Were you looking for information about Down Syndrome? Down syndroom is a common misspelling of Down syndrome.
Down syndrome, a genetic disorder, is caused by an additional chromosome 21 (trisomy 21). It is the most frequent genetic cause of mild to moderate mental retardation and associated medical problems. People with the disorder are at an increased risk for developing hearing problems, leukemia and other cancers, and Alzheimer's disease. Although there is no cure for Down syndrome, treatments are available to control symptoms and treat medical conditions that occur as a result.
