Table 1 summarizes the sample groups, and Supplementary Table S1 lists more detailed information about each donor. There were no statistically significant differences in gene expression with respect to AAA diagnosis, age, or smoking. However, there was a trend for CNN2 to have lower expression, and SERPINB9 to have higher expression in the AAA than control samples (Figure 2). Here, SERPINB9 is linked to triple-A syndrome.
