According to a latest report over 60 percent of the Americans’ ancestry can be traced through existing DNA databases. This includes even persons who have never submitted their DNA for evaluation say researchers because enough individuals have already submitted their genetic information. The latest study revealing this was published in the journal Science. Image Credit: […]Continue Reading ...
A study in Biological Psychiatry establishes an in vitro model of human neuron development to investigate genetic risk for psychiatric disease A study in Biological Psychiatry has established a new analytical method for investigating the complex genetic origins of mental illnesses using brain cells that are grown in a dish from human embryonic stem cells. […]Continue Reading ...
Some smokers have genes that predispose them to heavier smoking. Researchers looked at whether those same genes might trigger heavier drinking — and it turns out, they don’t. Several genetic variants have been identified that can contribute to how much a person smokes. These variants are essentially a genetic indicator of how heavily a person […]Continue Reading ...
The largest ever genetic analysis of over one million people has identified 535 new genes associated with high blood pressure. The international team included Professor Jo Knight of Lancaster Medical School who is Chair in Applied Data Science. The researchers concluded : “The combined effect of all associated variants shows a large aggregated risk, warranting […]Continue Reading ...
Credit: CC0 Public Domain Over 500 new gene regions that influence people’s blood pressure have been discovered in the largest global genetic study of blood pressure to date, led by Queen Mary University of London and Imperial College London. Involving more than one million participants, the results more than triple the number of blood pressure […]Continue Reading ...
The genetic differences in phyloplankton living in close geographic proximity can be great, something which long has surprised researchers. Now new research shows that the ability of phyloplankton to generate resting stages can be an important part of the explanation. Phyloplankton have ample opportunity for broad dispersal since they are small, numerous and carried by […]Continue Reading ...
The Center for Research on the Ethical, Legal and Social Implications of Psychiatric, Neurologic, and Behavioral Genetics at Columbia University Irving Medical Center (CUIMC) will bring its expertise to bear on exploring the effects of new genetic knowledge on individuals with autism spectrum disorder and their families. The Center, which was awarded a four-year renewal […]Continue Reading ...
Should researchers inform research participants, if they discover genetic disease risks in the participants? Yes, many would say, if the information is helpful to the participants. However, the value of complex genetic risk information for individuals is uncertain. In a PhD thesis from Uppsala University, Jennifer Viberg Johansson suggests that this uncertainty needs to be […]Continue Reading ...
There are 3.2 billion positions on the human genome and it requires a study of huge number of genetic variations in the populations to estimate the associations between genetic disorders and mutations. Two new studies have been published in the journal Nature. These studies have all shown the value of genetic information and understanding in […]Continue Reading ...
According to a new study there may be a genetic link to erectile dysfunction. This is the first time that such as connection has been made and this could mean that newer avenues of treatment could be explored for erectile dysfunction, explain the researchers. The results of the research have been published in the latest […]Continue Reading ...
Oct 4 2018 CHOP Scientist Proposes Interactive Info-Sharing Model, to Help Advance Precision Medicine Maybe the genetic test report your doctor ordered says your DNA contains many “variants of unknown significance.” Currently, up to 70 percent of such reports are negative or inconclusive. But suppose at a later date a researcher discovers one of those […]Continue Reading ...
An international team of scientists led by researchers from the University of Colorado School of Medicine have identified previously unknown genetic causes of mitochondrial diseases. The findings are published in the October 3 edition of the journal Nature Communications. Johan Van Hove, MD, PhD, professor of pediatrics at the CU School of Medicine, is the […]Continue Reading ...
A new study digging into the genetics of cholesterol also points to how doctors might one day use already-existing drugs to treat cardiovascular disease and diabetes. In collaboration with the Million Veteran Program, Tim Assimes, MD, PhD, associate professor of medicine, analyzed genetic data from almost 300,000 veterans, scouring the information for clues to the […]Continue Reading ...
Coronary artery disease (CAD) is the leading killer of people with type 2 diabetes, and it’s not a secret killer. Physicians can assess the risks of major coronary events for someone with diabetes for reasonably well. Among those with diabetes, there are well-established indicators of risk such as weight, fasting levels of blood glucose and […]Continue Reading ...
Many wild and cultivated plants arise through the combination of two different species. The genome of these so-called polyploid species often consists of a quadruple set of chromosomes – a double set for each parental species – and thus has about twice as many genes as the original species. About 50 years ago, evolutionary biologists […]Continue Reading ...
