Whole exome sequencing results of a primary angle closure glaucoma (PACG)-enriched family indicated a higher variant frequency of a single-nucleotide variant of GTPBP3 than that in control samples, demonstrating that glaucoma should be one among the oxidative phosphorylation diseases and may be affected by GTPBP3 (Qiao et al. 2020). This evidence concerns the gene GTPBP3 and glaucoma.
