Is Atrial Fibrillation Genetic?
Atrial fibrillation (AFib) is an irregular and often rapid heart rhythm that can lead to blood clots, stroke, and heart failure. It is the most common type of cardiac arrhythmia.
Affects ~1 in 25 adults over 65.
Genetic Factors Behind Atrial Fibrillation
Research has identified multiple genetic variants that influence a person's susceptibility to Atrial Fibrillation. While no single gene determines whether someone will develop this condition, specific variants can increase or decrease risk. Key genes studied in relation to Atrial Fibrillation include:
PITX24q25KCNN3ZFHX3Each of these genes plays a distinct role in the biological pathways related to Atrial Fibrillation. Variants in these genes have been identified through large-scale genome-wide association studies (GWAS) and replicated across multiple populations.
How GenomeInsight Analyzes Your Risk
GenomeInsight examines your raw DNA data from services like 23andMe, AncestryDNA, or whole-genome sequencing (VCF files) to identify genetic variants associated with Atrial Fibrillation. The analysis is performed entirely in your browser, meaning your genetic data never leaves your device.
For each relevant variant, GenomeInsight reports your genotype, the associated risk allele, the odds ratio from published research, and your overall risk profile compared to the general population. Results are presented with easy-to-understand risk visualizations and percentile rankings.
Genetic risk is only one piece of the puzzle. Lifestyle, diet, environment, and family history all contribute to overall risk. GenomeInsight's analysis is for informational and educational purposes and is not a medical diagnosis.
Understanding Your Atrial Fibrillation Results
After uploading your DNA file, you will receive a detailed health risk report covering 52 conditions, including Atrial Fibrillation. For each condition, GenomeInsight analyzes multiple SNPs (single nucleotide polymorphisms) and calculates a combined risk assessment.
Your results will show whether you carry risk-increasing or protective alleles in genes like PITX2, 4q25, KCNN3, and ZFHX3. Risk levels range from "Below Average" to "Significantly Increased," with population percentile comparisons to contextualize your results.

Coronary Artery Disease
Coronary artery disease (CAD) occurs when plaque builds up in the arteries that supply blood to the heart. It is the leading cause of heart attacks and the most common type of heart disease worldwide.
Hypertension
Hypertension, or high blood pressure, is a chronic condition where blood pressure in the arteries is persistently elevated. It significantly raises the risk of heart disease, stroke, and kidney damage.
Venous Thromboembolism
Venous thromboembolism (VTE) includes deep vein thrombosis and pulmonary embolism. It occurs when blood clots form in veins, often in the legs, and can become life-threatening if a clot travels to the lungs.
Ischemic Stroke
Ischemic stroke occurs when a blood clot blocks or narrows an artery leading to the brain. It accounts for roughly 87% of all strokes and can cause lasting brain damage or death.
