Although the circular-RNA layer remains less explored in the A-T context, individual mechanistic studies, in context of some other diseases, already found circATM in abdominal aortic aneurysms as modulators of oxidative stress and circ_0008657 when binds with miR-203-a-3p activates ATM to regulate the DNA-damage signaling [31, 35]. The gene discussed is ATM; the disease is abdominal aortic aneurysm.
