      Lee, Yunsung; Løkås Haftorn, Kristine; Denault, William Robert Paul; Nustad, Haakon Egdetveit; Page, Christian; Moen, Gunn-Helen; Magnus, Maria C.; Gjessing, Håkon K.; Harris, Jennifer R.; Magnus, Per; Håberg, Siri E.; Jugessur, Astanand; Bohlin, Jon; Lyle, Robert; Lee-Ødegård, Sindre; Groop, Leif C.; Prasad, Rashmi B.; Sletner, Line; Sommer, Christine (Journal article; Peer reviewed, 2020)
      Background Epigenetic clocks have been recognized for their precise prediction of chronological age, age-related diseases, and all-cause mortality. Existing epigenetic clocks are based on CpGs from the Illumina ...
    • An EPIC predictor of gestational age and its application to newborns conceived by assisted reproductive technologies 

      Haftorn, Kristine Løkås; Lee, Yunsung; Denault, William Robert Paul; Page, Christian Magnus; Nustad, Haakon Egdetveit; Lyle, Robert; Gjessing, Håkon Kristian; Malmberg, Anni; Magnus, Maria Christine; Næss, Øyvind; Czamara, Darina; Räikkönen, Katri; Lahti, Jari; Magnus, Per Minor; Håberg, Siri Eldevik; Jugessur, Astanand; Bohlin, Jon (Journal article; Peer reviewed, 2021)
      Background: Gestational age is a useful proxy for assessing developmental maturity, but correct estimation of gestational age is difficult using clinical measures. DNA methylation at birth has proven to be an accurate ...
    • Maternal BMI at the start of pregnancy and offspring epigenome-wide DNA methylation: findings from the pregnancy and childhood epigenetics (PACE) consortium 

      Sharp, Gemma C; Salas, Lucas A; Monnereau, Claire; Bohlin, Jon; Page, Christian; Lie, Rolv T.; Magnus, Maria Christine; Munthe-Kaas, Monica Cheng; Nystad, Wenche (Peer reviewed; Journal article, 2017-10)
      Pre-pregnancy maternal obesity is associated with adverse offspring outcomes at birth and later in life. Individual studies have shown that epigenetic modifications such as DNA methylation could contribute. Within the ...
    • Maternal plasma folate impacts differential DNA methylation in an epigenome-wide meta-analysis of newborns 

      Joubert, Bonnie R; Den Dekker, Herman T; Felix, Janine F; Bohlin, Jon; Ligthart, Symen; Beckett, Emma; Tiemeier, Henning; van Meurs, Joyce B; Uitterlinden, Andre G; Hofman, Albert; Håberg, Siri Eldevik; Reese, Sarah E; Peters, Marjolein J; Kulle Andreassen, Bettina; Steegers, Eric A P; Nilsen, Roy Miodini; Vollset, Stein Emil; Midttun, Øivind; Ueland, Per Magne; Franco, Oscar H; Dehghan, Abbas; De Jongste, Johan C; Wu, Michael C; Wang, Tianyuan; Peddada, Shyamal D; Jaddoe, Vincent W V; Nystad, Wenche; Duijts, Liesbeth; London, Stephanie J (Peer reviewed; Journal article, 2016-02-10)
      Folate is vital for fetal development. Periconceptional folic acid supplementation and food fortification are recommended to prevent neural tube defects. Mechanisms whereby periconceptional folate influences normal development ...
    • Matrilineal diversity and population history of Norwegians 

      Kristjansson, Dana; Bohlin, Jon; Jugessur, Astanand; Schurr, Theodore G. (Journal article; Peer reviewed, 2021)
      Background While well known for its Viking past, Norway's population history and the influences that have shaped its genetic diversity are less well understood. This is particularly true with respect to its demography, ...
    • Placental epigenetic clocks: estimating gestational age using placental DNA methylation levels 

      Lee, Yunsung; Choufani, Sanaa; Weksberg, Rosanna; Wilson, Samantha L.; Yuan, Victor; Burt, Amber; Marsit, Carmen; Lu, Ake T.; Ritz, Beate; Bohlin, Jon; Gjessing, Håkon K.; Harris, Jennifer Ruth; Magnus, Per; Binder, Alexandra M.; Robinson, Wendy P.; Jugessur, Astanand; Horvath, Steve (Peer reviewed; Journal article, 2019)
      The human pan-tissue epigenetic clock is widely used for estimating age across the entire lifespan, but it does not lend itself well to estimating gestational age (GA) based on placental DNAm methylation (DNAm) data. We ...
