Abstract

BACKGROUND:

Abdominal aortic aneurysm (AAA) is a complex disorder in which environmental and genetic factors play a role in pathogenesis. Linkage to 2 adjacent loci on 19q13 in familiar AAA was previously demonstrated. We studied whether genetic variation within these regions predisposes to AAA.

METHODS:

Common genetic variants in the described regions on 19q13 were analyzed using tag single nucleotide polymorphisms (SNPs) in a Dutch case-control population. Single nucleotide polymorphism genotyping was performed in a 2-stage approach.

RESULTS:

In stage 1, 615 SNPs were genotyped in 376 AAA patients and 648 controls. In stage 2, 8 SNPs of stage 1 with a P value < .015 were genotyped in a second independent cohort of 360 cases and 376 controls. No differences in allele frequencies were observed.

CONCLUSION:

Our findings suggest that there are no common AAA predisposing SNPs within the 19q13 loci. Hence, the genetic basis of familiar and sporadic AAA may differ.
