Owing to the relatively early decreasing trend of m6A levels of Ate1 and Fgf22 mRNAs along with time, they might be suitable for the detection of early stage of acute radiation syndrome (ARS) which are capable of gauging absorbed radiation dose at a dose range of 1 to 6.5 Gy within 3 days post-irradiation. The gene discussed is ATE1; the disease is Axenfeld-Rieger syndrome.
