18-4-52A Mold Susceptibility

The 18-4-52A haplotype is linked to a genetic susceptibility to mold-related biotoxins. This means your immune system may not recognize or eliminate mold toxins as effectively as others, which could contribute to symptoms or chronic illness if mold exposure occurs.

What This Doesn’t Mean:
Having this haplotype does not mean you have mold illness, nor does it confirm current or past exposure. It’s simply a clue that your body may be less equipped to detox mold toxins without extra support.









** Your HLA genes are part of your immune system’s ability to recognize and respond to threats. But certain haplotypes are essentially “faulty”—they don’t help your body recognize or clear biotoxins the way most people’s do. This sets off the innate immune response, which triggers inflammation, but the adaptive immune system never kicks in to finish the job. The result? Toxins get trapped in the body, inflammation floods your system, and the immune response never shuts off. This is what can lead to CIRS—Chronic Inflammatory Response Syndrome. *This information is for educational purposes only and not a substitute for medical care. **
