SHISA2 and asthma: UPK1B is significantly associated with DNA methylation sites in whole blood of asthma patients, but the biological mechanism is unclear.[56] SHISA2, SNTG2, NAV3, and ITGA10 are new genes that have not been previously reported in ferroptosis and asthma, and their role in ferroptosis of asthmatic airway epithelial cells remains to be explored.
