AURKAIP1 rs9554: Understanding This Genetic Variant
The rs9554 variant is a genetic change located within the AURKAIP1 gene. This gene plays a critical role in regulating mitochondrial function and the stability of Aurora-A kinase, a protein essential for cell division.
What each genotype means
Typical AURKAIP1 sequence
This is the most common genotype observed in human populations. The AURKAIP1 gene plays a dual role in regulating the activity of Aurora-A kinase and supporting mitochondrial protein synthesis. As a carrier of this genotype, your genetic sequence at this position aligns with the reference sequence widely used in research studies.
This is the predominant genotype found in the vast majority of individuals across all major global ancestries.
Typical AURKAIP1 sequence with variation
This genotype indicates you carry one copy of the reference allele and one copy of the less common G allele at this location. Research into the AURKAIP1 gene primarily focuses on its role in mitochondrial function and its interaction with kinases; currently, there is no significant evidence suggesting that this specific variation results in clinically actionable changes to these biological processes.
This genotype is very rare, reflecting the low overall frequency of the G allele in most populations.
Typical AURKAIP1 sequence with variation
This genotype indicates you carry two copies of the less common G allele at this location. While AURKAIP1 is known to be involved in critical cellular pathways such as mitosis and mitochondrial translation, current scientific literature does not classify this specific variant as a known cause of, or strong risk factor for, any specific health condition.
This genotype is extremely rare, occurring in a very small fraction of the global population.
What is rs9554 and Where is it Located?
The variant rs9554 is a single nucleotide polymorphism (SNP) situated within the AURKAIP1 gene. In human genetics, SNPs represent the most common type of genetic variation, occurring when a single building block of DNA—a nucleotide—is replaced by another. The AURKAIP1 gene is located on the short arm of chromosome 1 (1p36.33). This specific region of the genome is involved in various cellular processes, and variants here are studied for their potential influence on how the body maintains cellular health and regulates protein stability. Because rs9554 is located within a protein-coding gene, researchers investigate whether such variants might alter the structure or expression levels of the resulting protein, potentially impacting downstream biological pathways.
The Role of the AURKAIP1 Gene
The AURKAIP1 gene encodes the Aurora kinase A-interacting protein 1. This protein is primarily recognized for its role in the mitochondria, where it contributes to mitochondrial ribosomal function and translation. Beyond its mitochondrial duties, AURKAIP1 acts as a regulator of Aurora-A kinase. Aurora-A kinase is a vital enzyme that ensures cells divide correctly; if its levels are not tightly controlled, it can lead to errors in cell cycle progression. AURKAIP1 helps manage these levels by facilitating the degradation of Aurora-A kinase when it is no longer needed. By acting as a bridge between mitochondrial health and the cell cycle, AURKAIP1 is considered an essential protein for maintaining core cellular functions rather than being restricted to a single tissue type.
Research Associations and Evidence Strength
Current scientific literature regarding rs9554 indicates that the evidence linking this specific variant to clinical traits is moderate. While the AURKAIP1 gene itself is well-characterized in molecular biology for its role in protein degradation and mitochondrial pathways, specific GWAS (Genome-Wide Association Study) data for rs9554 does not currently establish it as a primary driver for common complex diseases. Research often focuses on the gene's broader involvement in cancer biology, particularly how its expression levels might influence tumor progression by stabilizing other proteins like DDX5. Because the evidence for rs9554 is not definitive, it is important to view any associations with caution. Genetic variants often work in concert with environmental factors and other genes, meaning a single SNP rarely dictates a specific health outcome on its own.
Population Frequency
The rs9554 variant is considered rare in the general population, with a reported frequency of approximately 0.0000544. This low frequency suggests that the variant is not widely distributed across global ancestries. Because it is uncommon, large-scale studies are required to fully understand its distribution and potential impact across different ethnic groups. When a variant is this rare, it is often difficult to gather enough statistical power to confirm its association with specific traits or conditions, which is why the current evidence remains limited. Researchers continue to monitor such variants in large genomic databases to see if new data emerges as more diverse populations are sequenced.
What You Can and Cannot Do With This Information
Understanding your genetic profile can be an educational experience, but it is important to maintain realistic expectations regarding what this information means for your health. You cannot use the presence of the rs9554 variant to diagnose a medical condition or predict a specific health outcome. Genetic associations are statistical in nature and do not imply direct causation. If you have concerns about your health or are interested in how your genetics might influence your well-being, the best course of action 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. Never make changes to your lifestyle or medical care based solely on a single genetic variant report.

Frequently asked questions
Is rs9554 associated with a specific disease?
Currently, there is no definitive evidence linking rs9554 to a specific disease. While the AURKAIP1 gene is involved in important cellular processes, this specific variant is not widely recognized as a primary cause of any clinical condition.
Should I be worried if I have the minor allele for rs9554?
No, there is no reason for concern. Genetic variants are a normal part of human diversity, and most do not have a significant impact on your health. Always consult a doctor if you have specific health concerns.
How do I find out if I have this variant?
This variant is typically identified through whole-genome or whole-exome sequencing. If you have received a report from a genetic testing service, you can check your raw data for the rsID rs9554.
Does this variant affect how I metabolize medication?
There is no current evidence in the Pharmacogenomics Knowledge Base (PharmGKB) or CPIC guidelines suggesting that rs9554 affects medication response. Always discuss your medications and any genetic concerns with your pharmacist or physician.
