Whereas the specific molecular and cellular functions of FAM102A family proteins are unknown, FAM102A mutations have been implicated in the progression of glaucoma (Khor et al., 2016; Li et al., 2020; Nongpiur et al., 2018; Shi et al., 2021; Zhuang et al., 2018). This evidence concerns the gene EEIG1 and glaucoma.
