SULT1A1*1/*2 (638g > A) influence on the sulfation of fulvestrant (4A) and β-naphthol (4B). Enzymatic activity was determined either colorimetrically (for β-naphthol) or by Lc-Ms/Ms. genotype–phenotype relationships were assessed by analysis of variance with phenotype as the dependent variable.
Abbreviation: Lc-Ms/Ms, liquid chromatography–mass spectrometry/tandem mass spectrometry.
