When prospective parents have trouble conceiving and decide to seek medical help, they typically experience more than a little anxiety and have a host of questions: What are the potential risks to the mother and the baby? What kinds of diseases or other problems are associated with assisted reproduction? And, is one of those problems autism? As many as one in every 50 children age 6 to 17 is identified as having autism spectrum disorder, which impairs social interaction and communication. The increasing prevalence of autism has boosted the desire to pinpoint causes, and everything from parents' ages to vaccination has come under scrutiny by researchers looking for a link. Over the past five years, several studies have focused on infertility treatment, partly because of the coincidental rise in both the diagnosis of autism and the use of assisted reproduction, says Sean Ackerman, M.D., a child psychiatry fellow at Fletcher Allen Health Care and clinical instructor in psychiatry at the University of Vermont College of Medicine. "People are always looking for that silver bullet with autism," he said. Ackerman and his team found no such link when they studied previously collected DNA data from almost 2,000 children with autism to … Continue reading →

Contact Information Available for logged-in reporters only Newswise PHILADELPHIA Using a zebrafish model of a human genetic disease called neurofibromatosis (NF1), a team from the Perelman School of Medicine at the University of Pennsylvania has found that the learning and memory components of the disorder are distinct features that will likely need different treatment approaches. They published their results this month in Cell Reports. NF1 is one of the most common inherited neurological disorders, affecting about one in 3,000 people. It is characterized by tumors, attention deficits, and learning problems. Most people with NF1 have symptoms before the age of 10. Therapies target Ras, a protein family that guides cell proliferation. The NF1 gene encodes neurofibromin, a very large protein with a small domain involved in Ras regulation. Unexpectedly, the Penn team showed that some of the behavioral defects in mutant fish are not related to abnormal Ras, but can be corrected by drugs that affect another signaling pathway controlled by the small molecule cAMP. They used the zebrafish model of NF1 to show that memory defects such as the recall of a learned task -- can be corrected by drugs that target Ras, while learning deficits are corrected by … Continue reading →
