Can Anxiety Be Genetic? – Genes That May Influence Mood and Stress Response

We look at over 900,000 SNP’s and use the latest AI powered software to analyse over 80 million variants that significantly influence your health.

If you’ve ever wondered why you feel anxious without a clear cause, you’re not alone. For many people, anxiety isn’t tied to major life events – it may relate to how their brain and body are wired to process stress. One possible contributor is your genetics.

At Life X DNA™, we provide science-led reports that explore how specific gene variants may influence stress reactivity, neurotransmitter balance and emotional regulation. Our at-home DNA kits are available throughout Australia and New Zealand.

How Your Genes May Affect Anxiety

Genes don’t cause anxiety directly, but they can affect the systems that regulate mood and stress recovery.

Some of the genes with research links to anxiety sensitivity include:

  • COMT – regulates breakdown of dopamine and adrenaline
  • MAOA – affects levels of serotonin and norepinephrine
  • BDNF – involved in brain plasticity and resilience
  • GAD1 – supports GABA signalling, which helps calm the nervous system

Variants in these genes may influence how quickly your brain clears stress hormones or how efficiently it responds to stimulation. This might explain why some people feel anxious or overstimulated even in low-stress environments.

Genetic Testing for Stress Sensitivity and Mood

Life X DNA testing is not a diagnostic tool for anxiety disorders. Instead, it provides personalised, evidence-informed insight into the biological pathways that may influence traits such as:

  • Heightened sensitivity to noise, pressure or caffeine
  • Difficulty winding down after stress
  • Strong physical responses to minor triggers
  • Emotional fluctuations during hormonal or lifestyle shifts

These insights can be particularly helpful if you’ve tried generic stress-management strategies without much effect.

What’s Included in Your Report

Your anxiety-related profile is explored across multiple report sections, including:

  • Neurotransmitter production and receptor function
  • Methylation efficiency and nutrient cofactor status
  • Cortisol and stress hormone response pathways
  • Inflammation and oxidative stress sensitivity

Life X DNA reports are delivered via a secure online portal and include over 1200 pages of personalised, interactive content.

Trusted Across Australia and New Zealand

Our test kits are processed in an ISO-certified lab in Perth and available for delivery across both Australia and New Zealand. Your data is never shared or sold, and our reporting is always private, secure, and educational in intent.

FAQs – Genetics and Anxiety

Yes. Some genes influence how your body handles stress and mood signalling. These don’t determine whether you will experience anxiety, but they may affect your baseline sensitivity or resilience.

No. Life X DNA reports are informational and not intended to replace medical advice or clinical assessment.

We analyse COMT, MAOA, BDNF, GAD1, MTHFR and others involved in neurotransmitter metabolism, methylation and stress regulation.
