Were you looking for information about Down Syndrome? Downsyndroom is a common misspelling of Down syndrome.
Down syndrome is a genetic disorder caused by the presence of an extra 21st chromosome (trisomy 21). It is usually the result of a random event that occurs during the formation of reproductive cells and occurs in 1 out of 800 live births. The disorder is associated with mental retardation, learning disabilities, and a characteristic facial appearance. A diagnosis of Down syndrome can be made during prenatal testing and shortly after birth.
