To test this hypothesis, we investigated the interaction between tagging polymorphisms in the<jats:italic>UCP2<\/jats:italic>gene (rs2306819, rs599277 and rs659366), alcohol intake and obesity traits such as BMI and waist circumference (WC) on alanine aminotransferase (ALT) and gamma glutamyl transferase (GGT) in a large meta-analysis of data sets from three populations (<jats:italic>n<\/jats:italic>=20\u200a242).<\/jats:p><\/jats:sec><jats:sec><jats:title>Design and methods<\/jats:title><jats:p>The study populations included the Northern Finland Birth Cohort 1966 (<jats:italic>n<\/jats:italic>=4996), Netherlands Study of Depression and Anxiety (<jats:italic>n<\/jats:italic>=1883) and LifeLines Cohort Study (<jats:italic>n<\/jats:italic>=13\u200a363).
