Forkhead box C1 (FOXC1), a member of the FOX protein family, is a key regulator of the development of the anterior chamber angle, and its abnormal expression correlates highly with the incidence of congenital glaucoma (Chen et al., 2016; Golson and Kaestner, 2016; Deng et al., 2017; Ramezani et al., 2019). This evidence concerns the gene FOXC1 and congenital glaucoma.
