Genetics Home Reference : ²⁵ Celiac disease is a condition in which the immune system is abnormally sensitive to gluten, a protein found in wheat, rye, and barley. Celiac disease is an autoimmune disorder; autoimmune disorders occur when the immune system malfunctions and attacks the body's own tissues and organs. Without a strict, lifelong gluten-free diet, inflammation resulting from immune system overactivity may cause a wide variety of signs and symptoms involving many parts of the body. Celiac disease can develop at any age after an individual starts eating foods containing gluten. The classic symptoms of the condition result from inflammation affecting the gastrointestinal tract. This inflammation damages the villi, which are small, finger-like projections that line the small intestine and provide a greatly increased surface area to absorb nutrients. In celiac disease, the villi become shortened and eventually flatten out. Intestinal damage causes diarrhea and poor absorption of nutrients, which may lead to weight loss. Abdominal pain, swelling (distention), and food intolerances are common in celiac disease. Inflammation associated with celiac disease may lead to an increased risk of developing certain gastrointestinal cancers such as cancers of the small intestine or esophagus. Inflammation and poor nutrient absorption may lead to problems affecting many other organs and systems of the body in affected individuals. These health problems may include iron deficiency that results in a low number of red blood cells (anemia), vitamin deficiencies, low bone mineral density (osteoporosis), itchy skin rashes (dermatitis herpetiformis), defects in the enamel of the teeth, chronic fatigue, joint pain, poor growth, delayed puberty, infertility, or repeated miscarriages. Neurological problems have also been associated with celiac disease; these include migraine headaches, depression, attention-deficit/hyperactivity disorder (ADHD), and recurrent seizures (epilepsy). Many people with celiac disease have one or more of these varied health problems but do not have gastrointestinal symptoms. This form of the condition is called nonclassic celiac disease. Researchers now believe that nonclassic celiac disease is actually more common than the classic form. Celiac disease often goes undiagnosed because many of its signs and symptoms are nonspecific, which means they may occur in many disorders. Most people who have one or more of these nonspecific health problems do not have celiac disease. On average, a diagnosis of celiac disease is not made until 6 to 10 years after symptoms begin. Some people have silent celiac disease, in which they have no symptoms of the disorder. However, people with silent celiac disease do have immune proteins in their blood (antibodies) that are common in celiac disease. They also have inflammatory damage to their small intestine that can be detected with a biopsy. In a small number of cases, celiac disease does not improve with a gluten-free diet and progresses to a condition called refractory sprue. Refractory sprue is characterized by chronic inflammation of the gastrointestinal tract, poor absorption of nutrients, and an increased risk of developing a type of cancer of the immune cells called T-cell lymphoma.

MalaCards based summary : Celiac Disease 1, also known as celiac disease, is related to refractory celiac disease and autoimmune disease, and has symptoms including constipation, abdominal pain and diarrhea. An important gene associated with Celiac Disease 1 is HLA-DQB1 (Major Histocompatibility Complex, Class II, DQ Beta 1), and among its related pathways/superpathways are Allograft rejection and Cell adhesion molecules (CAMs). The drugs tannic acid and Benzocaine have been mentioned in the context of this disorder. Affiliated tissues include small intestine to gliadin, small intestine and t cells, and related phenotypes are vitamin b12 deficiency and seizures

Disease Ontology : ¹² An autoimmune disease of gastrointestinal tract that is caused by a reaction located in small intestine to gliadin, a prolamin (gluten protein) found in wheat, and similar proteins found in the crops of the tribe Triticeae. The disease is associated with HLA-DQ gene. It has symptom abdominal pain, has symptom constipation, has symptom diarrhea, has symptom nausea and vomiting, and has symptom loss of appetite.

NIH Rare Diseases : ⁵² Celiac disease is an autoimmune disorder that damages the small intestine and inhibits absorption of nutrients. People with celiac disease cannot tolerate gluten, a protein in wheat, rye, barley, and in some products such as medicines, vitamins, and lip balms. When affected people eat food with gluten, or use a product with gluten, the immune system reacts by damaging tiny parts of the lining of the small intestine called villi. Because villi normally allow the blood to absorb nutrients from food, affected individuals become malnourished. Classic signs and symptoms are caused by inflammation of the gastrointestinal tract and may include diarrhea, weight loss, abdominal pain, swelling, and food intolerance. However, many people have other symptoms involving many body systems, and some people have no symptoms. While celiac disease tends to run in families, it does not follow a specific inheritance pattern. The risk to develop celiac disease is raised by having certain forms of the HLA-DQA1 and HLA-DQB1 genes . Treatment is a lifelong, gluten-free diet.

OMIM : ⁵⁶ Celiac disease, also known as celiac sprue and gluten-sensitive enteropathy (GSE), is a multifactorial disorder of the small intestine that is influenced by both environmental and genetic factors. It is characterized by malabsorption resulting from inflammatory injury to the mucosa of the small intestine after the ingestion of wheat gluten or related rye and barley proteins (summary by Farrell and Kelly, 2002). Long regarded as gastrointestinal disorder of childhood, the disease is now considered to be a chronic systemic autoimmune disease and is more often diagnosed in adults than in children (Monsuur et al., 2005). For a discussion of genetic heterogeneity of celiac disease, see MAPPING. (212750)

MedlinePlus : ⁴² Celiac disease is an immune disease in which people can't eat gluten because it will damage their small intestine. If you have celiac disease and eat foods with gluten, your immune system responds by damaging the small intestine. Gluten is a protein found in wheat, rye, and barley. It may also be in other products like vitamins and supplements, hair and skin products, toothpastes, and lip balm. Celiac disease affects each person differently. Symptoms may occur in the digestive system, or in other parts of the body. One person might have diarrhea and abdominal pain, while another person may be irritable or depressed. Irritability is one of the most common symptoms in children. Some people have no symptoms. Celiac disease is genetic. Blood tests can help your doctor diagnose the disease. Your doctor may also need to examine a small piece of tissue from your small intestine. Treatment is a diet free of gluten. NIH: National Institute of Diabetes and Digestive and Kidney Diseases

KEGG : ³⁶ Celiac disease is a chronic gluten intolerance that occurs in genetically predisposed individuals. The ingestion of gluten causes chronic inflammation of the small intestinal mucosa, leading to nutrient malabsorption. Susceptibility to celiac disease is strongly associated with particular HLA class II alleles. However, non-HLA genetic factors are likely to be required for the development of the disease. It has been reported that CTLA4 and MYO9B gene polymorphisms are associated with predisposition to celiac disease.
