Abstract |
Abdominal aortic aneurysm (AAA) has a multifactorial aetiology and the importance of genetic components is getting increasing interest. Alteration in the structure of the vascular extracellular matrix has been described in AAA. Matrix metalloproteinases (MMPs) degrade extracellular matrix proteins which alter the vessel wall stability. We evaluated two different polymorphisms, a CA repeat and a cytosine to thymidine transition in the promoter sequence of MMP-9 gene for frequency in 146 patients with AAA. We compared the results with those of 156healthy subjects. No difference was found in the allelic distribution of either polymorphisms. We therefore found no evidence that MMP-9 is a marker of susceptibility for AAA.
