Down Syndrome Education International. DSE works to improve early intervention and education for children with Down syndrome everywhere. We support scientific research and provide evidence- based resources and services to help over 1. DSE transforms the lives of young people with Down syndrome by improving understanding of their learning needs and by helping families and professionals to provide effective support, early intervention and education.
Our goal is to improve outcomes for all children with Down syndrome, helping them to lead more independent, productive and fulfilling lives.

Down syndrome (DS or DNS) or Down's syndrome, also known as trisomy 21, is a genetic disorder caused by the presence of all or part of a third copy of chromosome 21. [1]. Down syndrome is a condition in which a person has an extra chromosome. Chromosomes are small “packages” of genes in the body. Babies with Down syndrome have an.

Down syndrome is a condition in which a person is born with an extra copy of chromosome 21. People with Down syndrome can have physical problems, as well as.
Wrongful deaths and rightful lives – screening for Down syndrome. Frank Buckley and Sue Buckley. Prenatal screening for Down syndrome affects millions of pregnancies every year worldwide. The vast majority of screen- positive results are false, yet encourage invasive diagnostic procedures that pose additional risks to unborn babies.
As a direct consequence many babies who do not have Down syndrome are lost. We estimate that current screening practice in England and Wales reduces annual live births of babies with Down syndrome by around 6. Down syndrome. Although prenatal diagnoses are becoming more frequent, more babies with Down syndrome are being born (up 2. Considerable attention has been given to studying the performance of competing screening techniques, yet relatively little attention has been given to the consequences for the psychological and physical wellbeing of all parents and their babies.
Meanwhile, quality of life for people with Down syndrome continues to improve. In many countries, people with Down syndrome are living longer and achieving more than ever before.
The authors urge policymakers to note that the live birth prevalence of Down syndrome continues to rise and that average life expectancy is now approaching 6. Accordingly, research and practice priorities should shift from prevention to improving care, education and support for a growing and ageing population. We suggest that policies permitting genetic screening for mental or physical abilities should be reviewed through wide public debate before new prenatal diagnosis and genome sequencing technologies become more readily available.

Currently, Down syndrome would affect an estimated 1 in 5. England and Wales in the absence of screening.

Many of the biochemical markers used in screening are the. Concerns have been noted about the roles of individuals in screening. The main drive towards introducing screening appears to come from medical agencies. Britain. Policies are formulated by advisory committees.
Medical reports emphasize the prevention of suffering and. Public. health reports stress economic aims: to reduce the 'life time costs of care' for. Down's syndrome; to avoid costly litigation for 'wrongful birth' of.
So what are the facts about current screening practices? Prenatal screening in theory.
Maternal age is a clear predictor of the risk of delivering a baby who has Down. Figure 1). Historically, invasive diagnostics were. Down syndrome to be greater. For these mothers, the chance of delivering a baby with Down syndrome. The 'rationale' to this approach was that as long as the chance of giving.
Down syndrome is near to or greater than the risk of losing. In the 1. 98. 0s, it was discovered that the levels of certain substances present in. Down syndrome. This led to efforts to improve on screening based on maternal age. Since then, various combinations of markers.
Down syndrome[3,2. By definition, screening tests estimate the chance of having a baby with Down syndrome. These estimates are categorised into 'screen- positive' (high risk) and 'screen- negative'.
There are. therefore, four possible screening outcomes: true screen- positives, false screen- positives. Figure 2). Mothers receiving screen- positive results. As these procedures risk.
At the same time, they seek to maximise detection rates. The 'risk cut- off' chosen to distinguish between screen- positives and screen- negatives. Figure 3a). A higher risk cut- off reduces false.
Figure 3b). This. In practice. women who have chosen prenatal screening may be more inclined to opt for invasive. Distinguishing between detection and prevention. The presence of an unusual number of chromosomes is surprisingly common among human.
Many fail to survive during the early weeks of pregnancy. Pregnancies affected by. Down syndrome are substantially more likely to miscarry naturally than unaffected. Studies have reported differing estimates of the rates of pregnancy.
A summary estimate suggests that 4. Down syndrome. at around 1. Loss rates appear to be higher among older mothers[2. It is difficult to establish precise figures in the absence of studies including.
It seems probable that miscarriages are more often underreported than terminations. Pregnancies affected by Down syndrome that are not prenatally detected. The natural loss rate means that prenatal detection and termination is not the same. The natural loss rate also means that screening earlier in pregnancy. Estimating risks to unborn babies. The best available evidence suggests that the risk of pregnancy loss due to amniocentesis.

Policies leading to increased first- trimester screening (and therefore diagnosis. CVS)[2,3] may substantially increase the. Performance in practice. Many published studies of competing screening technologies model the effects of. Modelling may or may not be representative of performance. For example, the predicted performance of quadruple test screening.

UK hospitals observed an 8. These modest differences equate to 2 additional unaffected babies lost and 5 fewer. Other studies. also illustrate how outcomes in practice may differ from some models[3. In the UK and many parts of Europe, prenatal screening has been offered to most. In England and Wales, prenatal screening has been available since the end of the.
