SCNN1A and glaucoma: Among the in silico identified new drug targets, i.e., genes or proteins not previously linked to glaucoma, we identified the following: SCNN1A (sodium channel epithelial 1 subunit alpha); CACNG3 (calcium voltage-gated channel auxiliary subunit gamma 3); PKD2 (polycystin 2, the transient receptor potential cation channel); SDC4 (syndecan 4, transmembrane heparan sulfate proteoglycan); and HP (haptoglobin).
