If there is an autistic child or sibling or other family member, is there reason for gene testing the family?

4 doctors agree
In brief: Possibly
If there is a known genetic abnormality in the person with autism, then family members of child-bearing age may benefit.
Even if physical & neurological exam reveal no signs of a specific syndrome in a child with autism &/or intellectual disability, genetic microarray & dna probe for fragile x reveal an abnormality about 15% of the time. Evaluation by a geneticist is needed in those cases.

As of 9/2015 they are speculating a gene issue in more than 1/2 the cases.However, the type of gene testing is very specific ( as cited above)and not part of routine genetic studies.

In brief: No
Genetic testing would not provide any additional benefit in predicting who else would be at higher risk for autism.

In brief: Test the child first
Before testing family members, have the child tested.
there are many disorders that can present with autistic features. If an inheritable abnormality is found, then a discussion with a geneticist should be done to determine who might benefit from genetic testing.
