Here, we found that the rs9884978 GA/AA genotypes were significantly associated with the increase of METTL14 expression in cultured fibroblasts and adrenal glands (Figures 1A, B), suggesting that the protection role of rs9884978 GA/AA genotypes may be positively linked to the increase of METTL14 mRNA level in endometriosis. Here, METTL14 is linked to endometriosis.
