"WebTPMT plays a key role in the bioavailability of 6-TGN. High TPMT activity may lead to elevated levels of 6-MMP, which have been associated with hepatotoxicity (>5700 pmol/8 x 108 RBC) and refractoriness on therapy.9 A diminished TPMT activity will likely result in shunting 6-MP away from 6-MMP towards overproduction of 6-TGN.
