Differential methylation and expression of genes related to inflammation (e.g., interleukin (IL)-10, IL-17) and oxidative stress (e.g., PON2, TP53INP1) have been linked to MFS aortic pathology. These alterations likely contribute to disease progression by influencing inflammatory responses, smooth muscle cell apoptosis, and biomechanical properties of the aorta. The transforming growth factor-beta (TGF-β) signaling pathway plays a central role in MFS pathology, with aberrant methylation of related genes potentially elevating active TGF-β levels and exacerbating aortic lesions.
