Study finds genetic links between alcohol dependence and psychiatric disorders

In the largest study of genetic factors linked to alcohol dependence, an international team of researchers identified a gene known to affect risk, and they determined that many other genes also contribute to risk for alcohol dependence to a lesser degree.

			Researchers discover first common genetic risk factors associated with ADHD A global team of researchers has found the first common genetic risk factors associated with attention deficit hyperactivity disorder, a complex condition affecting around 1 in 20 children.

			Genetic risk score for autism linked with outcomes of psychological treatment Depression is a common disorder for which cognitive behavioral therapy is the recommended treatment for most patients.

	Why Mosquitoes prefer some people over others: Genetic discovery A new study has tried to assess the genetic variants among mosquitoes that make them more susceptible to spreading deadly viral diseases such as dengue, yellow fever, Zika and chikungunya and more resistant to insecticides that are used to kill them.

	New Mainz-based Collaborative Research Center aims to explore DNA repair and genome stability From January 1, 2019, the German Research Foundation will be funding the new Collaborative Research Center 1361 on Regulation of DNA Repair & Genome Stability.

	A love of coffee and tea is mostly genetic The morning coffee or tea can perk one up for the day, however, for some of us these beverages are too bitter. Researchers have now found that the bitter taste experienced is all down to genes. The new study titled, “Understanding the role of bitter taste perception in coffee, tea and alcohol consumption through Mendelian randomization,” was published in the latest issue of the journal Nature Scientific Reports.

	Researchers attempt to create world's first genetically edited babies The researchers have used CRISPR to edit the genes of IVF embryos in a controversial attempt to create offspring that are resistant to disease.

	What is the Neutral Theory of Molecular Evolution? The neutral theory of molecular evolution asserts that the majority of genetic variations within a species are neutral; they are neither positive nor negative.

	Discovery would help specify role of genetics in the development of neuropsychiatric disorders Neurobiologists from I.M. Sechenov First Moscow State Medical University confirmed that stress in early age affects the mice with activated and deactivated CDH13 gene in different ways.

	Holliday Junctions in DNA Replication Holliday junctions can be formed during genetic recombination and affect many biological processes, including DNA replication and gene regulation.

	New method enhances efficiency and accuracy of single cell RNA sequencing In the era of personalized medicine, scientists are using new genetic and genomic insights to help them determine the best treatment for a given patient. In the case of cancer, the first step toward these treatments is an investigation into how tumor cells behave in an effort to figure out the best drugs to use to attack them.

	Gene-brain association occurs differently in toddlers with autism and poor language development An international team of scientists, led by researchers at the University of Cyprus and University of California San Diego School of Medicine, have identified a previously unknown, large-scale association between molecular gene expression activity in blood leukocyte cells and altered neural responses to speech in toddlers with autism as measured with functional magnetic resonance imaging (fMRI).
