and endogenous compounds. Hence, coding region polymorphisms of UGT2B7 are
potentially of pharmacological, toxicological and physiological significance. Two variant
UGT2B7 cDNAs encoding enzymes with either His or Tyr at residue 268 have been isolated.
The variants, referred to as UGT2B7* 1 and UGT2B7* 2, respectively, arise from a C to T
transversion at nucleotide 802 of the UGT2B7 coding region. Analysis of genomic DNA from …
