CGGBP1 rs114017876: What Your Genotype Means
The rs114017876 variant is a single nucleotide polymorphism located near the CGGBP1 gene on chromosome 3. Research has identified this variant as part of a cluster of genetic markers associated with differences in perceived facial aging progression.
What each genotype means
Higher facial aging progression
Research indicates that the A allele is associated with lower expression of the CGGBP1 gene, which may correlate with a higher perceived facial aging progression (PFAP). Because CGGBP1 is thought to play a role in telomere protection and DNA maintenance, this genotype may reflect a biological predisposition toward faster skin aging markers. This association is based on statistical population studies and does not predict individual outcomes.
The frequency of this genotype varies by ancestry and is currently under investigation in broader population studies.
Intermediate facial aging profile
Carrying one copy of the A allele and one copy of the G allele results in an intermediate genetic profile regarding the expression of the CGGBP1 gene. While the A allele is linked to lower gene expression and higher perceived facial aging progression, the presence of the G allele may modulate this effect. These findings are based on statistical associations and should not be used to diagnose or predict personal skin aging trajectories.
The frequency of this genotype varies by ancestry and is currently under investigation in broader population studies.
Lower facial aging progression
The G allele is associated with higher expression of the CGGBP1 gene compared to the A allele. Higher expression of this gene is hypothesized to support telomere protection and potentially slow down the progression of perceived facial aging. This interpretation is based on statistical associations observed in research and does not guarantee specific skin aging outcomes.

Understanding the Variant and Its Location
The rs114017876 variant is a specific change in the DNA sequence located on chromosome 3. It sits in a region near the CGGBP1 and ZNF654 genes. In genomics, a single nucleotide polymorphism (SNP) like rs114017876 represents a variation at a single position in the DNA building blocks. This particular SNP is often studied alongside other nearby variants because they are frequently inherited together in a block, a phenomenon known as linkage disequilibrium. By analyzing these clusters, researchers can identify genomic regions that may contribute to complex physical traits. Because this variant is located in a non-coding region near genes involved in cellular maintenance, scientists investigate whether it influences how nearby genes are turned on or off, rather than changing the structure of a protein directly.
The Role of the CGGBP1 Gene
The CGGBP1 gene encodes a protein that binds to specific DNA sequences, particularly those rich in CGG repeats. This protein is essential for maintaining genomic integrity, regulating gene expression, and managing the epigenome—the chemical markers that control how genes function. Research indicates that CGGBP1 helps protect telomeres, the protective caps at the ends of chromosomes that shorten as cells age. By restricting cytosine methylation at specific promoter regions, CGGBP1 ensures that transcription factor binding sites remain accessible, which is vital for normal cellular function. Because of its involvement in DNA damage repair and telomere metabolism, CGGBP1 is a subject of interest in studies exploring the biological mechanisms of cellular senescence and aging processes.
Research on Facial Aging Associations
Recent genome-wide association studies (GWAS) have identified rs114017876 as one of several variants associated with perceived facial aging progression. In these studies, researchers assessed facial aging in cohorts over time to determine if specific genetic markers correlated with how quickly individuals appeared to age. The evidence for this association is considered moderate, as it is part of a broader signal involving multiple SNPs in the same chromosomal region. Specifically, the A allele of rs114017876 has been linked to higher perceived facial aging scores and lower expression levels of the CGGBP1 gene in certain tissues, such as the arterial aorta. While these findings provide a potential biological link between gene expression and physical appearance, the research is ongoing, and the effect of this single variant is likely influenced by a combination of other genetic factors and environmental exposures, such as sun exposure.
Interpreting Your Genetic Information
It is important to understand that genetic associations with complex traits like facial aging are statistical in nature and do not provide a definitive prediction of your personal aging process. Many factors, including lifestyle, nutrition, and environmental history, play a significant role in how skin and facial features change over time. You cannot use this information to diagnose a medical condition or predict specific health outcomes. If you are interested in skin health or aging, the most effective approach is to consult with a dermatologist or healthcare provider who can offer evidence-based guidance on skincare and sun protection. Genetic data should be viewed as one small piece of a much larger puzzle, and it is not a substitute for professional medical advice or a comprehensive health assessment.
How common is this variant?
The frequency of the rs114017876 variant is variable across different ancestral populations. Specific frequency data for this SNP can be found in large-scale genomic databases like gnomAD, which aggregate data from diverse global cohorts.
Frequently asked questions
Is rs114017876 a cause of skin aging?
No, this variant is not a direct cause of skin aging. It is a statistical marker associated with perceived facial aging progression in research studies, meaning it is linked to the trait but does not determine it on its own.
Can I use this SNP to predict how I will age?
No. Facial aging is a complex trait influenced by many genes, environmental factors, and lifestyle choices. A single SNP cannot provide a reliable prediction of your personal aging trajectory.
What should I do if I have the A allele?
The presence of a specific allele does not require medical action. If you have concerns about skin health or aging, consult a dermatologist for personalized advice on skincare and sun protection.
Where can I find more information on CGGBP1?
You can search for the CGGBP1 gene on resources like MedlinePlus Genetics or the NCBI Gene database. These sites provide detailed information on the gene's biological functions and its role in cellular processes.
