Grandparents may transmit autism risk to grandchildren

According to researchers the risk of rising autism may be passed on through and not just too future generations. The global study suggests older fathers are more likely to have grandchildren with autism than their younger counterparts. The mechanism is undecided but it is thought they may transmit silent mutations to their grandchildren. But experts have urged carefulness; stressing autism is the result of many different factors.
The study, looking at almost 6,000 people with the condition, is published in the journal Jama psychoanalysis. Using national databases from Sweden they studied almost 6,000 people diagnosed with the state and more than 30,000 without, tracking their parents' and grandparents' ages. According to the National Autistic Society, more than one in every 100 people in the UK has the condition. However the team of UK, Swedish and Australian researchers says this is one of the first pieces of facts to show the risk can be passed on through -rather than just directly to s future generations.
