Almost all of people who have celiac disease carry a gene for the disease that can be passed on to their children. If you, your partner or your child’s sibling has celiac disease, genetic testing can help figure out if your child can possibly develop celiac disease in the future. This handout can help you learn more about genetic testing for celiac disease and whether your child should have testing for the disease.
Yes, celiac disease can be passed on to your children if you or your partner carry a gene for the disease. But, carrying a gene doesn’t mean your child will definitely have celiac disease. It means your child is at risk of developing celiac disease.
There are 2 genes for celiac disease. These genes are called human leukocyte antigen (HLA) DQ2 and DQ8. Many people who have celiac disease have at least 1 of these genes. In very rare cases, a person won’t have these genes, but might develop celiac disease anyway.
Doctors will test your child for the genes through a blood test.
Genetic testing can help your child by figuring out if he/she:
In many cases, no, genetic testing for celiac disease is not covered by insurance. The testing can be expensive. If you want your child to have genetic testing for celiac disease, you should call your insurance company to ask about the cost and coverage of the test.
The insurance company might ask for the Current Procedural Terminology (CPT) codes or International Code for Diseases (ICD). The current CPT codes are 81376 and 81382. The ICD is K90.0.
