Epigenetics and Celiac: Unlocking New Insights

Over 30% of the population carry the genetic markers HLA-DQ2 or HLA-DQ8. Yet less than 3% will ever develop celiac disease. So, what’s different in those who do?

A 2022 study explores how epigenetics—the science of how behavior and environment influence gene activity—may help answer this question. According to the CDC, epigenetics refers to changes in how your body reads DNA without altering the DNA itself. These changes are reversible and shaped by lifestyle and environment.

Beyond Genetics: Why Some Get Celiac, and Others Don’t

The study suggests that combining epigenetics with machine learning could help:

• Identify individuals more at risk of developing celiac
• Discover potential environmental or biological triggers
• Explore new pathways toward a cure

This research challenges the idea that having the HLA-DQ2 or HLA-DQ8 markers alone determines your fate. Instead, external factors—stress, viral infections, gut microbiome imbalances, infant feeding practices, mode of birth, pregnancy changes, and even gluten exposure timing—might all play a role.

The 99% Connection

While 99% of celiac patients carry at least one of these genetic variants, not everyone with them gets sick. Epigeneticsfocuses on understanding the other factors that influence whether the disease develops.
