New Study: Common PFAS Chemicals Alter Gene Activity, Linked to Multiple Diseases

PFAS Chemicals Found to Change Genes -Implications for Disease and Treatment

A new study has revealed that exposure to common PFAS “forever chemicals” can cause changes in gene activity, helping explain how these substances may contribute to diseases like cancer, neurological disorders, and autoimmune conditions. Researchers analysed blood samples from 300 firefighters with high PFAS exposure and found that several genes and biological pathways, many tied to disease development and defense were impacted.

Importantly, the study linked specific types and structures of PFAS, such as PFOS, to changes in genes associated with cancer risk. Some gene changes were also related to Alzheimer’s, lupus, asthma, and other serious illnesses. While not all PFAS compounds affected genes, the research points to potential pathways through which PFAS interfere with our biology.

The findings are an important step toward pinpointing the mechanisms behind PFAS-linked disease, which could aid in future diagnosis and treatment. Pharmaceutical companies are now exploring drugs that can alter gene activity to prevent or lessen PFAS-related health impacts.

Bottom line: Emerging science is showing PFAS exposure can change the way our genes work, increasing the risk for a broad range of diseases and unlocking new avenues for treatment and prevention.
