Background: Abdominal aortic aneurysm (AAA) has a multifactorial etiology and the relevance of genetic factors is getting increasing interest, in particular those related to the destructive remodeling of extracellular matrix.
Methods: We performed a candidate gene association study of polymorphisms in genes coding matrix metalloproteinases (MMPs), tissue inhibitors of MMPs (TIMPs), and elastin (ELN) in AAA. DNA samples from 423 AAA patients and 423 controls were genotyped for 12 polymorphisms in 10 genes: MMP1 (-1607G/GG), MMP2 (-735C/T; -1306C/T; -1575 G/A), MMP3 (5A/6A), MMP9 (-1562C/T), MMP10 (A180G), MMP-12 (-82A/G), MMP-13 (-77A/G), TIMP1 (C434T), TIMP3 (-1296T/C), and ELN (G1355A).
