Although rs505922 was not associated with LAA stroke (TT genotype, adjusted OR = 1.32; 95 % CI, 0.94 to 1.87), two novel SNPs, rs8176668 (AT genotype, adjusted OR = 0.71; 95 % CI, 0.55 to 0.92) and rs2073824 (AA genotype, adjusted OR = 0.72; 95 % CI, 0.57 to 0.92), were associated with LAA stroke.
Independent replication in Meta-Stroke confirmed the rs505922 association with stroke, beta (standard error, SE) = 0.066 (0.02), p = 0.001, a finding specific to large-vessel and cardioembolic stroke (p = 0.001 and p = < 0.001, respectively) but not seen with small-vessel stroke (p = 0.811).
