Abstract excerpt
BACKGROUND: The inherited deficiency of thiopurine methyltransferase (TPMT) leads to severe myelosuppression in homozygous patients treated with thiopurine derivatives. One in 300 Caucasians has a homozygous TPMT deficiency with no measurable enzyme activity. To date, eight single-point mutations have been characterized; one group (TPMT*3) accounts for 75% of these. METHODS: We used four LightCycler(TM)...
