Detailed Description:~Unrelated Korean subjects who have Spontaneous hemorrhagic stroke complicating severe eclampsia in pregnancy were recruited in the current study. Genotyping for various SNP associated due to the linkage disequilibrium patterns is to be performed. Genotypes would be statistically compared between patients with hemorrhagic stroke and normal control subjects free of hemorrhagic stroke
To search for a genetic marker of hemorrhagic stroke complicating severe eclampsia, a single nucleotide polymorphism (SNP) analysis of DNA obtained from the peripheral blood of patients with hemorrhagic stroke and normal control will be performed.
