that's good news SN 
.
A genetic link and/or pre-disposition for epilepsy was found recently too ( a few members of my family have epilepsy and I have always firmly believe that for us there is some genetic weekness.
Autism Spectrum Disorder takes many forms .That test may show a genetic 'risk'..though it perhaps wouldn't be, as the article below says 'The Holy Grail' .,
There is perhaps a chance that in some cases that an environmental factor or trigger may be needed along side the genetic signature ?
Maybe until or unless immunisation is ruled out as a trigger in those with that genetic signature perhaps some will believe that that is a possibilty ?
this is the last part of the article :
Genetic 'signature' highlights autism risk
'Holy grail'
Professor Sylvia Rodger, CEO of Australia's Autism CRC says many people have been trying to find a genetic signature for autism.
"The holy grail of autism research has been trying to find a genetic signature. It has been elusive. Eric's work has been very very important and continues to be, so we're all interested to listen to the latest he has to say," she says.
But, warns Rodger, an accurate diagnosis of autism risk is a tricky business.
"It's not like Down syndrome where there is a single chromosome mutation. We're looking at a signature of multiple genetic combinations and it's very very complex."
She says the CRC is using a unique approach combining genetic, biological and behavioural work, and will potentially have a "genetic chip" that could enable early identification of autism risk.
Professor Cheryl Dissanayake, director of the Olga Tennison Autism Research Centre, is a psychologist interested in diagnosing risk of autism in children under two years old.
She emphasises environmental factors also play a role, and early behavioural signs need to be combined with genetic signatures for an accurate diagnosis of autism risk.
Dissanayake, who is involved in the Autism CRC, says autism covers such a diverse range of conditions.
"We need to be very careful about thinking we're going to have a silver bullet if we find some gene network," she says. "It might identify some of the subgroups but not all of them."
