Autism risk rises for siblings of autistic children

YOUNGER siblings of children with autism are more likely than previously thought to develop the condition themselves, according to a study backed by New <a href="http://wk.putianb2b.com/"><strong>网赚之家 </strong></a> York-based charity Autism Speaks. Sally Ozonoff at the University of California, Davis, studied 664 infants in families that already contain <a href="http://wk.putianb2b.com/"><strong>威客兼职 </strong></a> at least one child with autism. Her team concluded that the infants were 19 per cent more likely than usual to develop the condition - almost double the previous elevated-risk estimate of 3 to 10 per cent (Pediatrics, DOI: 10.1542/peds.2010-2825). Rosa Hoekstra of the Open University in Milton Keynes, UK, says it is possible that younger siblings learn autism-like behaviours from their elders. But the latest study in families with more than one autistic child <a href="http://wk.putianb2b.com/"><strong>网络兼职工作 </strong></a> suggests genetics plays a bigger role than the environment.
