It does not appear that, in the near future, individual investigators will be able to increase their own sample sizes to levels sufficient to carry out highly powered association studies within the various forms of epilepsy.[60] The following pertinent lessons could be learned from the lack of consistency in the results from different studies on ABCB1 polymorphisms on drug resistance: first, the field must concentrate more seriously on efforts to determine which polymorphisms have real effects, as opposed to always racing to publish a new association. The gene discussed is ABCB1; the disease is epilepsy.
