RESEARCHGenes' Role In Autism A Complicated Connection ". . .New study only explains about 3% of autism cases — and, taken together with previous studies, researchers say they can only find a convincing genetic cause in less than 15% of all cases of autism." EDITOR'S NOTE: Although there is ample coverage of genetic research and autism in the media lately, most of it reports on the same studies. This is some additional reporting worth noting. By Leigh Mascarelli, Special to the Los Angeles Times xrl.in/5nof

Though scientists know genetic factors play a part in the array of autism disorders, the vast number of genes involved, plus possible environmental considerations, make narrowing the cause a vastly difficult goal. Though the causes of autism are unclear, and many researchers believe that environmental factors play some kind of role, they are sure of one

thing: Genes are strongly involved. Scientists once harbored hopes that autism might be linked to a handful of genetic mutations that would clearly explain why someone develops it. But the genetic roots of autism (known these days as autism spectrum disorders because behaviors and severity differ widely) are proving much trickier to untangle than anticipated. One problem is that the number of people in most studies has been limited; another is that the small tweaks in genes that scientists have linked to autism so far are very rare in the human population. Nonetheless, as new techniques make it easier to inspect the human

genome in fine detail, researchers are uncovering a dizzying array of genes that play a role in autism in different people. Clues to the biological processes affected by these genes are beginning to emerge — and some offer hope for one day reversing the symptoms of this range of related disorders. So far, scientists know this much: Autism is linked to different genes in different people, and multiple genes could be involved in each person. These genetic factors, in turn, interplay with environmental ones — possibly ones a fetus is exposed to in the womb — but researchers don't yet For rest of today's SAR click here:www.sarnet.org/frm/forsar.htm
