Abstract

Introduction. The common adiponutrin PNPLA3 variant p.Ile148Met is associated with liver injury. Here, we investigate the association of this polymorphism with hepatic and metabolic traits in a pediatric cohort. Patients and Methods. The study cohort comprised 142 German children age 5–9 years, 98 overweight, 19 children with NAFLD. Results. Overweight children presented with increased serum ALT and GGT activities. ALT activities differed significantly between carriers of different PNPLA3 genotypes in the entire study cohort, in normal weight children and in children younger than 7 years . Carriers of the prosteatotic PNPLA3 genotype p.148Met-Met displayed higher ALT activities as compared to children with the frequent genotype p.148Ile-Ile . The BMI was however a stronger predictor of ALT activities compared to the PNPLA3 genotype and , resp

The variant was associated with increased serum glucose levels and HOMA index in carriers of the p.148Ile-Met genotype but did not affect other metabolic traits or the presence of NAFLD. Discussion. The frequent PNPLA3 variant p.Ile148Met is associated with serum ALT activities already at a young age.
