Recurrent genetic deletion linked to autism

Loss of a small portion of chromosome 16, known as 16p11.2, is significantly associated with autism researchers report in the journal Human Molecular Genetics. Although this genetic microdeletion occurred in only 4 out of 712 subjects with autism (0.6 percent), it is the second most common recurrent genomic disorder associated with autism, which affects about 1 out of 160 children in the United States.

   01-10-2008 · EurekAlert!
   UCLA scientists used language onset -- the age when a child speaks his first word -- as a tool for identifying a new gene linked to autism. The team also discovered that the gene is most active in developing brain regions involved with language and thought. Interestingly, evidence for the genetic link came from the DNA of families with autistic boys, not those with autistic girls.

   Twenty-one years after they first described a fatal genetic disorder in Missouri and Arkansas families, scientists at Washington University School of Medicine in St. Louis have linked the condition to mutations in a gene known as TREX1. The identification will accelerate efforts to understand both the disorder and a broader range of more common conditions that affect small blood vessels, including diabetes.

   Biologists at Harvard University and the University of California, San Diego, have found that a simple interaction between just two genes determines the patterns of fur coloration that camouflage mice against their background, protecting them from many predators. The work marks one of the few instances in which specific genetic changes have been linked to an organism's ability to survive in the wild.

    The Rett Syndrome Research Foundation announces results of a landmark study reversing the symptoms of Rett Syndrome in a genetic mouse model. The findings, by Adrian Bird, Ph.D., of the University of Edinburgh and Chairman of the RSRF Scientific Advisory Board, appear online in Science Express on February 8, 2007. Rett Syndrome is a severe childhood neurological disease that is the most physically disabling of the autism spectrum disorders. The experiments were funded in part by the Rett Syndrome Research Foundation.
