NLRP3 and Chronic Inflammation: What Your Genotype Means for Healthy Aging

Inflammation is the body’s natural response to injury and infection. When it becomes chronic, however, it can damage healthy tissue and contribute to conditions such as heart disease, type 2 diabetes, arthritis, and other inflammatory disorders. The NLRP3 gene plays a central role in this process by producing a protein complex called the NLRP3 inflammasome. This complex senses cellular stress and danger signals and triggers release of inflammatory molecules like interleukin-1β, which amplify immune responses.

Variations in NLRP3 can change how easily or persistently the inflammasome activates. Knowing your genotype for the rs35829419 variant can help you understand whether your inflammatory response might be more likely to run hot and, if so, which lifestyle and wellness habits can help reduce long-term risk. The information below is educational and not medical advice. PlexusDx does not provide medical advice. Always discuss genetic results and health decisions with your healthcare provider.

How NLRP3 Affects Health

  • Normal NLRP3 activation helps clear infections and heal tissue.
  • Overactive or persistent NLRP3 activation can promote chronic inflammation that harms tissues and organs.
  • Chronic inflammation contributes to cardiovascular disease, metabolic dysfunction, certain autoimmune and autoinflammatory conditions, and age-related functional decline.
  • Genetic variation at rs35829419 influences how readily the NLRP3 inflammasome activates; lifestyle and environment also strongly affect inflammation.

Practical Steps to Support Balanced Inflammation

Regardless of genotype, the following strategies help reduce chronic inflammation and support healthy aging. If your genotype indicates higher risk, these steps are especially important. Discuss any major changes with your healthcare provider.

  • Diet: Emphasize whole, minimally processed foods. Focus on fruits, vegetables, high-fiber whole grains, legumes, nuts, seeds, and lean protein. Prioritize sources of omega-3 fatty acids such as fatty fish, walnuts, and flaxseed. Limit refined carbs, added sugars, processed meats, and trans fats.
  • Healthy fats: Include sources of monounsaturated and omega-3 fats. Replace some saturated fats with olive oil, avocado, fatty fish, and nuts.
  • Regular exercise: Aim for a mix of aerobic activity and resistance training. Physical activity reduces inflammatory markers, supports metabolic health, and helps maintain healthy weight.
  • Weight management: Excess body fat, especially around the abdomen, promotes inflammation. Modest weight loss can reduce inflammatory markers and improve metabolic risk.
  • Sleep: Prioritize regular, restorative sleep. Poor sleep increases inflammatory signaling.
  • Stress management: Chronic psychological stress raises inflammation. Practices such as mindfulness, yoga, deep breathing, and cognitive behavioral approaches can help.
  • Avoid tobacco and limit alcohol: Smoking and excessive alcohol intake elevate inflammation and disease risk.
  • Regular checkups and blood tests: Work with your provider to monitor key biomarkers such as fasting glucose, lipid panel, C-reactive protein (CRP), HbA1c, and vitamin D status when appropriate.
  • Targeted supplements: After discussing with your provider, consider omega-3 supplements, vitamin D if deficient, and curcumin as they may help modulate inflammation. Avoid self-prescribing high doses without medical supervision.

Genetic Interpretation — rs35829419 (NLRP3)

2 effect alleles (AA)

If your genotype is AA, you carry two copies of the effect allele for rs35829419. This genotype is associated with a higher tendency for the NLRP3 inflammasome to activate more easily or persistently. That may lead to longer or stronger inflammatory responses in the body. While this does not guarantee that you will develop a chronic inflammatory disease, it suggests a greater susceptibility to conditions where inflammation plays a key role, including certain cardiovascular and metabolic disorders and autoinflammatory conditions.

What you can do:

  • Be proactive with an anti-inflammatory diet rich in whole plant foods and omega-3s.
  • Prioritize regular physical activity and resistance training to lower systemic inflammation.
  • Monitor inflammatory biomarkers with your clinician, such as high-sensitivity C-reactive protein when indicated.
  • Work to achieve and maintain a healthy weight and body composition.
  • Address sleep, stress, and lifestyle factors that can amplify inflammation.
  • Talk with your healthcare provider about supplements like omega-3s, curcumin, and testing vitamin D, rather than starting supplements on your own.
1 effect allele (AC)

If your genotype is AC, you carry one copy of the effect allele for rs35829419. This suggests a modest increase in the tendency for NLRP3 inflammasome activation compared to the typical genotype. You may be somewhat more prone to stronger or longer-lasting inflammatory responses under stress or with other risk factors present. This does not mean you will develop disease, but it indicates that lifestyle and environmental factors are important to manage.

What you can do:

  • Follow an anti-inflammatory eating pattern with plenty of vegetables, fruits, whole grains, legumes, and omega-3 sources.
  • Maintain regular exercise habits and avoid prolonged sedentary behavior.
  • Manage stress and prioritize regular, high-quality sleep.
  • Consider periodic monitoring of inflammation-related biomarkers if you have other risk factors, such as obesity, hypertension, or a family history of inflammatory disease.
  • Discuss supplements and targeted interventions with your healthcare provider if you have symptoms or elevated biomarkers.
0 effect alleles (CC)

If your genotype is CC, you carry two copies of the non-effect allele at rs35829419, which is the typical genotype. This suggests your NLRP3 inflammasome functions in the standard way without extra genetic drive toward increased activation. However, chronic inflammation can still arise from lifestyle, environmental exposures, infections, or other medical conditions.

What you can do:

  • Continue or adopt anti-inflammatory lifestyle habits: balanced diet, exercise, healthy weight, sleep, and stress management.
  • Avoid tobacco and limit alcohol consumption.
  • Monitor general health through routine clinical care and blood testing as advised by your healthcare provider.
  • If you develop symptoms of chronic inflammation or have other risk factors, consult your provider about further evaluation and personalized strategies.

Blood Tests and Monitoring Considerations

  • High-sensitivity C-reactive protein (hs-CRP): a general marker of systemic inflammation.
  • Fasting glucose and HbA1c: track metabolic health and risk for diabetes.
  • Lipid panel: cardiovascular risk assessment.
  • Vitamin D: low levels can contribute to immune dysregulation; correct deficiency under medical guidance.
  • Other autoimmune or inflammatory panels only as clinically indicated by symptoms and provider judgment.

Final Notes and Disclaimer

This report is intended to help you understand how variation in the NLRP3 gene at rs35829419 may relate to inflammation and long-term health. Genetic results are one piece of the puzzle. Environment, lifestyle, other genes, and medical history all shape your overall risk. PlexusDx does not provide medical advice. Always discuss these results, any symptoms, and any changes to diet, supplements, or treatment with your healthcare provider before making decisions. Together you can build a plan tailored to your genetics, health goals, and medical needs.
