...causes of autism remain largely shrouded in mystery, but there are some types of the disorder that can be traced to specific gene defects. The most common of these - responsible for roughly 5% of autism cases - is a flaw in the X chromosome that causes a condition known as Fragile X Syndrome. Because the defect has been studied on a molecular level, it provides a unique window into understanding autism - and treating it. And that is why a paper published in this week's issue of the journal Neuron is bound to generate excitement, even though the work was done...
...Four decades later Wald’s legacy is very much alive at Harvard—the discovery that earned him a champagne bash would lead to advances in gene therapy and an in-depth understanding of biological messaging systems...
...Medical School genetics professor George M. Church, the Personal Genome Project aims to find a process that makes gene sequencing as affordable...
Everyone can learn from their mistakes - but some people have genes that may make it harder. That's the message from German researchers, writing in tomorrow's issue of the journal Science, who have shown how a common gene variant affects some people's ability to respond to, and learn from, the negative repercussions of their actions...
...face, depending on the symbol he had chosen. All men were equally good at learning to pick the symbols that won them a smiley face, but some men were worse than others at avoiding the ones that resulted in sad faces. Those men, it turns out, had a particular gene variant, or allele, that reduces the density of receptors for dopamine - a neurotransmitter that plays a key role in motivation, pleasure and addiction - in certain areas of the brain. Brain scans also showed significantly less activity in those areas in response to the sad-faced negative feedback...
