The Claim
The CACNA2D1 gene exhibits cis-regulation in the mouse eye, with expression levels varying by up to 5.6-fold between strains due to parental haplotype differences, and this variation is strongly associated with age-dependent differences in 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.
In mice, differences in the CACNA2D1 gene's activity between genetic strains correlate with changes in eye pressure that occur with aging.
See the scientific wording
The CACNA2D1 gene is cis-regulated in the mouse eye, with expression levels differing by up to 5.6-fold between strains based on parental haplotype, and this variation is strongly associated with age-dependent intraocular pressure differences.
The version of the CACNA2D1 gene a mouse inherits determines how much of the protein is made in the eye. More protein means more calcium enters certain eye cells, which increases fluid production and tightens drainage pathways, raising eye pressure. Less protein means less calcium, less fluid, and easier drainage, lowering eye pressure. This difference grows as the mouse ages.
What the research says
1 studyIn mice, the version of the CACNA2D1 gene they inherit affects how much of the protein is made in the eye, and this changes how much pressure builds up inside the eye as they get older. A drug that targets this protein only works well in mice with one version of the gene.
