Were you looking for information about Down Syndrome? Down syndrom is a common misspelling of Down syndrome.
Down syndrome is a genetic disorder that is associated with mental retardation, poor muscle tone, and a characteristic facial appearance. It is caused by an additional chromosome 21 (trisomy 21), which is usually the result of a random event that occurs during the formation of reproductive cells. People with Down syndrome are at an increased risk of developing certain medical conditions, such as thyroid problems, developmental delay, and congenital heart disease.
