A study carried out by US researcher’s claims that a genetic testing method called chromosomal microarray analysis (CMA), is three times better than the two tests that are currently used to detect genetic variants related to autism.

They believe that chromosomal microarray analysis or CMA, is more accurate in the first round of tests, to detect genetic variants for a child having autism.

Study Co-author Dr. David Miller, of Children's Hospital, Boston's Division of Genetics, said in a statement, “CMA clearly detects more abnormalities than other genetic tests that have been the standard of care for many years”. Dr. Miller said that he hopes that the evidence will be a step forward to convince insurance companies to recognize this testing.

Autism is a serious condition that 1 in 110 children in the United States suffer from. Ranging from mild Asperger's syndrome to social disability and severe mental retardation, scientists all over the world have still not been able to find a cure for Autism.

Andy Shih, who is the Vice President for Scientific Affairs for Autism Speaks, an autism advocacy organization that funds researches to find a cure for this disease, says that the real utility of this test is not clear in actual clinical settings.

“Until we know more about the association between some of these variants and actual autism risk, it’s difficult to see how this could benefit the family now”, Shih said.
