      Helgeland, Øyvind; Vaudel, Marc; Sole-Navais, Pol; Flatley, Christopher; Juodakis, Julius; Bacelis, Jonas; Koløen, Ingvild; Knudsen, Gun Peggy Strømstad; Johansson, Bente Berg; Magnus, Per Minor; Reichborn-Kjennerud, Ted; Juliusson, Pétur Benedikt; Stoltenberg, Camilla; Holmen, Oddgeir Lingaas; Andreassen, Ole; Jacobsson, Bo; Njølstad, Pål Rasmus; Johansson, Stefan (Peer reviewed; Journal article, 2022)
      Early childhood obesity is a growing global concern; however, the role of common genetic variation on infant and child weight development is unclear. Here, we identify 46 loci associated with early childhood body mass index ...

      A well-functioning placenta is essential for fetal and maternal health throughout pregnancy. Using placental weight as a proxy for placental growth, we report genome-wide association analyses in the fetal (n = 65,405), ...
    • Genome-wide association study reveals dynamic role of genetic variation in infant and early childhood growth
