Is there a genetic test that can help with knowing if your child will have a learning problem?

Depends on issue: There are a variety of chromasomal markers now available to confirm problems like fragile x, and other names symdromes where learning problems are common.Some newer marker are associated with autism & autism spectrim disorder that may help explain some of their learning problems. However, i know of no test that would accurately predict any specific learning disorder as the child got older.

Not Specifically: There are no genetic tests that are specifically for learning disorders. However, problems with learning, and difficulties with mental retardation, are seen in some genetic disorders for which there are chromosomal tests. For the large majority of kids with learning problems, these genetic tests will not reveal an explanation of the problem.
