Infants exposed to neonatal hyperglycaemia >10 mmol/L were more often males, had lower gestational age and weight z-score at birth, higher Clinical Risk Index for Babies (CRIB) score and were treated with steroids and mechanical ventilation for longer periods, and insulin-treated infants had lower gestational age at birth and higher prevalence of perinatal morbidities than non-treated infants with hyperglycaemia (table 1). The gene discussed is INS; the disease is Hyperglycemia.
