An international study led by King's College London has identified a new genetic variant associated with stroke. By exploring the genetic variants linked with blood clotting – a process that can lead to a stroke – scientists have discovered a gene which is associated with large vessel and cardioembolic stroke but has no connection to small vessel stroke. http://medicalxpress.com/news/2013-02-gene-discovery-tailored-treatments.html Neuroscience Fri, 01 Feb 2013 05:08:09 EST news278917678 The study, published in PLOS Genetics on 20 December, adds to growing evidence that particular genes are involved in chronic pain and highlights this pathway as a potential target for more effective pain relief treatments for patients. http://medicalxpress.com/news/2012-12-genetic-differences-sensitivity-pain.html Genetics Thu, 20 Dec 2012 17:00:06 EST news275244800 (HealthDay)—For teens and adults who don't grow out of attention deficit hyperactivity disorder, staying on ADHD medications may help them stay out of trouble. http://medicalxpress.com/news/2012-11-adhd-drugs-criminal-behavior.html Attention deficit disorders Thu, 22 Nov 2012 04:20:01 EST news272779028 Some heart attack patients end up back in the hospital just weeks after going home. It can happen for a variety of reasons, but doctors haven't had a reliable way to predict which patients will return—until now. http://medicalxpress.com/news/2012-11-tool-doctors-heart-patients-hospitalization.html Cardiology Mon, 05 Nov 2012 12:00:01 EST news271336986 October 25, 2012 – Explosive advancement in human genome sequencing opens new possibilities for identifying the genetic roots of certain diseases and finding cures. However, so many variations among individual genomes exist that identifying mutations responsible for a specific disease has in many cases proven an insurmountable challenge. But now a new study by scientists at The Scripps Research Institute (TSRI), Scripps Health, and Scripps Translational Science Institute (STSI) reveals that by comparing the genomes of diseased patients with the genomes of people with sufficiently similar ancestries could dramatically simplify searches for harmful mutations, opening new treatment possibilities. http://medicalxpress.com/news/2012-10-genomics-ancestry-disease-riddles.html Genetics Thu, 25 Oct 2012 16:00:09 EST news270396948 Obesity is not to blame for poor educational performance, according to early findings from research funded by the Economic and Social Research Council (ESRC). In a study that combines statistical methods with genetic information, researchers dispel the false idea that being overweight has damaging educational consequences. http://medicalxpress.com/news/2012-07-obese-kids-bright-thinner-peers.html Overweight and Obesity Fri, 13 Jul 2012 04:10:21 EST news261371412 University of Minnesota School of Public Health researchers have reported two high-signal genetic markers correlated with coronary artery disease (CAD) that should help define genetic fingerprints that can signal an increased risk of developing the disease. http://medicalxpress.com/news/2012-06-genetic-proof-coronary-artery-disease.html Genetics Fri, 15 Jun 2012 09:56:47 EST news258972997 A team of global scientists, led by researchers at Intermountain Medical Center in Salt Lake City, has developed a safer and more accurate way to administer warfarin, one of the most commonly prescribed but also potentially dangerous medications in the United States. http://medicalxpress.com/news/2012-02-safer-common-potentially-dangerous-medication.html Medical research Wed, 29 Feb 2012 10:12:22 EST news249732726 Scientists have for the first time discovered sixteen new sections of the genetic code that relate to lung health -- opening up the possibility for better prevention as well as treatment for lung diseases. http://medicalxpress.com/news/2011-09-discoveries-genetics-lung-health.html Genetics Sun, 25 Sep 2011 13:26:44 EST news236175982 An international team of researchers led by neuroscientists at Mayo Clinic in Florida has found a genetic variation they say protects against Parkinson's disease. The gene variants cut the risk of developing the disease by nearly 20 percent in many populations. The study, published in the online Aug. 31 issue of Lancet Neurology, also reports the discovery of different variants of the same gene, LRRK2 -- the most important Parkinson's risk gene found to date -- that double Parkinson's risk in Caucasians and Asians. http://medicalxpress.com/news/2011-08-genetic-variation-parkinson-disease.html Parkinson's & Movement disorders Wed, 31 Aug 2011 05:36:57 EST news233987779 Researchers at the Intermountain Medical Center Heart Institute in Salt Lake City have identified the first genetic mutation ever associated with a mysterious and potentially devastating form of heart disease that affects women in the final weeks of pregnancy or the first few months after delivery. http://medicalxpress.com/news/2011-06-genetic-mutation-linked-heart-failure.html Cardiology Tue, 21 Jun 2011 14:27:29 EST news227885160 More than just a tool for predicting health, modern genetics is upending long-held assumptions about who we are.
