(Medical Xpress)—Research out of the George Washington University (GW), published in the journal Proceedings of the National Academy of Sciences (PNAS), reveals another piece of the puzzle in a genetic developmental disorder that causes behavioral diseases such as autism. Anthony-Samuel LaMantia, Ph.D., professor of pharmacology and physiology at the GW School of Medicine and Health Sciences (SMHS) and director of the GW Institute for Neuroscience, along with post-doctoral fellow Daniel Meechan, Ph.D. and Thomas Maynard, Ph.D., associate research professor of pharmacology and physiology at GW SMHS, authored the study titled "Cxcr4 regulation of interneuron migration is disrupted in 22q11.2 deletion syndrome." http://medicalxpress.com/news/2013-01-gw-professor-autism-genetics.html Autism spectrum disorders Thu, 03 Jan 2013 12:41:30 EST news276439274 UC Davis researchers have found that for children with the genetic disorder known as chromosome 22q11.2 deletion syndrome anxiety—but not intelligence—is linked to poorer adaptive behaviors, such as self-care and communication skills, that affect daily life. The developmental syndrome, which is associated with a constellation of physical, cognitive and psychiatric problems, usually is apparent at birth or early childhood, and leads to lifelong challenges. http://medicalxpress.com/news/2012-11-higher-anxiety-poorer-functioning-children.html Pediatrics Mon, 05 Nov 2012 16:27:09 EST news271355219 Scientists studying a rare genetic disorder have identified a molecular pathway that may play a role in schizophrenia, according to new research in the October 10 issue of The Journal of Neuroscience. The findings may one day guide researchers to new treatment options for people with schizophrenia—a devastating disease that affects approximately 1 percent of the world's population. http://medicalxpress.com/news/2012-10-rare-genetic-disorder-molecules-role.html Genetics Tue, 09 Oct 2012 17:00:01 EST news269020708 In an important test of one of the first drugs to target core symptoms of autism, researchers at Mount Sinai School of Medicine are undertaking a pilot clinical trial to evaluate insulin-like growth factor (IGF-1) in children who have SHANK3 deficiency (also known as 22q13 Deletion Syndrome or Phelan-McDermid Syndrome), a known cause of autism spectrum disorder (ASD). http://medicalxpress.com/news/2012-04-clinical-drug-subtype-autism.html Autism spectrum disorders Tue, 24 Apr 2012 14:47:17 EST news254497462 11 May 2011 - Two new research studies published in Biological Psychiatry point to progressive abnormalities in brain development that emerge as vulnerable individuals develop schizophrenia. http://medicalxpress.com/news/2011-05-brain-track-vulnerable-individuals-schizophrenia.html Psychology & Psychiatry Wed, 11 May 2011 10:31:25 EST news224328659
