Specialized testing of chromosome 15 will be required; the usual tests done during amniocentesis or chorionic villi sampling will not reveal the specific, small genetic flaw that causes Angelman syndrome.
For people with celiac disease, when gluten-containing foods are eaten, your body responds by attacking the villi, so rather than having all this surface area to absorb nutrients, the opposite occurs.
If you've researched celiac disease symptoms, you've likely heard references to the small intestine and villi, but may not understand the role they play and why they are important for optimal health.
When a person with celiac disease ingests gluten, his or her immune system attacks the villi within the small intestine, resulting in an inability for nutrients from food to enter the bloodstream.
These patients will usually not show elevated anti-gliadin antibodies or characteristically damaged villi, and as a result may be advised that their symptoms are not related to gluten sensitivity.
