Neurobehavior related to epigenetic differences in preterm infants


Preterm birth is associated with medical problems affecting the neuroendocrine system, altering cortisol levels resulting in negative effects on newborn neurobehavior. Newborn neurobehavior is regulated by DNA methylation of NR3C1 and HSD11B2. Aim: Determine if methylation of HSD11B2 and NR3C1 is associated with neurobehavioral profiles in preterm infants. Patients & methods: Neurobehavior was measured before discharge from the hospital in 67 preterm infants. Cheek swabs were collected for DNA extraction.
