Tests

DNA testing for increases in the length of the CGG repeat area of the FMR1 gene is available. Testing is covered by Medicare when the person being tested has intellectual disability, ataxia, neurodegeneration, or premature ovarian failure which raises the possibility of an FMR1 pre-mutation or full mutation, or if the person has a relative with an FMR1 pre-mutation/full mutation.
