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.

In plain English

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.

Why this might work

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.

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

    In 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.
