Glaucoma Risk: What Your DNA Says
Genetic variants affecting intraocular pressure and optic nerve resilience influence glaucoma susceptibility.
Physical traits like glaucoma risk arise from the combined action of dozens or hundreds of genetic variants, each contributing a small nudge. The variants analysed here are the ones with the clearest replicated associations, but they capture only part of the total heritable variation.
Key Genes Behind Glaucoma Risk
Scientists have identified specific genetic variants that influence glaucoma risk. While most traits are shaped by a combination of multiple genes and environmental factors, the following genes play particularly important roles:
MYOCCAV1TMCO1MYOCMYOC has been associated with glaucoma risk in genetic studies; as with most common variants, its individual effect is modest and works alongside many other genetic and non-genetic factors.
CAV1CAV1 has been associated with glaucoma risk in genetic studies; as with most common variants, its individual effect is modest and works alongside many other genetic and non-genetic factors.
TMCO1TMCO1 has been associated with glaucoma risk in genetic studies; as with most common variants, its individual effect is modest and works alongside many other genetic and non-genetic factors.
How Genetics Influence Glaucoma Risk
Your DNA contains instructions that shape glaucoma risk through variations in protein structure, enzyme activity, and gene expression levels. Small differences in your genetic code, known as single nucleotide polymorphisms (SNPs), can alter how your body develops and functions in ways that affect this trait.
For glaucoma risk, the interplay between genetic variants and environmental factors like diet, lifestyle, and exposure history determines your individual outcome. Some people carry variants that strongly push toward one expression of the trait, while others have a more balanced genetic profile where environment plays a larger role.
Genetic analysis provides insight into your predispositions, but does not guarantee a specific outcome. Traits are complex, and your unique combination of genetics and life experience shapes who you are.
How GenomeInsight Analyzes Glaucoma Risk
GenomeInsight examines your raw DNA data from services like 23andMe, AncestryDNA, or whole-genome sequencing (VCF files) to identify genetic variants linked to glaucoma risk. All analysis runs entirely in your browser, so your genetic data never leaves your device.
For each relevant SNP, GenomeInsight reports your genotype, the trait-associated alleles, published research findings, and how your genetic profile compares to the general population. Results are presented with clear visualizations and easy-to-understand explanations.
Frequently Asked Questions About Glaucoma Risk
Which genes influence glaucoma risk?
Glaucoma Risk has been linked to MYOC, CAV1, TMCO1 in genetic association studies. No single variant determines the trait — the analysis weighs all of these markers together against population reference data.
Is glaucoma risk purely genetic?
Only in part. Glaucoma Risk is heritable, meaning genetic differences account for some of the variation between people, but non-genetic factors — diet, habits, environment and randomness — play at least as large a role for most people.
What DNA data do I need for this result?
A raw genotype file from any major testing service (23andMe, AncestryDNA, MyHeritage, FamilyTreeDNA) covers these markers. Analysis happens entirely on your own device — nothing is uploaded to a server.
