'Filter' hones GWAS results to help researchers avoid dead ends
A genetics research team at Johns Hopkins Medicine has solved a dilemma facing researchers who use genomewide association studies (GWAS) by developing a new approach that strategically 'filters' which genes are worth further study. The researchers hope this strategy will accelerate the study of diseases such as Parkinson's, Alzheimer's, schizophrenia and even addiction by helping researchers avoid 'dead-end paths.' They are optimistic that this strategy will gain widespread use and will save researchers time and money. (2018-03-05)

Improve evolution education by teaching genetics first
Evolution is a difficult concept for many students at all levels, however, a study publishing on May 23 in the open access journal PLOS Biology has demonstrated a simple cost-free way to significantly improve students' understanding of evolution at the secondary level: teach genetics before you teach them evolution. (2017-05-23)

Lifestyle changes can close regional obesity gap, study finds

Unprecedented study identifies 44 genetic risk factors for major depression
A global research project has mapped out the genetic basis of major depression, identifying 44 genetic variants which are risk factors for depression, 30 of which are newly discovered. The study, by the Psychiatric Genomics Consortium and co-led in the UK by King's College London, is the largest study to-date of genetic risk factors for major depression. (2018-04-26)

Genetic effects are influenced by lifestyle
The risk for developing obesity is influenced by our lifestyle as well as our genes. In a new study from Uppsala University, researchers show that our genetic risk for obesity is not static, but is influenced by our lifestyle. Results from the study have been published in the scientific journal PLOS Genetics. (2017-09-06)

A new study led by scientists from the University of Cambridge, the Institut Pasteur, Paris Diderot University, the CNRS and the genetics company 23andMe suggests that our empathy is not just a result of our education and experience but is also partly influenced by genetic variations. These results will be published in the journal Translational Psychiatry on March 12, 2018. (2018-03-11)

Several genes that regulate the disease SLE have been identified
Swedish researchers, in collaboration with foreign colleagues, have identified a number of new genes that can be tied to the disease SLE, including a gene that hopefully might be used to treat the disease in the future by regulating the production of antibodies. These unique findings are being published in three articles in the new issue of the journal Nature Genetics. (2008-01-22)

Physical inactivity and restless sleep exacerbate genetic risk of obesity
Low levels of physical activity and inefficient sleep patterns intensify the effects of genetic risk factors for obesity, according to results of a large-scale study presented at the American Society of Human Genetics (ASHG) 2017 Annual Meeting in Orlando, Fla. These results confirm and strengthen previous findings based on self-reported activity. (2017-10-20)

Sweet, bitter, fat: Genetics play a role in kids' snacking patterns, study finds
The types of snacks a child chooses could be linked to genetics, a University of Guelph study found. The study investigated whether genetic variants in taste receptors related to sweet, fat and bitter tastes influence the snacks preschoolers choose and found nearly 80 per cent carried at least one of these genotypes that could predispose them to poor snacking habits. These findings could help parents tailor their kids' diets based on their genetics of taste. (2018-02-22)

Nature versus nurture: Environment exerts greater influence on corn health than genetics
In one of the largest and most diverse leaf microbe studies to date, the team monitored the active bacteria on the leaves of 300 diverse lines of corn growing in a common environment. They were especially interested to see how corn genes affected bacteria and found there was little relationship between the two--in fact, the bacteria were much more affected by the environment, although genetics still had a small role. (2019-04-02)

Discovery of a new genetic syndrome which predisposes the body to cancer
A new syndrome caused by biallelic mutations -- those produced in both gene copies inherited from the mother and father -- in the FANCM gene predisposes the body to the appearance of tumors and causes rejection to chemotherapy treatments. Contrary to what scientists believed, the gene does not cause Fanconi anaemia. Researchers recommend modifying the clinical monitoring of patients with these mutations. (2017-09-22)

ASHG applauds passage of Canadian Genetic Non-Discrimination Act
The American Society of Human Genetics applauds yesterday's passage of S-201, the Genetic Non-Discrimination Act, in a 222-60 vote by the Parliament of Canada's House of Commons. Passage of S-201 will help ensure not only that an individual's genetic information remains private, but also that this information cannot be used in a way that harms them. It will help ensure that all Canadians can benefit from genetics-based clinical advances without fear of genetic discrimination. (2017-03-09)

Toenail fungus gives up sex to infect human hosts
The fungus that causes athlete's foot and other skin and toenail infections may have lost its ability to sexually reproduce as it adapted to grow on human hosts. The discovery that this species may be asexual -- and therefore nearly identical at the genetic level -- uncovers potential vulnerabilities that researchers could exploit in designing better antifungal medications. The findings appear online in Genetics. (2018-02-22)

Ancient Eurasian DNA sequencing is revealing links with modern humans
Until recently, very little was known about the genetic relationship between modern humans of the Upper Paleolithic age (the period of time between 50,000 and 10,000 years ago, also called the Late Stone age) and today's populations. But with direct DNA sequencing, researchers are discovering unexpected genetic connections between individuals on opposing sides of Eurasia. These suggest a complex history that may represent an early population structure that eventually led to Europeans and Asians. (2018-01-25)

Making headway in infant leukemia research
Around 600 children under the age of 15 are diagnosed with leukemia each year in Germany. The effects are especially dramatic if this severe illness develops at birth or shortly afterwards. Research carried out at the Division of Genetics at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) with support from the Institute for Human Genetics has now discovered another molecular cause for a particularly aggressive type of leukemia in infants.

Home genetic tests should be interpreted by experts
Results from at-home genetic tests are not always accurate. A new study in the journal Genetics in Medicine, published by Springer Nature, now shows that up to 40 percent of direct-to-consumer (DTC) genetic tests provide incorrect readings in the raw data. Stephany Leigh Tandy-Connor expressed concern about the fact that most DTC test results are interpreted by medical providers with limited genetic training due to a shortage of genetic counsellors and other highly trained genetic professionals available for public consultation. (2018-03-22)

Sugars in infant formulas pose risk to babies with inherited metabolic disorder
Babies with inherited intolerance of fructose face a risk of acute liver failure if they are fed certain widely available formulas containing fructose, pediatricians and geneticists are warning. Baby formula manufacturers should remove fructose or sucrose, or explicitly label their products to allow parents to avoid those sweeteners if necessary, the doctors say. (2018-05-17)

How to control traffic on cellular highways
Inside cells, protein 'motors' act like trucks on tiny cellular highways to deliver life-sustaining cargoes. Now a team led by Rutgers University-New Brunswick researchers has discovered how cells deploy enzymes to place traffic control and 'roadway under construction' signs along cellular highways. (2017-11-09)
