The Claim

Variants in the CACNA2D1 gene are associated with elevated intraocular pressure in mice and increased susceptibility to primary open angle glaucoma in humans, and higher expression levels of CACNA2D1 in the eye correlate with higher intraocular pressure.

In plain English

Specific changes in the CACNA2D1 gene are linked to higher eye pressure in mice and a greater risk of primary open angle glaucoma in humans, with more CACNA2D1 protein in the eye corresponding to higher pressure levels.

See the scientific wording

Variants in the CACNA2D1 gene are associated with elevated intraocular pressure in mice and increased susceptibility to primary open angle glaucoma in humans, with higher expression of CACNA2D1 in the eye correlating with higher pressure levels, suggesting this gene plays a role in regulating aqueous humor dynamics and glaucoma risk.

Why this might work

When the CACNA2D1 gene makes more of its protein in the eye, it causes more calcium to flow into cells that produce and drain fluid inside the eye. More calcium makes the fluid-producing cells create more fluid and the fluid-draining cells tighten up, so pressure builds up inside the eye.

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

    People and mice with certain versions of the CACNA2D1 gene have higher eye pressure, which raises their risk of glaucoma. The study found that this gene directly affects pressure levels, and a drug that targets it only works in those with specific gene versions.
