For SNPs that had previously been associated with AAA presence, meta-analysis of currently available data together with the two study cohorts disclosed positive associations for the MMP-3 rs3025058 (OR, 1.15; 95% CI, 1.06-1.25; P = .0009) and MTHFR rs1801133 (OR, 1.07; 95% CI, 1.02-1.12; P = .0088).
Results on 1258 cases and 1406 controls for MMP3 rs3025058 showed an association with AAA presence; best described by a dominant pattern of inheritance (OR=1.48 95%CI 1.23 - 1.78, p=3.95×10-5).
