WFDC11 rs373884229: What Your Genotype Means
The genetic variant rs373884229 is a single nucleotide polymorphism located within the WFDC11 gene. It has been identified in scientific studies as being associated with variations in the measurement of elafin in human blood.
What each genotype means
Typical elafin measurement
This genotype represents the most common genetic state for this variant. Research indicates this variant is associated with variations in elafin levels in the blood, though the specific functional impact of this genotype remains a subject of ongoing study. As this is a trait-associated marker rather than a diagnostic one, it does not indicate a health condition.
This is the most frequent genotype observed in global populations.
Varied elafin measurement
Carrying one copy of the G allele is associated with differences in measured elafin levels in the blood compared to the A/A genotype. Current evidence links this variant to these measurements, but the clinical significance of these variations is not fully established. This finding should be viewed as a trait association rather than a medical diagnosis.
This heterozygous genotype is found at varying frequencies across different ancestral groups, though specific global prevalence data is not currently recorded.
Varied elafin measurement
Carrying two copies of the G allele is associated with differences in measured elafin levels in the blood. While this variant is linked to elafin measurement in scientific literature, the biological implications of these specific levels are not yet clearly defined. This information is for educational purposes and does not constitute a medical diagnosis.
This genotype is less common than the A/A state, with frequency varying significantly by population ancestry.
Understanding rs373884229
A single nucleotide polymorphism, or SNP, is a variation at a single position in a DNA sequence among individuals. The variant rs373884229 is a specific location in the human genome where researchers have observed differences between people. In the context of genomics, identifying these variants helps scientists understand how subtle changes in our genetic code might influence biological traits. This particular SNP is situated within the WFDC11 gene, which provides instructions for producing a specific protein. By studying where this variant sits, researchers can begin to map out how it might interact with the surrounding genetic environment to influence protein expression or function.
The Role of the WFDC11 Gene
The WFDC11 gene encodes a member of the WAP-type four-disulfide core (WFDC) domain family. Proteins in this family are characterized by a specific structural motif containing eight cysteine residues that form four disulfide bonds. This structural arrangement is critical for the protein's function, which typically involves acting as a protease inhibitor. Protease inhibitors are molecules that regulate the activity of enzymes capable of breaking down proteins. By controlling these enzymes, the WFDC11 protein plays a role in maintaining biological balance within tissues. Understanding the function of this gene is essential for interpreting how genetic variations like rs373884229 might potentially influence the levels or activity of proteins like elafin in the body.
Research Associations and Evidence
The association between rs373884229 and elafin measurement in blood has been documented in the GWAS Catalog, a curated collection of genome-wide association studies. It is important to note that the evidence strength for this association is currently classified as moderate. GWAS studies look for statistical correlations between specific genetic variants and measurable traits across large populations. While these findings provide valuable insights into the genetic architecture of human traits, they represent statistical associations rather than direct cause-and-effect relationships. Because the evidence is moderate, further research is required to fully understand the biological mechanisms linking this specific SNP to elafin levels. As with many genetic findings, these results are based on population-level data and may not apply to every individual in the same way.
Interpreting Your Genetic Information
Information about genetic variants like rs373884229 is intended for educational purposes to help the public understand the current state of genomic research. It is crucial to recognize that having a particular genotype does not constitute a medical diagnosis or a prediction of health outcomes. Genetic associations are complex and are often influenced by a combination of other genes, environmental factors, and lifestyle choices. If you have questions about your health or specific biomarkers like elafin, it is best to consult with a qualified healthcare professional. They can provide context based on your personal medical history and clinical testing, which are far more informative than a single genetic variant. Always rely on clinical guidance rather than raw genetic data when making decisions about your health.

There is currently no specific population frequency data recorded for the rs373884229 variant in major public databases.
Frequently asked questions
What is the WFDC11 gene?
The WFDC11 gene encodes a protein that belongs to the WAP-type four-disulfide core domain family. These proteins generally function as protease inhibitors, which help regulate enzyme activity in the body.
What does it mean if a variant is associated with a trait?
An association means that researchers have found a statistical link between a specific genetic variant and a trait in a population. It does not necessarily mean the variant causes the trait directly.
Should I be concerned about my rs373884229 genotype?
No, this variant is a common genetic difference and is not a medical diagnosis. You should discuss any health concerns with your doctor, who can interpret your results in the context of your overall health.
Where can I find more information on this SNP?
You can search for the rsID 'rs373884229' in the GWAS Catalog or the NCBI dbSNP database. These resources provide the most up-to-date scientific information regarding known genetic variants.
