Overview
Laboratory Findings
Clinical genetics evaluations are often done once ASD is diagnosed, particularly when other symptoms already suggest a genetic cause. Although genetic technology allows clinical geneticists to link an estimated 40% of cases to genetic causes,[1] consensus guidelines in the U.S. and UK are limited to high-resolution chromosome and fragile X testing.[2] As new genetic tests are developed several ethical, legal, and social issues will emerge. Commercial availability of tests may precede adequate understanding of how to use test results, given the complexity of autism's genetics.[3] Metabolic and neuroimaging tests are sometimes helpful, but are not routine.[2]
