A regional plot of the rs371331393 (stop-gained mutation, ARHGAP32, 11q24.3) variant’s position ± 500 kb shows associations with intracranial aneurysms in 250 patients and 294 controls after adjusting for age, sex, hypertension, diabetes, hyperlipidemia, cigarette smoking, and four principal components. The x- and y-axes indicate the chromosomal position (mega base, Mb) and -log10 transformed P-values, respectively. The purple diamond indicates the rs371331393 variant demonstrating the most significant association in our genome-wide association study (P = 9.3 × 10−27). The gray circles indicate other SNPs within 500 kb of the rs371331393 variant’s position.
