Toorell et al. demonstrated that cord blood NfL levels were higher in term newborns with intrapartum asphyxia and correlated with the severity of the insult based on the Apgar score at 5 minutes, arterial cord blood pH, and Sarnat clinical staging of hypoxic-ischemic encephalopathy [36]. The gene discussed is NEFL; the disease is perinatal asphyxia.
