A genetic test for autism currently classified as a secondary approach may be able to pick out the underlying causes for the condition at a rate more than three times that of a screening considered to be a first-tier test, according to a new study published in the journal Pediatrics Monday by the Autism Consortium and Children's Hospital Boston.
New tests allow you to see potential health problems in your DNA.Researchers launched the study to compare the newer screening, called chromosomal microarray analysis (CMA), against the tests that the American Academy of Pediatrics currently considers to be first-tier approaches -- G-banded karyotype and fragile X testing. They said they hope the new research will help the test achieve first-line status when it comes to determining the genetic reasons behind autism spectrum disorders.
