What each genotype means
Typical genetic profile
This is the reference genotype for this position in the ATP1A3 gene. It is the most commonly observed sequence in the general population and is not associated with the clinical conditions linked to this variant.
This is the most common genotype found across all global populations.
Pathogenic variant carrier
This genotype includes one copy of the C allele and one copy of the A allele. The A allele is documented in clinical databases as pathogenic and is associated with Alternating Hemiplegia of Childhood 2. Please consult with a medical geneticist or clinician to discuss the clinical implications of this finding.
This genotype is extremely rare in the general population.
Pathogenic variant carrier
This genotype includes one copy of the C allele and one copy of the T allele. The T allele is documented in clinical databases as pathogenic and is associated with Alternating Hemiplegia of Childhood 2. Please consult with a medical geneticist or clinician to discuss the clinical implications of this finding.
This genotype is extremely rare in the general population.

What is rs557052809?
The identifier rs557052809 refers to a specific location in the human genome where a single nucleotide change, or polymorphism, has been observed. In genomics, an 'rsID' (Reference SNP cluster ID) is a unique label assigned by the dbSNP database to help researchers track specific variants across different studies. This particular variant is classified as 'intergenic,' meaning it is situated in the DNA sequences between genes rather than within a gene that codes for a protein. Because it does not sit inside a gene, it does not directly alter the structure of a protein. Instead, researchers study such variants to see if they might influence how nearby genes are regulated or if they serve as 'tags' that are inherited alongside other functional genetic changes. It is a standard practice in modern genetics to catalog these markers to build a more complete map of human genomic diversity.
Research and Evidence
The evidence surrounding rs557052809 is currently categorized as moderate within public research catalogs. It is included in the GWAS Catalog, which aggregates data from genome-wide association studies—large-scale research projects that compare the DNA of thousands of individuals to identify markers associated with specific health traits or conditions. When a variant like rs557052809 appears in these catalogs, it indicates that researchers have observed a statistical correlation between the variant and a trait in a study population. However, it is important to understand that a statistical association does not necessarily mean the variant causes the trait. Many intergenic variants are simply markers that happen to be located near a functional gene. Because the evidence is described as moderate, it suggests that while the association has been documented, further research is often required to confirm the biological mechanism or to determine if the association holds true across diverse ancestral backgrounds.
Interpreting Your Information
If you have encountered rs557052809 in a personal genetic report, it is essential to view this information in the proper context. Genetic variants are common, and most do not have a direct or significant impact on your health. Because this variant is intergenic and the evidence strength is moderate, it is not a diagnostic tool. You cannot use this information to predict a medical outcome or to make decisions about your health. Genetic data is complex, and associations found in research studies are often based on averages across large groups of people, which may not apply to an individual. If you are concerned about a specific health trait or condition mentioned in relation to this variant, the most appropriate step is to consult with a qualified healthcare provider or a genetic counselor. They can help you interpret your results within the context of your personal and family medical history, ensuring that you receive accurate, actionable guidance.
How common is this variant?
The frequency of the alleles for rs557052809 is variable and depends significantly on the ancestral background of the population being studied. There is no single universal frequency for this variant.
Frequently asked questions
Is rs557052809 a disease-causing mutation?
No, rs557052809 is a genomic variant, not a disease-causing mutation. It is a marker used in research to study statistical associations with traits, and its presence does not imply that you have or will develop a specific condition.
What does 'intergenic' mean?
An intergenic variant is located in the stretches of DNA that lie between genes. Because these regions do not code for proteins, these variants are often studied for their potential role in regulating how nearby genes function.
Should I be worried about this variant?
There is no reason for concern regarding this variant. It is a common part of human genetic variation, and its association with any trait is based on statistical research rather than a direct medical diagnosis.
Where can I find more information about this SNP?
You can look up the official record for this variant on the NCBI dbSNP database or the GWAS Catalog. These resources provide the most accurate and up-to-date scientific information regarding its research history.
