Mutations in the receptor genes of the transforming growth factor β pathway, TGFBR1 and TGFBR2, cause syndromes with thoracic aortic aneurysms, while genetic variants in TGFBR1 and TGFBR2 are associated with abdominal aortic aneurysms.
The aim of this study was to assess the association of single nucleotide polymorphisms (SNPs) within TGFBR1 and TGFBR2 with AAA and infrarenal aortic diameter by combining data from previously published studies.
This study, which demonstrates an interaction between ACE and TGFBR1 genes in predisposing to AAA, may provide further information on the mechanisms contributing to AAA susceptibility, and offer a topic for future larger studies.
This study examined the possible association between TGF-beta receptor 1 and 2 (TGFBR-1 and -2) single nucleotide polymorphisms (SNPs) and serum TGF-beta1 with AAA.
