Down Syndrome

Down syndrome is a genetic disorder due to the presence of an extra copy of chromosome 21, resulting in developmental delay, intellectual disability, and characteristic physical features. It is one of the most prevalent chromosomal disorders, affecting about 1 in 700 births globally.

People with Down syndrome tend to have special strengths and challenges, such as different levels of learning disabilities, heart defects, and other medical issues. Early intervention, medical attention, and integrated education make them much better off. Under appropriate care, people with Down syndrome can live productive lives, making significant contributions to their families and communities.

Down syndrome is a genetic disorder due to an extra copy of chromosome 21 (trisomy 21), which influences physical and intellectual development. It is the most prevalent chromosomal condition in the world, found in about 1 in 700 live births. The risk is higher with increasing maternal age, particularly after age 35.

About 6 million individuals have Down syndrome, according to world estimates. In India, it occurs at a rate of 1 in 830 births and has nearly 30,000 new cases every year. There have been advances in medical care that have increased longevity such that it is in excess of 60 years now among developed nations, although healthcare access continues to be challenging in low-resource environments.

Causes of Down Syndrome

Down syndrome is a genetic condition caused by an extra copy of chromosome 21. Normally, humans have 46 chromosomes arranged in 23 pairs, with one set inherited from each parent. In individuals with Down syndrome, abnormal cell division results in an additional full or partial chromosome 21, disrupting normal development. The exact reason why this occurs is unknown, but researchers have identified three main types of Down syndrome based on how the extra genetic material is present:

1. Trisomy 21 (Nondisjunction) – Most Common Cause (95%)

• Trisomy 21 is caused by an error in cell division called nondisjunction.
• During the formation of reproductive cells (egg or sperm), the chromosome pairs fail to separate properly.
• This results in an embryo with three copies of chromosome 21 in every cell, instead of the usual two.
• The risk of nondisjunction increases with maternal age, particularly in women over 35.

2. Translocation Down Syndrome (3-4%)

• In this type, a part of chromosome 21 breaks off and attaches (translocates) to another chromosome, usually chromosome 14.
• The total number of chromosomes remains 46, but the extra piece of chromosome 21 causes Down syndrome characteristics.
• Unlike trisomy 21, translocation can be hereditary, as a parent may carry a balanced translocation (where genetic material is rearranged but no extra material is present).

3. Mosaic Down Syndrome (1-2%)

• This occurs when some cells in the body have the normal 46 chromosomes, while others have an extra chromosome 21.
• This happens due to abnormal cell division occurring after fertilization.
• People with mosaic Down syndrome often have fewer symptoms and milder developmental issues compared to those with full trisomy 21.

Risk Factors for Down Syndrome

While the exact cause of the extra chromosome 21 is not fully understood, certain risk factors increase the likelihood of Down syndrome:

• Maternal Age: Women over 35 have a higher risk of having a baby with Down syndrome. By age 40, the risk is about 1 in 100, and by age 45, it increases to 1 in 30.
• Genetic Translocation: Parents who carry a balanced translocation involving chromosome 21 have an increased risk of passing Down syndrome to their child.
• Previous Child with Down Syndrome: Having one child with Down syndrome slightly increases the risk of having another child with the condition.

Although Down syndrome is a genetic condition, it is not inherited in most cases. Trisomy 21 and mosaic Down syndrome occur due to random errors in cell division, while only translocation Down syndrome has a hereditary component.

Symptoms of Down Syndrome

Down syndrome affects multiple systems of the body, leading to a range of physical, cognitive, and developmental symptoms. While symptoms vary among individuals, some common characteristics are observed.

1. Physical Symptoms

People with Down syndrome often have distinctive physical features, including:

• Flattened facial profile with a small nose and upward-slanting eyes
• Almond-shaped eyes with a fold of skin on the inner corner (epicanthal folds)
• Small head and ears, with a slightly flattened back of the head
• Short neck with excess skin at the nape
• Low muscle tone (hypotonia) leading to delayed motor development
• Short stature with short arms and legs
• Single deep crease across the palm (palmar crease)
• Wide space between the first and second toes (sandal gap deformity)
• Small mouth and protruding tongue due to poor muscle tone

2. Intellectual and Developmental Symptoms

• Mild to moderate intellectual disability (IQ typically ranges from 30-70)
• Delayed speech and language development
• Learning difficulties, with better visual memory than auditory learning
• Short attention span and difficulty with focus
• Slow motor skill development, such as sitting, crawling, and walking
• Social and emotional strengths, often displaying warmth and friendliness

3. Behavioral and Emotional Symptoms

• Stubbornness and difficulty with change
• Impulsivity and trouble understanding consequences
• Tendency to mimic behaviors and learn through repetition
• Increased risk of anxiety, depression, and obsessive-compulsive behaviors

4. Health-Related Symptoms

People with Down syndrome are at risk for various medical conditions, including:

Congenital Conditions

• Heart defects (50%), including atrioventricular septal defect (AVSD)
• Gastrointestinal (GI) disorders, such as duodenal atresia and Hirschsprung’s disease
• Thyroid disorders, particularly hypothyroidism

Hearing and Vision Problems

• Hearing loss due to frequent ear infections or structural differences in the ear
• Vision issues, including nearsightedness, farsightedness, and cataracts
• Increased risk of strabismus (crossed eyes) and nystagmus (involuntary eye movement)

Weakened Immune System and Other Risks

• Higher susceptibility to infections, including pneumonia and respiratory illnesses
• Leukemia risk, with increased likelihood of childhood blood cancers
• Sleep apnea, due to airway obstruction from enlarged tonsils or low muscle tone
• Alzheimer’s disease risk, as many individuals develop early-onset dementia

Despite these challenges, early intervention, medical care, and supportive therapies help individuals with Down syndrome lead fulfilling and meaningful lives.

Diagnosis of Down Syndrome

Down syndrome can be diagnosed before birth (prenatally) or after birth (postnatally) using various screening and diagnostic tests.

1. Prenatal Diagnosis (Before Birth)

Prenatal testing for Down syndrome is divided into screening tests and diagnostic tests.

1. Screening Tests (Estimate the Risk)

Screening tests do not confirm Down syndrome but assess the likelihood of the baby having the condition. They are non-invasive and commonly performed in the first and second trimesters.

1. First-Trimester Screening (10-14 Weeks)

• Ultrasound (Nuchal Translucency Test): Measures fluid at the back of the baby’s neck. Increased fluid may indicate Down syndrome.
• Blood Tests (Pregnancy-Associated Plasma Protein-A (PAPP-A) and Human Chorionic Gonadotropin (hCG)): Abnormal levels may suggest a higher risk.

2. Second-Trimester Screening (15-20 Weeks)

• Quadruple Marker Test (Quad Screen): Measures four pregnancy hormones (AFP, hCG, Estriol, and Inhibin-A). Abnormal levels indicate increased risk.
• Cell-Free DNA Test (Non-Invasive Prenatal Testing – NIPT): Analyzes fetal DNA in maternal blood to detect trisomy 21 with high accuracy (99%).

If screening results indicate a high risk, diagnostic tests are recommended for confirmation.

1. Diagnostic Tests (Confirm the Condition)

Diagnostic tests provide a definitive diagnosis but are invasive and carry a small risk of miscarriage. They analyze fetal chromosomes.

1. Chorionic Villus Sampling (CVS) (10-13 Weeks)

• A small tissue sample is taken from the placenta and examined for extra chromosome 21.
• Risk of miscarriage: ~1%.

2. Amniocentesis (15-20 Weeks)

• A sample of amniotic fluid is collected and analyzed for chromosomal abnormalities.
• More than 99% accurate; miscarriage risk: ~0.1-0.3%.

3. Percutaneous Umbilical Blood Sampling (PUBS) (After 20 Weeks, Rarely Used)

• Fetal blood is taken from the umbilical cord for chromosome analysis.
• Used only in special cases due to higher miscarriage risk.

2. Postnatal Diagnosis (After Birth)

If Down syndrome is suspected at birth based on physical features, it is confirmed through genetic testing.

1. Physical Examination

Doctors look for common physical traits like flat facial profile, almond-shaped eyes, single palm crease, and low muscle tone. However, features alone are not enough for a conclusive diagnosis.

1. Karyotyping (Chromosomal Analysis)

• A blood sample is taken from the baby to analyze the chromosomes.
• If an extra copy of chromosome 21 is present, Down syndrome is confirmed.
• Karyotyping also determines the specific type (Trisomy 21, Translocation, or Mosaic Down Syndrome).

1. Fluorescence In Situ Hybridization (FISH) Test

• A rapid genetic test that detects chromosome 21 abnormalities within a few days.
• Less detailed than karyotyping but useful for quick diagnosis.

1. Microarray or PCR-Based Genetic Tests

• Used in special cases for high-resolution genetic analysis.

Prenatal screening helps identify high-risk pregnancies, while diagnostic tests confirm the presence of Down syndrome. Postnatal genetic testing is essential to confirm the diagnosis after birth. Early diagnosis allows families to plan medical care, therapy, and support systems for the child.

2. Genetic Counseling

• If there is a family history of Down syndrome or a previous child with the condition, consulting a genetic counselor can help assess risks.
• Karyotype testing of parents can check for balanced translocation, a hereditary form of Down syndrome.
• Couples at higher risk may consider alternative reproductive options (e.g., egg donation, preimplantation genetic testing).

3. Preimplantation Genetic Testing (PGT) for IVF

• Couples undergoing in vitro fertilization (IVF) can opt for Preimplantation Genetic Testing (PGT) to screen embryos for chromosomal abnormalities before implantation.
• This method helps select healthy embryos, reducing the chance of Down syndrome.

4. Prenatal Screening and Diagnosis

• Non-Invasive Prenatal Testing (NIPT), ultrasound, and blood tests can identify pregnancies at higher risk.
• If screening results suggest a high probability, confirmatory diagnostic tests (amniocentesis or chorionic villus sampling) can provide definitive results.
• Early diagnosis helps parents prepare for medical and educational support if needed.

While Down syndrome cannot be completely prevented, family planning, genetic counseling, preimplantation genetic testing, and prenatal screening can help reduce the risk and ensure early diagnosis for better management and support.
