Systematic population screening programme recommended
|Last review completed
|Next review due in
Screening should be offered to all pregnant women.
The only substantial change made during the 2011 review was that the cut off threshold for all strategies at all stages of pregnancy has been agreed to be set at 1 in 150 at term and this must be implemented from the 1 October 2011.
More about Down's syndrome
Down's syndrome (or 'Down syndrome'), a chromosomal disorder, occurs when, instead of the normal complement of two copies of chromosome 21, there is a whole, or sometimes part of an, additional chromosome 21.
Chromosome abnormalities give rise to specific physical features seen in Down's syndrome. The range of cognitive disabilities as well as other attributes is enormously wide in Down's syndrome. The majority are in the mild range of cognitive ability. Associated defects may include ear and/or eye defects, an increased propensity for infections and heart defects.
