DESCRIPTION
What is celiac disease?
Celiac disease is an autoimmune disorder in which the immune system mistakenly attacks and damages healthy cells. Individuals with this condition are highly sensitive to gluten, a protein present in wheat, rye, barley, and oats.
When someone with celiac disease consumes gluten, their immune system reacts abnormally, causing severe damage to the lining of the small intestine and leading to various health complications.
It is important to note that this genetic analysis does not require the consumption of gluten. A simple DNA sample from a mouth swab is all that is necessary for an accurate result.
THE GENETICS
Genetic Risk Factors for Celiac Disease
Almost all people with celiac disease have at least one genetic risk allele in their HLA genes. This DNA test detects nucleotide changes that occur in the three CD-associated alleles of the HLA-DQA1 and HLA-DQB1 genes (HLA-DQA1*05, HLA-DQB1*02, HLA-DQB1*0302).
These CD-associated variants can also pair together to form proteins known as DQ2 and DQ8. The presence or absence of these variants gives an indication of the risk of gluten sensitivity and CD. The risk of CD is extremely low if none of these CD-associated alleles are present.
Celiac Disease Risk Based on Genotype
| Patient Genotype (celiac-associated alleles present) | Celiac Disease Risk |
|---|---|
| DQ2 and DQ8 | 1:7 |
| DQ2 and Homozygous HLA-DQB1*02 | 1:10 |
| DQ2 and DQ2 | 1:10 |
| DQ8 and DQ8 | 1:12 |
| DQ8 and HLA-DQB1*02 | 1:24 |
| Homozygous HLA-DQB1*02 | 1:26 |
| DQ2 | 1:35 |
| DQ8 | 1:89 |
| Heterozygous HLA-DQB1*02 | 1:210 |
| HLA-DQA1*05 | 1:1842 |
| No HLA celiac-associated alleles detected | Not at risk of developing celiac disease, less than 1:2518 |
