Is Systemic Lupus Erythematosus Genetic?
Systemic lupus erythematosus (SLE or lupus) is a chronic autoimmune disease where the immune system attacks its own tissues. It can affect joints, skin, kidneys, brain, and other organs.
Affects ~1 in 1,000 people.
Genetic Factors Behind Systemic Lupus Erythematosus
Research has identified multiple genetic variants that influence a person's susceptibility to Systemic Lupus Erythematosus. While no single gene determines whether someone will develop this condition, specific variants can increase or decrease risk. Key genes studied in relation to Systemic Lupus Erythematosus include:
STAT4TNIP1BLKIRF5STAT4STAT4 has been associated with systemic lupus erythematosus in genetic studies; as with most common variants, its individual effect is modest and works alongside many other genetic and non-genetic factors.
TNIP1TNIP1 has been associated with systemic lupus erythematosus in genetic studies; as with most common variants, its individual effect is modest and works alongside many other genetic and non-genetic factors.
BLKBLK has been associated with systemic lupus erythematosus in genetic studies; as with most common variants, its individual effect is modest and works alongside many other genetic and non-genetic factors.
IRF5IRF5 has been associated with systemic lupus erythematosus 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 Systemic Lupus Erythematosus. 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 Systemic Lupus Erythematosus Results
After uploading your DNA file, you will receive a detailed health risk report covering 52 conditions, including Systemic Lupus Erythematosus. 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 STAT4, TNIP1, BLK, and IRF5. Risk levels range from "Below Average" to "Significantly Increased," with population percentile comparisons to contextualize your results.
Frequently Asked Questions About Systemic Lupus Erythematosus
Which genes are linked to Systemic Lupus Erythematosus?
Systemic Lupus Erythematosus has been associated with STAT4, TNIP1, BLK, IRF5 in genome-wide association studies. No single variant causes the condition — genetic susceptibility is the sum of many small effects.
If I carry risk variants, will I develop Systemic Lupus Erythematosus?
Carrying risk alleles raises probability, not certainty. Most common conditions arise from genes interacting with lifestyle and environment over decades, so a higher genetic risk score is best used as motivation for the relevant screening and prevention measures, not as a prediction.
What DNA data do I need for this analysis?
Any standard consumer-genetics raw file (23andMe, AncestryDNA, MyHeritage, FamilyTreeDNA, or VCF from sequencing) contains the relevant variants. Analysis runs locally on your device, so your genetic data stays private.
