DALLAS – Feb. 19, 2026 – People often remark that allergies run in their family, but the genetic causes have remained unclear. Previous food allergy genetic research has relied upon broad but surface-level methods called genome-wide association studies.
Now, for the first time, a study at UT Southwestern Medical Center uses an in-depth genetic approach to explain why food allergies are inherited and why some people develop multiple food allergies. The findings, published in The Journal of Allergy and Clinical Immunology, suggest that more comprehensive genetic testing could support better approaches to diagnosing and treating food allergies.
“This research shows that advanced DNA testing can uncover clear genetic causes in nearly 4 out of 10 people with multiple food allergies,” said…
