WWOX rs1074963: Understanding This Genetic Variant
The rs1074963 variant is a single nucleotide polymorphism located within the WWOX gene, a region known for its role as a tumor suppressor. Research has investigated this specific variant for potential associations with the risk and clinical outcomes of osteosarcoma, a type of bone cancer.
What each genotype means
Baseline WWOX variant profile
This genotype represents the homozygous state for the reference allele at this position in the WWOX gene. Research into this specific variant has explored its potential association with osteosarcoma risk and clinical outcomes, though current evidence is limited and primarily derived from specific population studies. This finding does not constitute a diagnosis or a prediction of disease.
The frequency of this genotype varies by ancestry and is not widely established in global population databases.
Heterozygous WWOX variant profile
This genotype indicates you carry one copy of the reference allele and one copy of the alternative allele at this position. Studies have investigated whether variations in the WWOX gene influence susceptibility to certain cancers, such as osteosarcoma, but the clinical significance remains a subject of ongoing research. This result should be interpreted as a statistical observation rather than a medical diagnosis.
The frequency of this genotype varies by ancestry and is not widely established in global population databases.
Alternative WWOX variant profile
This genotype represents the homozygous state for the alternative allele at this position. While this variant has been studied in the context of osteosarcoma risk and clinical progression, the evidence is not sufficient to determine a definitive health impact for an individual. Please consult with a healthcare professional if you have concerns regarding your personal or family health history.

What is rs1074963?
The variant rs1074963 is a single nucleotide polymorphism (SNP) found on chromosome 16 within the WWOX gene. In genetics, a SNP represents a variation at a single position in the DNA sequence among individuals. This specific variant is located in a region of the genome that has been extensively studied due to its proximity to the FRA16D chromosomal fragile site. Fragile sites are specific areas of chromosomes that are prone to breakage or gaps when cells are under replication stress. Because rs1074963 sits within the WWOX gene, researchers have focused on whether this variation might influence the gene's stability or function, particularly in the context of how cells manage growth and division.
The Role of the WWOX Gene
The WWOX gene, which stands for WW domain-containing oxidoreductase, is a well-characterized tumor suppressor gene. Tumor suppressors are essential components of the body's cellular machinery that help regulate cell growth and prevent the development of cancer. When the WWOX gene functions normally, it helps control cell cycles and can trigger apoptosis, or programmed cell death, in cells that are damaged or behaving abnormally. Because it is located at a fragile site, the WWOX gene is susceptible to deletions and mutations. Beyond its role in cancer, WWOX is also highly expressed in the brain and spinal cord, and severe mutations in this gene have been linked to rare, autosomal recessive neurological conditions, including developmental delay and epilepsy.
Research and Evidence
Scientific interest in rs1074963 has primarily centered on its potential link to osteosarcoma, a primary bone malignancy that most commonly affects children and adolescents. Some studies have explored whether specific genotypes of this variant correlate with an increased risk of developing the disease or influence clinical outcomes for patients. While these findings have provided interesting insights into the genetic landscape of bone tumors, the evidence remains moderate. It is important to note that genetic associations are often complex and can be influenced by a person's overall genetic background and environmental factors. Current research does not suggest that this variant is a definitive cause of cancer, but rather that it is a marker that may contribute to a broader understanding of susceptibility in certain populations.
Population Frequency
Information regarding the specific population frequency of the rs1074963 variant is not widely documented in standard public databases. Genetic variants often show significant differences in frequency across various ancestral groups, and without large-scale, multi-ethnic data, it is difficult to determine how common this specific SNP is globally. Many studies focusing on this variant have been conducted in specific cohorts, such as young populations in China, which may not reflect the frequency of the variant in other global populations. As more genomic data is collected and shared through projects like gnomAD, our understanding of how common this variant is across different ancestries will likely improve.
What This Information Means for You
If you have encountered this variant in a genetic report, it is important to view the information in the correct context. Genetic variants are common, and most do not have a significant impact on your health. The association between rs1074963 and osteosarcoma is a subject of ongoing scientific research rather than a clinical diagnostic tool. You cannot use this information to predict your personal health outcomes or to make medical decisions. If you have concerns about your family history of cancer or other health conditions, 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 overall health and provide guidance based on established clinical standards.

There is no widely recorded population frequency data for this specific variant in major global databases.
Frequently asked questions
Is rs1074963 a cause of cancer?
No, rs1074963 is not considered a direct cause of cancer. It is a genetic variant that has been studied for its potential association with susceptibility to certain types of bone tumors, but having this variant does not mean an individual will develop cancer.
Should I be worried if I have this variant?
Genetic variants are a normal part of human diversity, and most have no impact on health. Because the evidence linking this variant to health outcomes is moderate and based on specific research studies, it is not a cause for alarm.
Can I use this information to diagnose a condition?
No, this information cannot be used for diagnosis. Genetic testing for health risks should always be performed and interpreted by medical professionals who can consider your full clinical history.
Where can I learn more about the WWOX gene?
You can find reliable information about the WWOX gene and its functions through resources like MedlinePlus Genetics or the NCBI Gene database. These platforms provide comprehensive, peer-reviewed summaries of human genes.
