Coeliac disease is a chronic autoimmune condition where consuming gluten triggers an immune response that damages the small intestine lining. It is caused by an abnormal immune reaction to gluten proteins found in wheat, barley, and rye, particularly in individuals carrying specific HLA-DQB1 genetic variants. The HLA-DQB1 Low Resolution test is the most important genetic test for assessing coeliac disease risk and ruling out the condition.
Coeliac disease is caused by an abnormal immune reaction to gluten proteins found in wheat, barley, and rye. When people with coeliac disease eat gluten, their immune system mistakenly attacks the lining of the small intestine, specifically damaging the villi (tiny finger-like projections that help absorb nutrients). This autoimmune response is triggered in individuals who carry specific genetic variations in the HLA-DQB1 gene, though having these genes alone doesn't guarantee the disease will develop. Environmental factors, such as infections or stress, may also play a role in triggering the condition in genetically predisposed individuals.
The HLA-DQB1 Low Resolution test is the most important genetic test for coeliac disease because it identifies the specific gene variants present in approximately 95% of people with the condition. This test is particularly valuable for ruling out coeliac disease, as the absence of these genetic markers makes the condition highly unlikely. While the HLA-DQB1 test assesses genetic predisposition, a complete diagnosis typically requires additional blood tests measuring coeliac-specific antibodies (tissue transglutaminase antibodies and endomysial antibodies) along with an intestinal biopsy to confirm damage to the small intestine. The genetic test is especially useful for family members of those with coeliac disease to assess their risk and for cases where other tests are inconclusive.
You should get tested if you experience persistent digestive symptoms like diarrhea, bloating, abdominal pain, or unexplained weight loss. Testing is also recommended if you have a family history of coeliac disease, since first-degree relatives have a 10% chance of developing the condition. Other reasons to get tested include unexplained anemia, fatigue, bone or joint pain, skin rashes (especially dermatitis herpetiformis), or other autoimmune conditions like type 1 diabetes or thyroid disease. It's crucial to continue eating gluten-containing foods before and during testing, as avoiding gluten can lead to false-negative results and make diagnosis difficult.
What this means
Your HLA DQB1 test shows you carry the DQ2 genetic variant, which is associated with increased susceptibility to celiac disease. While this indicates genetic predisposition, it does not mean you have or will definitely develop celiac disease - about 30-40% of the general population carries these genes, but only 1-3% develop the condition. This result means celiac disease cannot be ruled out and further antibody testing may be recommended if you have symptoms.
Recommended actions
Do not start a gluten-free diet before getting celiac antibody testing, as it can affect accuracy
Discuss celiac antibody blood tests with your doctor if you have digestive symptoms
Monitor for symptoms like chronic diarrhea, bloating, fatigue, or unexplained weight loss
Share this genetic information with family members, as celiac disease can run in families
