A disease which may result from Down syndrome

The correct option is Celiac disease.

Down syndrome (Trisomy 21) is a genetic disorder associated with a wide range of systemic complications and an increased susceptibility to autoimmune conditions. Among the options provided, celiac disease has a well-documented and strong clinical association with Down syndrome.

Celiac disease is a chronic autoimmune enteropathy triggered by the ingestion of gluten in genetically predisposed individuals. Individuals with Down syndrome are at a significantly higher risk of developing celiac disease compared to the general population. While the prevalence of celiac disease in the general population is approximately 1%, it is estimated to be between 5% and 15% in individuals with Down syndrome. Due to this high correlation, routine screening for celiac disease is standard clinical practice for individuals diagnosed with Down syndrome.
