The rs197388 variant in GEMIN3 has been associated with primary open-angle glaucoma in the Polish population (Molasy et al., 2018), idiopathic azoospermia in a Turkish population (Ozlem et al., 2017), and increased risk of oropharyngeal squamous cell carcinoma (Chen et al., 2016). This evidence concerns the gene DDX20 and glaucoma.
