Is Ischemic Stroke Genetic?
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.
Affects ~1 in 6 people in their lifetime.
Genetic Factors Behind Ischemic Stroke
Research has identified multiple genetic variants that influence a person's susceptibility to Ischemic Stroke. While no single gene determines whether someone will develop this condition, specific variants can increase or decrease risk. Key genes studied in relation to Ischemic Stroke include:
HDAC9NINJ2PITX2ABOHDAC9HDAC9 has been associated with ischemic stroke in genetic studies; as with most common variants, its individual effect is modest and works alongside many other genetic and non-genetic factors.
NINJ2NINJ2 has been associated with ischemic stroke in genetic studies; as with most common variants, its individual effect is modest and works alongside many other genetic and non-genetic factors.
PITX2PITX2 has been associated with ischemic stroke in genetic studies; as with most common variants, its individual effect is modest and works alongside many other genetic and non-genetic factors.
ABOABO has been associated with ischemic stroke in genetic studies; as with most common variants, its individual effect is modest and works alongside many other genetic and non-genetic factors.
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 Ischemic Stroke. 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 Ischemic Stroke Results
After uploading your DNA file, you will receive a detailed health risk report covering 52 conditions, including Ischemic Stroke. 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 HDAC9, NINJ2, PITX2, and ABO. Risk levels range from "Below Average" to "Significantly Increased," with population percentile comparisons to contextualize your results.
Frequently Asked Questions About Ischemic Stroke
Which genes are linked to Ischemic Stroke?
The variants most consistently associated with Ischemic Stroke lie in or near HDAC9, NINJ2, PITX2, ABO. Each variant shifts risk modestly on its own; the report combines all of them into an overall genetic risk estimate compared with the reference population.
If I carry risk variants, will I develop Ischemic Stroke?
Not necessarily. A genetic predisposition means your probability is higher than average — it is not a diagnosis. Lifestyle, environment, age and chance all contribute, and most people with elevated genetic risk never develop the condition. Conversely, low genetic risk is not a guarantee of protection.
What DNA data do I need for this analysis?
A raw-data file from 23andMe, AncestryDNA, MyHeritage or a whole-genome VCF covers the markers used in this analysis. Upload takes place entirely in your browser — your file is never transmitted to or stored on any server.

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.
Atrial Fibrillation
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.
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.
