DGKG and open-angle glaucoma: DGKG, diacylglycerol kinase gamma, whose retina-specific eQTL colocalized (CLPP = 0.96) with POAG cross-ancestry association (Fig. 8f) displayed the strongest astrocyte-specificity in ONH (Fig. 8d) and retina (Supplementary Fig. 16d), compared to all other astrocyte-specific POAG-colocalizing e/sGenes.
