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.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
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.
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.
What the research says
1 studyPeople 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.
