SIX1 rs10760130: What Your Genotype Means
The rs10760130 variant is a genetic marker located near the SIX1 gene, which is involved in developmental processes. Research has identified this variant as being statistically associated with variations in the vertical cup-to-disc ratio, a clinical measurement used in assessing risk for primary open-angle glaucoma.
What each genotype means
Baseline glaucoma risk
This genotype is associated with the baseline risk profile for vertical cup-to-disc ratio and primary open-angle glaucoma within the SIX1/SIX6 gene cluster. Research indicates this variant is part of a regulatory region, and individuals with this genotype should continue routine eye health screenings as recommended by their eye care professional.
This genotype is common in many populations, though exact frequencies vary by ancestry.
Intermediate glaucoma risk
This genotype represents a heterozygous state for a regulatory variant in the SIX1/SIX6 gene cluster. Studies suggest this locus is associated with variations in optic disc structure and primary open-angle glaucoma risk, though the clinical impact for an individual is modest. Regular monitoring of eye health and intraocular pressure is advised.
This genotype is frequently observed in European populations, where the minor allele frequency is approximately 0.40.
Elevated glaucoma risk
This genotype is associated with a higher statistical likelihood of variations in the vertical cup-to-disc ratio, a trait linked to primary open-angle glaucoma risk. While this association is supported by large-scale genomic studies, it is not a diagnostic indicator of disease. Please discuss your eye health history and screening needs with your ophthalmologist.
This genotype is common, appearing in a significant portion of the population across various ancestries.
Understanding the rs10760130 Variant
The rs10760130 variant is a single nucleotide polymorphism (SNP) located on chromosome 14. In the context of human genetics, a SNP represents a variation at a single position in the DNA sequence among individuals. This specific variant is situated within a genomic region containing the SIX1 and SIX6 homeobox gene cluster. Scientists study such variants to understand how subtle differences in our genetic code might influence physical traits or susceptibility to certain conditions. It is important to note that rs10760130 is a regulatory variant, meaning it is thought to influence how nearby genes are expressed rather than directly altering the structure of a protein. Because it is located in a non-coding region, its primary function is likely related to the control of gene activity during development or in specific tissues.
The Role of the SIX1 Gene
The SIX1 gene encodes a homeodomain-containing transcription factor, which is a type of protein that binds to DNA to regulate the activity of other genes. These proteins are essential for orchestrating complex developmental processes, including organogenesis and tissue-specific growth. While the SIX1 gene is well-known for its critical role in embryonic development—where mutations can lead to conditions like branchiootic syndrome or hereditary deafness—its function in the adult eye is also a subject of ongoing scientific interest. By acting as a molecular switch, SIX1 helps ensure that cells develop and function correctly in various parts of the body. In the context of the eye, researchers are investigating how the regulation of this gene cluster might influence the structural characteristics of the optic nerve head, which is a key area of focus in glaucoma research.
Research Associations and Evidence Strength
Large-scale genome-wide association studies (GWAS) have identified a statistical link between rs10760130 and the vertical cup-to-disc ratio. The cup-to-disc ratio is a clinical measurement used by eye care professionals to evaluate the health of the optic nerve; a larger ratio can sometimes be an indicator of increased risk for primary open-angle glaucoma. While these associations are statistically significant in large population cohorts, the evidence strength for this specific variant remains limited in terms of clinical utility. It is crucial to understand that a statistical association does not imply a direct cause-and-effect relationship. Many genetic and environmental factors contribute to eye health, and this variant is only one small piece of a much larger, complex puzzle. Current research continues to explore how these genetic signals translate into biological outcomes, but the findings are not currently used for individual diagnostic purposes.
Population Frequency
The rs10760130 variant is relatively common in human populations. Data from large-scale genomic databases indicate that the minor allele frequency is approximately 0.40 to 0.45 in European populations. This means that a significant portion of the population carries at least one copy of the variant allele. Because it is so common, it is considered a normal variation within the human genome rather than a rare mutation. The frequency can vary across different ancestral groups, which is a common observation in genetic studies. Understanding these frequencies helps researchers determine whether a variant is likely to have a broad impact on a trait or if its effects are restricted to specific populations. As with many common variants, the presence of the allele is widespread and does not inherently indicate the presence of a disease or a medical condition.
What This Information Means for You
If you have received information about your rs10760130 genotype, it is important to view it in the proper context. This variant is a tool for scientific research, not a diagnostic test for glaucoma or any other eye condition. Genetic associations are based on population-level data and cannot predict an individual's health outcome. You cannot change your genotype, and having a specific version of this SNP does not mean you will develop a particular trait. If you have concerns about your eye health, such as changes in your vision or a family history of glaucoma, the most effective step is to schedule a comprehensive eye examination with an ophthalmologist or optometrist. They can perform clinical assessments that are far more accurate and relevant to your personal health than any single genetic marker. Always rely on professional medical advice rather than genetic data for managing your health.
How common is this variant?

Frequently asked questions
Does having the rs10760130 variant mean I have glaucoma?
No. This variant is only associated with a statistical trend in optic disc measurements in large studies. It is not a diagnostic test for glaucoma, and having the variant does not mean you have or will develop the condition.
Can I use this genetic information to prevent eye disease?
Genetic information for this variant is not currently used for clinical prevention. The best way to maintain eye health is to have regular check-ups with an eye care professional who can monitor your actual eye structure and function.
Why is this variant associated with the SIX1 gene?
The variant is located in a regulatory region near the SIX1/SIX6 gene cluster. Researchers believe it may influence how these genes are expressed, which is why it is studied in relation to developmental traits.
Is this variant rare?
No, this variant is quite common in the population. It is considered a normal genetic variation that is present in a large percentage of healthy individuals.
