The finding, published in the October 8 issue of the journal Nature, implicates a neuronal gene not previously tied to the disorder and more broadly, underscores a role for common DNA variation. In addition, the new research highlights two other regions of the genome, which are likely to contain rare genetic differences that may also influence autism risk. http://www.physorg.com/news174140329.html Medicine & Health - Genetics Wed, 07 Oct 2009 13:19:11 EST news174140329 Scientists look for clues about therapies and cures for life-threatening childhood illnesses in children's DNA -- it seems only logical to do so. But the decision as to who should have access to DNA samples from children provides a unique ethical conundrum, says a Tel Aviv University researcher in a recent publication for the esteemed journal Science, co-authored by colleagues from The Netherlands and Canada. The recommendations, which call for new policies on access to biobanked children's DNA, could shape America's legislation on the issue in the coming years. http://www.physorg.com/news174052464.html Medicine & Health - Genetics Tue, 06 Oct 2009 13:40:07 EST news174052464 (PhysOrg.com) -- Scientists are close to discovering how normal breast cells become cancerous, according to research by Cambridge scientists published today. http://www.physorg.com/news174053855.html Medicine & Health - Genetics Tue, 06 Oct 2009 13:18:49 EST news174053855 Duke University Medical Center and National Cancer Institute scientists have discovered that a novel genetic alteration - a second copy of an entire gene - is a cause of familial chordoma, an uncommon form of cancer arising in bones and frequently affecting the nervous system. http://www.physorg.com/news173881901.html Medicine & Health - Genetics Sun, 04 Oct 2009 14:20:03 EST news173881901 Vincent van Gogh cut off his ear.
