rs3919995: Understanding This Intergenic Genetic Variant
The rs3919995 variant is a single nucleotide polymorphism located in an intergenic region of the human genome. It is documented in the GWAS Catalog as having potential associations with specific human traits, though current evidence remains limited.
What each genotype means
Limited evidence association
This genotype is documented in the GWAS Catalog as having potential associations with specific human traits, though the evidence remains limited. Because this variant is located in an intergenic region, its functional impact on nearby genes is not fully understood. Please note that genetic associations are statistical in nature and do not provide a medical diagnosis.
The frequency of this genotype varies significantly across different global populations and ancestral backgrounds.

What is rs3919995?
The rs3919995 variant is a specific location in the human genome where individuals may differ by a single DNA building block, or nucleotide. In genetics, this is known as a single nucleotide polymorphism, or SNP. This particular SNP is classified as intergenic, meaning it is situated in the vast stretches of DNA that lie between protein-coding genes. Because it does not sit within a gene, it does not directly provide instructions for building a protein. Instead, researchers study such variants to see if they might influence how nearby genes are regulated or expressed. While many intergenic variants have no known impact on health or physical traits, others are identified through genome-wide association studies (GWAS) as markers that correlate with certain biological characteristics.
Research and Associations
The rs3919995 variant is listed in the GWAS Catalog, a comprehensive resource that tracks findings from studies looking for links between genetic variants and various human traits or diseases. When a variant is included in this catalog, it means that at least one study has observed a statistical association between the variant and a specific trait. However, it is important to note that an association does not necessarily mean the variant causes the trait. In the case of rs3919995, the evidence strength is currently categorized as limited. This suggests that while initial research has flagged this location, more robust, large-scale studies are required to confirm the nature of the association and to understand the underlying biological mechanisms, if any, that might be involved.
Population Frequency
Genetic variants like rs3919995 are often distributed differently across various human populations. The frequency of a specific allele—the version of the DNA at that location—can vary significantly depending on an individual's ancestral background. Some variants are common in one geographic region but rare in another. For rs3919995, the population frequency is noted as variable. This means that there is no single, universal frequency for the variant across all global populations. Researchers use large databases like gnomAD to estimate these frequencies, which helps them understand the genetic diversity of human populations. Because the frequency is variable, the likelihood of carrying a specific genotype for this SNP depends heavily on the population group being studied.
Interpreting Genetic Information
When encountering information about variants like rs3919995, it is essential to maintain a clear perspective on what this data means for an individual. Because the evidence for this variant is limited and it is located in an intergenic region, it is not currently used for clinical diagnosis or medical decision-making. Genetic associations identified in research studies are statistical observations made across large groups of people; they do not predict individual health outcomes. If you have questions about your own genetic data or how specific variants might relate to your health, the most appropriate step is to consult with a qualified healthcare provider or a genetic counselor. They can help interpret your results in the context of your personal and family medical history, ensuring that you receive accurate and actionable information.

Frequently asked questions
What does it mean if a variant is intergenic?
An intergenic variant is located in the DNA sequence between genes. Since it is not inside a gene, it does not code for a protein, though it may still play a role in regulating how nearby genes function.
Is rs3919995 associated with a specific disease?
The rs3919995 variant is documented in the GWAS Catalog for associations with certain traits, but the evidence is currently limited. It is not classified as a diagnostic marker for any specific disease.
Can I use this information to change my medical care?
No. This information is for educational purposes only and is not intended for clinical use. Always discuss any concerns about your health or genetic results with a doctor or genetic counselor.
Why is the evidence for this variant considered limited?
Evidence is considered limited when research findings have not yet been replicated across large, diverse populations or when the biological mechanism linking the variant to a trait remains unclear.
