Transcript

Genetic testing is very good for Friedrich’s ataxia. And so I think it ought to be relied on very early in the process.

I think if there is clinical suspicion of Friedrich’s ataxia, as soon as there is clinical suspicion, a gene test is appropriate. That would be in balance along with clinical findings by the provider that are suggestive of Friedrich’s ataxia — for instance, lack of reflexes, decreased vibration or joint position sense, so-called dorsal column function. Certainly somebody with a family history, like a brother or sister who’s already been diagnosed, as soon as there seems to be some abnormalities in balance, that would be a good time to send genetic testing.

There’s really no reason to wait on that. If it’s in the differential, it can be ruled out with a genetic test quite easily or ruled in with a positive test. And so that ought to be sent quickly.
