancer genes and other genomic alterations that drive disease development. The findings also may help improve diagnosis and treatment. Investigators with The Cancer Genome Atlas (TCGA) Research Network identified new molecular subtypes that will help clinicians determine which tumors are more aggressive and which are more likely to respond to certain treatments.

August 1, 2014: NIH awards $14.5 million to research groups studying newest DNA sequencing techniques A number of micro-sized technologies - such as nanopores and microfluidics - are among the approaches researchers will use to develop high quality, low cost DNA sequencing technology through new grants from the National Institutes of Health. The grants, which total approximately $14.5 million to eight research teams over two to four years as funds become available, are the last to be awarded by the Advanced DNA Sequencing Technology program of the National Human Genome Research Institute (NHGRI), a part of NIH.
August 1, 2014: Genotype-Tissue Expression project expands functional studies of genomic variation The National Institutes of Health has awarded eight grants as part of the Genotype-Tissue Expression (GTEx) project to explore how human genes are expressed and regulated in different tissues, and the role that genomic variation plays in modulating that expression. The GTEx awards will contribute to a resource database and tissue bank that researchers can use to study how inherited genomic variants - inherited spelling changes in the DNA code - may influence gene activity and lead to disease. The grants will add data from analyses of tissue samples whose collection began in 2010, as well as expand the resource database and tissue bank.
July 23, 2014: TCGA researchers identify four subtypes of stomach cancer Stomach cancers fall into four distinct molecular subtypes researchers with The Cancer Genome Atlas (TCGA) Network have found. In the study, published online July 23, 2014, in Nature, the scientists report that this discovery could change how researchers think about developing treatments for stomach cancer, also called gastric cancers or gastric adenocarcinomas.
July 9, 2014: Study identifies novel genomic changes in the most common type of lung cancer Researchers from The Cancer Genome Atlas (TCGA) Research Network have identified novel mutations in a well-known cancer-causing pathway in lung adenocarcinoma, the most common subtype of lung cancer. Knowledge of these genomic changes may expand the number of possible therapeutic targets for this disease and potentially identify a greater number of patients with treatable mutations because many potent cancer drugs that target these mutations already exist.
