PURPOSE: Hypoxic-ischemic encephalopathy (HIE) remains the major cause of cerebral palsy and epilepsy in developed countries. Hypoxia-inducible factor 1 alpha (HIF-1α) is the key mediator of oxygen homoeostasis. The aim of this study was to investigate whether hypoxia-inducible factor 1 subunit alpha (HIF1A) functional polymorphisms are associated with the risk of epilepsy, drug-resistant epilepsy, and cerebral palsy after neonatal HIE.
METHODS: The study included 139 healthy controls and 229 patients with epilepsy and/or cerebral palsy, of which 95 had perinatal HIE. Genomic DNA isolated from buccal swabs or peripheral blood were genotyped for HIF1A rs11549465 and rs11549467 using PCR based methods.
RESULTS: The investigated HIF1A polymorphisms did not influence the risk of epilepsy and its drug-resistance nor cerebral palsy after neonatal HIE (all p > 0.05). Clinical characteristics of patients were significantly associated with neurological deficits after HIE.
CONCLUSION: This study found no statistically significant association of HIF1A rs11549465 and rs11549467 with the development of epilepsy and its drug-resistance, as well as cerebral palsy, after neonatal HIE.
