As mentioned above, two studies investigated the association in Caucasian,[9,16] others investigated the association between CDKN2BAS polymorphisms and intracranial aneurysm in Asian population.[2,3,12] As shown in Figure 4, the results of the association were still stable in subgroups (Asian: OR, 1.24; 95% CI, 1.13–1.35; P < .001; Caucasian: OR, 1.35; 95% CI, 1.26–1.44; P < .001). The gene discussed is CDKN2B-AS1; the disease is Dilatation of the cerebral artery.
