Trisomy 21, commonly known as Down syndrome, is a genetic condition characterized by the presence of an extra copy of chromosome 21. This additional genetic material can lead to various intellectual and physical disabilities, including distinctive facial features, short stature, and developmental delays. Despite these challenges, individuals with Down syndrome can lead fulfilling lives with appropriate support and care. This blog aims to provide a comprehensive understanding of Trisomy 21, its causes, detection methods during pregnancy, and its impact on individuals and families in Dubai and the broader UAE.

What is Trisomy 21?

Trisomy 21 occurs when an individual has three copies of chromosome 21 instead of the typical two. This genetic anomaly can lead to various degrees of intellectual disability and physical characteristics, including:

A characteristic facial appearance: Flat facial profile, upward-slanting eyes
Short stature
Developmental delays and learning difficulties

People with Down syndrome in UAE have a wide range of abilities and can achieve significant milestones with the right support. Down syndrome is the most common genetic cause of intellectual disability and affects individuals across all races and ethnicities.

Causes of Trisomy 21 in Dubai

Trisomy 21 is caused by the presence of an extra copy of chromosome 21 in some or all of an individual’s cells. There are three primary types of Trisomy 21:

Non-Disjunction: This is the most common cause, occurring when chromosomes fail to separate properly during cell division. This type accounts for about 95% of all Down syndrome cases. Learn more about non-disjunction.
Mosaicism: Mosaicism occurs when only some of the individual’s cells have an extra copy of chromosome 21. This can result in a milder form of Down syndrome with fewer symptoms. Mosaicism accounts for about 1-2% of cases. Explore mosaicism.
Translocation: In this type, part of chromosome 21 attaches to another chromosome. It is usually inherited from one of the parents and accounts for about 3-4% of cases. Read about translocation.

Risk Factors for Down Syndrome in Dubai

While Trisomy 21 can affect any individual, the risk of having a baby with Down Syndrome increases with maternal age. Women aged 35 and older have a higher chance of giving birth to a child with Down Syndrome. However, it is important to note that the condition can occur in individuals of any race or ethnicity, and there is currently no way to prevent Trisomy 21.

Detection Methods for Down Syndrome During Pregnancy in Dubai

Several methods help detect Down Syndrome during pregnancy, enabling parents to make informed decisions:

1. Prenatal Screening Tests:

These include ultrasound scans and blood tests to assess the risk of Down Syndrome.

Ultrasound Scans: Can detect physical signs that may indicate an increased risk of Down Syndrome, such as increased nuchal translucency.
Blood Tests: The combined first-trimester screening or the quadruple screen measure specific substances in the mother’s blood to assess the risk of Down Syndrome. These tests are not diagnostic and cannot confirm the presence of the condition but can indicate an increased likelihood.

2. Diagnostic Tests:

CVS (Chorionic Villus Sampling) and amniocentesis provide definitive diagnoses but carry a small miscarriage risk.

Chorionic Villus Sampling (CVS): Involves removing a small sample of the placenta to analyze fetal cells and determine the number of chromosomes present.
Amniocentesis: Involves taking a sample of amniotic fluid to analyze fetal cells. Both CVS and amniocentesis are highly accurate diagnostic tests but carry a small risk of miscarriage.

3. Non-Invasive Prenatal Testing (NIPT):

A blood test from the mother that detects fetal DNA with high accuracy. NIPT is highly accurate and can be performed as early as 10 weeks into pregnancy. Although it is considered a screening test and not diagnostic, it can provide a high level of confidence in assessing the risk of Down Syndrome in Dubai. If NIPT results suggest the possibility of Down Syndrome, a diagnostic test such as CVS or amniocentesis may still be needed to confirm the diagnosis.
