Genome-wideassociation studies have identified several single nucleotide polymorphisms (SNPs)associated with sporadic hemorrhagic strokes, including APOE(19q13), SLC25A44 (1q22), COL4A1 (13q34) andKCNK17 (6p21) (Lindgren, 2014; Rost et al.,2008). This evidence concerns the gene APOE and hemorrhagic stroke.
