What is mold sensitivity?
Molds are fungi that thrive in damp places, from bathrooms and basements to leaf piles. They release tiny spores and, in some cases, other compounds into the air. When you breathe these in, your immune system decides whether to ignore them or respond. Most people clear them without noticing. Some people, however, experience more noticeable reactions, such as congestion, fatigue or airway irritation, especially after prolonged exposure in damp buildings.
How your genes play a role
Your genes help shape that response. Certain HLA types, such as variants of HLA-DRB1, HLA-DQB1 and HLA-DQA1, influence how immune cells recognize fungal fragments, and are a focus of research on environmental sensitivity. TLR3 and TLR4 are sensors that help detect microbial patterns. Cytokine genes like IL6, IL1B, TNF and IL10 help determine how strong and how lasting a response may be.
Your home, office and car are environments you spend many hours in. Understanding how your body may respond to common environmental exposures can help you make thoughtful choices about ventilation, humidity and the spaces you spend time in. It can also offer useful context if you notice that you feel different in certain buildings, and give you and your clinician a more personal starting point.
What your report shows
Your Mold Sensitivity results are explained in plain language in your private EvoDNA account, alongside the other areas in your kit.
- Recognition profileHLA variants that may influence how your immune system recognizes fungal material.
- Environmental sensorsVariants in receptors that help detect microbial patterns in the air you breathe.
- Response strengthCytokine gene patterns linked to how strongly your body may react.
- ResolutionGenes that may influence how easily your body settles after an exposure.
| Gene | What it does | Result |
|---|---|---|

Each result comes with a plain-language explanation and practical points to discuss with your clinician.

Genes we analyze
| Gene | Role |
|---|---|
| HLA-DRB1 | Helps immune cells present fragments of outside material, including fungal proteins, to helper T cells. |
| TLR4 | Encodes a sensor that detects microbial molecules and helps start the body's early defense. |
| IL1B | Produces a messenger that helps trigger inflammation and fever-type responses. |
| IL10 | Produces a calming messenger that helps immune responses wind down. |
| IL8 | Produces a signal that calls white blood cells called neutrophils to areas of irritation. |

Putting results to use
Many people use their results as a starting point for conversations with their clinician about:
Keeping indoor humidity moderate and fixing leaks quickly are common ways to limit mold growth.
Good ventilation, especially in kitchens and bathrooms, helps keep spaces dry.
Paying attention to how you feel in different buildings can reveal helpful patterns.
A clinician can help you explore environmental concerns and decide whether testing is useful.
Questions
Does this mean I am allergic to mold?
Not necessarily. Your report shows genetic tendencies in how your immune system may respond to environmental exposures. Allergy and other clinical testing are needed to confirm specific sensitivities.
Should I have my home tested for mold?
Genetics alone is not a reason to test your home. If you see visible mold, smell mustiness or have water damage, addressing it is sensible for everyone.
Why are HLA genes included here?
HLA genes influence how immune cells recognize outside material. Researchers study certain HLA types in relation to how people respond to environmental exposures.
