Question 1

What is Down syndrome?

Accepted Answer

Down syndrome is a genetic condition caused by an extra copy of chromosome 21, resulting in developmental delays and distinctive physical features. It is caused by a chromosomal abnormality called trisomy 21 that occurs during cell division. The Alpha-Fetoprotein (AFP) blood test is the most important prenatal screening test for assessing Down syndrome risk during pregnancy.

Question 2

What causes Down syndrome?

Accepted Answer

Down syndrome is caused by the presence of an extra copy of chromosome 21, a condition called trisomy 21. This chromosomal abnormality occurs during the formation of reproductive cells when the genetic material fails to separate properly during cell division. The extra chromosome affects how the baby's body and brain develop, leading to the physical and intellectual characteristics associated with Down syndrome. While the exact reason why this chromosomal error occurs is not fully understood, maternal age is a known risk factor, with the likelihood increasing as a woman gets older, particularly after age 35.

Question 3

What is the best test for Down syndrome?

Accepted Answer

The Alpha-Fetoprotein (AFP) blood test is the most important prenatal screening test for assessing Down syndrome risk because it measures a specific protein produced by the developing fetus that passes into the mother's bloodstream. Lower than normal AFP levels can indicate an increased risk of Down syndrome and other chromosomal abnormalities. This test is typically performed between 15 and 20 weeks of pregnancy and is often combined with other blood markers like hCG and estriol as part of a comprehensive prenatal screening panel called the triple or quad screen. While these screening tests assess risk rather than provide a definitive diagnosis, they help identify pregnancies that may benefit from additional diagnostic testing such as amniocentesis or chorionic villus sampling.

Question 4

When should I get tested for Down syndrome?

Accepted Answer

You should get tested if you are pregnant and want to assess your baby's risk for chromosomal abnormalities, especially if you are over 35 years old or have a family history of genetic conditions. The AFP screening test is typically performed between 15 and 20 weeks of pregnancy, while first-trimester screening options are available between 10 and 13 weeks. Early screening allows time for additional diagnostic testing if needed and helps you and your healthcare provider make informed decisions about prenatal care. Women of any age can choose to have prenatal screening, as Down syndrome can occur in any pregnancy regardless of maternal age or family history.

Question 5

What are the symptoms of Down syndrome?

Accepted Answer

Down syndrome is characterized by distinctive physical features including a flattened facial profile, upward slanting eyes, a short neck, small ears, and a single deep crease across the palm of the hand. Children with Down syndrome typically experience mild to moderate intellectual disability and developmental delays in reaching milestones like sitting, walking, and talking. They may also have low muscle tone (hypotonia), which can affect motor skills and physical development. Many individuals with Down syndrome have a cheerful, affectionate disposition and strong social skills. Associated health conditions can include heart defects present at birth, gastrointestinal problems, hearing loss, vision problems, and an increased risk of certain infections and medical conditions.

Question 6

Who is at risk for Down syndrome?

Accepted Answer

All pregnant women have some risk of having a baby with Down syndrome, but the likelihood increases significantly with maternal age. Women who become pregnant at age 35 or older face a higher risk, with the probability rising from about 1 in 1,500 at age 20 to 1 in 350 at age 35, and 1 in 100 by age 40. Parents who have already had one child with Down syndrome or who carry a genetic translocation involving chromosome 21 also have an increased risk. However, because younger women have more babies overall, the majority of children with Down syndrome are actually born to mothers under 35. Paternal age may also play a minor role, though maternal age remains the most significant known risk factor.

Question 7

What happens if Down syndrome is not detected before birth?

Accepted Answer

If Down syndrome is not detected during prenatal screening, it is typically diagnosed shortly after birth based on the baby's physical features and confirmed through a blood test called a karyotype that examines the chromosomes. Early diagnosis is beneficial because it allows families to connect with support services, early intervention programs, and specialized medical care right from the start. Children with Down syndrome benefit significantly from early intervention therapies including physical therapy, speech therapy, and occupational therapy that can help maximize their developmental potential. Without early detection, there may be delays in accessing these critical services, though children can still make excellent progress once appropriate support is in place. Many individuals with Down syndrome lead fulfilling lives with proper medical care, education, and family support.

Question 8

Can Down syndrome be diagnosed with a blood test?

Accepted Answer

Blood tests can screen for Down syndrome risk during pregnancy but cannot provide a definitive diagnosis on their own. The AFP blood test and other prenatal screening panels measure specific proteins and hormones in maternal blood that indicate increased risk of chromosomal abnormalities. Abnormal screening results indicate that further diagnostic testing is recommended, such as non-invasive prenatal testing (NIPT), which analyzes fetal DNA in maternal blood with high accuracy, or invasive procedures like amniocentesis or chorionic villus sampling that examine fetal chromosomes directly. After birth, a blood test called a karyotype definitively diagnoses Down syndrome by analyzing the baby's chromosomes to confirm the presence of an extra chromosome 21.

Question 9

How is Down syndrome treated?

Accepted Answer

Down syndrome itself cannot be cured or treated, but comprehensive care and early intervention can significantly improve quality of life and developmental outcomes. Treatment focuses on managing associated health conditions, providing developmental support through early intervention programs, and ensuring access to appropriate educational services. Many children with Down syndrome benefit from physical therapy to improve strength and motor skills, speech therapy to enhance communication abilities, and occupational therapy to develop daily living skills. Medical management includes regular monitoring and treatment for common associated conditions like heart defects, thyroid problems, hearing and vision issues, and gastrointestinal problems. With appropriate support, therapies, and educational opportunities, individuals with Down syndrome can achieve their potential and lead meaningful, productive lives.

Question 10

How can I prevent Down syndrome?

Accepted Answer

Down syndrome cannot be prevented, as it results from a random chromosomal error that occurs during cell division and is not caused by anything parents did or did not do during pregnancy. While maternal age is the most significant known risk factor, Down syndrome can occur in pregnancies at any maternal age, and most cases happen spontaneously without any identifiable cause. Women who become pregnant at a younger age have a statistically lower risk, but this should not be the sole factor in family planning decisions. Genetic counseling before pregnancy can help couples understand their specific risks, particularly if there is a family history of chromosomal abnormalities or if parents carry a chromosomal translocation. Prenatal screening and diagnostic testing can detect Down syndrome during pregnancy, allowing families to prepare and connect with resources.

Question 11

What can I do to prepare if my baby might have Down syndrome?

Accepted Answer

If prenatal screening indicates an increased risk of Down syndrome, connecting with resources and support networks early can help you prepare emotionally and practically. Consider meeting with a genetic counselor who can explain test results, discuss diagnostic testing options, and provide accurate information about what Down syndrome means for your child's future. Reaching out to parent support groups and Down syndrome organizations can connect you with families who have firsthand experience and can offer valuable insights and encouragement. Learn about early intervention programs available in your area, as these services can begin shortly after birth and significantly impact your child's development. Many families find that educating themselves about Down syndrome, visiting with healthcare specialists like pediatric cardiologists, and creating a supportive network helps them feel more confident and prepared to welcome their baby.
