Similarly, CSF IFNγ concentrations were also significantly higher in the three HPHC groups than in controls, median and range: SBA: 35 (12–139) pg/ml; aqueduct stenosis: 22 (15–28) pg/mL; fetal intracranial haemorrhage: 22 (17–56) pg/mL; controls: 8 (8–22) pg/ml. The gene discussed is IFNG; the disease is intracranial hemorrhage.
