Based on the coexpression network of diagnostic genes and target miRNAs constructed in our study, hsa‐mir‐34a‐5p, hsa‐mir‐182‐5p, hsa‐mir‐129‐2‐3p, hsa‐mir‐1‐3p, hsa‐mir‐214‐3p, hsa‐mir‐374a‐5p, hsa‐let‐7d‐5p and hsa‐mir‐124‐3p were identified as common target miRNAs of ETS1 and ITPR3, suggesting their potential involvement in AAA pathology. Here, ITPR3 is linked to triple-A syndrome.
