The Claim

Genetic variation in the CACNA2D1 gene influences intraocular pressure through modulation of calcium channels, as the CACNA2D1 gene is expressed in ocular tissues involved in aqueous humor dynamics and its protein product is the target of pregabalin.

How it works
1 study reviewed
In plain English

Variations in the CACNA2D1 gene are associated with changes in intraocular pressure due to the gene's role in calcium channel function in eye tissues that regulate fluid drainage.

See the scientific wording

The CACNA2D1 gene is expressed in ocular tissues involved in aqueous humor dynamics, and its protein product is the target of pregabalin, suggesting a plausible biological pathway by which genetic variation in this gene may influence intraocular pressure through calcium channel modulation.

Why this might work

A gene called CACNA2D1 makes a part of a calcium channel in the eye that controls fluid pressure. When a drug binds to this part, it blocks calcium from entering cells in the fluid-producing and fluid-draining areas of the eye. Less calcium makes the fluid-producing cells secrete less fluid and the fluid-draining cells open up, which lowers the pressure inside the eye. People with certain versions of this gene have more of this channel, so the drug works better in them.

  1. Study: Systems genetics identifies a role for Cacna2d1 regulation in elevated intraocular pressure and glaucoma susceptibility

    The study found that a gene called CACNA2D1 is active in parts of the eye that control fluid pressure, and a drug called pregabalin that targets this gene can lower eye pressure—but only in some mice with certain versions of the gene. This means changes in this gene might affect eye pressure by changing how calcium moves in eye cells.
