Finally, Milanowski et al. [75] investigated polymorphisms of MFN1 and MFN2 in the Polish population and showed that genotype GA of rs2111534 MFN1 polymorphism is a risk factor for HTG, while genotype AA of this polymorphism is protective against HTG, and genotype combinations of OPA1 and MFN2 are significantly associated with a higher or a lower risk of glaucoma. This evidence concerns the gene MFN1 and glaucoma.
