What is mood?
Mood is the background emotional tone that colors your day. It is shaped by chemical messengers in the brain such as serotonin and dopamine, by your stress hormone system, and by how flexible your brain is in adapting to experience. Sleep, movement, light exposure, nutrition and relationships all feed into it. Mood naturally rises and falls, and that variation is a normal part of being human.
How your genes play a role
Genes influence how your brain makes, moves and recycles its chemical messengers, and how your body responds to stress. Some variants affect serotonin transport, others the way stress hormones are switched on and off. These differences may make some people more sensitive to their surroundings, for better and for worse. They describe tendencies, never a fixed emotional destiny.
Understanding your mood biology can bring a sense of self compassion. If you learn that your stress response may run a little longer, or that you may be more sensitive to your environment, small choices start to make more sense. You can notice what steadies you, protect your sleep and build supportive routines. It can also enrich conversations with a clinician or therapist about what works for you.
What your report shows
Your Mood results are explained in plain language in your private EvoDNA account, alongside the other areas in your kit.
- Serotonin handlingHow your genes may influence the recycling of serotonin between brain cells.
- Stress responseHow readily your stress hormone system may switch on and settle back down.
- Brain adaptabilityVariants linked to how your brain grows new connections in response to experience.
- Sensitivity to settingWhether you may be more responsive to the environment around you.
| Gene | What it does | Result |
|---|---|---|
| SERT | The serotonin transporter, which clears serotonin from the space… | Typical |
| COMT | Breaks down dopamine in the front of the brain,… | Moderate effect |
| BDNF | Makes a growth factor that helps brain cells form… | Typical |
Each result comes with a plain-language explanation and practical points to discuss with your clinician.

Genes we analyze
| Gene | Role |
|---|---|
| SERT | The serotonin transporter, which clears serotonin from the space between nerve cells so it can be reused. |
| COMT | Breaks down dopamine in the front of the brain, which may influence focus and emotional balance. |
| BDNF | Makes a growth factor that helps brain cells form and strengthen connections. |
| FKBP5 | Helps regulate how the body responds to the stress hormone cortisol and how quickly that response settles. |
| CRHR1 | Codes for the receptor that receives the signal starting the body's stress hormone cascade. |
Full panel: 12 genes
SERT, COMT, BDNF, FKBP5, CRH, CRHR1, CACNA1C, NCAN, ITIH3, MIR137, PCDH11Y, ROBO1
Putting results to use
Many people use their results as a starting point for conversations with their clinician about:
Spending time outdoors early in the day is often discussed as a support for mood and sleep.
Regular activity you enjoy, even a daily walk, is widely linked with a brighter mood.
Time with people who feel safe and supportive can help buffer everyday stress.
Protecting your sleep may help keep emotional reactions steadier through the day.
Questions
Can my DNA explain how I feel?
Only partly. Your genes may shape your tendencies, but your mood is also influenced by sleep, life events, relationships and many other factors that change over time.
Does this test diagnose depression or anxiety?
No. This report is educational and does not diagnose any condition. If you are concerned about your mood, please speak with a qualified health professional.
Can I change my mood biology?
Your genes stay the same, but how they are expressed can respond to your habits and environment. Sleep, movement and supportive relationships are often part of that conversation.
