According to statistics, celiac disease affects approximately 1% of the population worldwide. However, it often goes undiagnosed or misdiagnosed, leading to significant health consequences for those affected.

Symptoms of Celiac Disease

The symptoms of celiac disease can vary widely from person to person. They can range from mild to severe and may include:

• Abdominal pain and bloating
• Diarrhea or constipation
• Unexplained weight loss
• Anemia
• Fatigue and weakness
• Joint pain
• Skin rash
• Delayed growth in children

It’s important to note that some people with celiac disease may not experience noticeable symptoms but still have damage to their small intestine. This is known as silent celiac disease and can be identified through genetic testing.

Importance of HLA Typing in Celiac Disease

HLA typing plays a crucial role in understanding the genetic component of celiac disease. The human leukocyte antigen system, specifically the HLA-DQ2 and HLA-DQ8 genes, is strongly associated with celiac disease susceptibility.
