Chronic enteropathy associated with SLCO2A1 gene

Chronic enteropathy associated with SLCO2A1 gene (also known as CEAS or chronic nonspecific multiple ulcers of the small intestine, CNSU) is a rare inherited digestive disorder caused by mutations in the SLCO2A1 gene. This gene provides instructions for making a protein that helps transport prostaglandins, which are important chemical messengers involved in inflammation and tissue repair in the gut lining. When this transporter does not work properly, prostaglandins build up in the intestinal wall, leading to chronic inflammation and the formation of multiple ulcers, primarily in the small intestine. Patients typically experience persistent or recurring abdominal pain, chronic diarrhea, blood in the stool, and iron-deficiency anemia that does not respond well to standard treatments. Over time, the ongoing blood loss and poor nutrient absorption can lead to significant weight loss, fatigue, and protein deficiency. Some patients may also develop thickening of the fingers (digital clubbing) and small bowel strictures that can cause intestinal obstruction. There is currently no cure for this condition. Treatment focuses on managing symptoms, correcting anemia with iron supplements or transfusions, ensuring adequate nutrition, and sometimes using medications to reduce inflammation. In severe cases where strictures or blockages develop, surgery may be needed to remove damaged sections of the intestine. The condition was initially described predominantly in East Asian populations, particularly in Japan, though cases have been identified in other regions as well.
