To provide you with the best possible care, we’d like to understand more about your pregnancy journey:
Are you considering screening for chromosomal congenital abnormalities?
- Do you have any concerns or family history of genetic conditions that may affect your baby’s health?
- Are you aware of the importance of early screening for chromosomal congenital abnormalities?
- Do you have any questions or fears about the screening process and its implications for your baby’s health?
Your responses will enable us to tailor a personalised screening plan that addresses your unique needs and aspirations for a healthy pregnancy.
Understanding Chromosomal Congenital Abnormalities: Caring for Your Baby's Health
Chromosomal congenital abnormalities are genetic conditions that occur due to changes or abnormalities in the baby’s chromosomes. These changes can impact the baby’s development and may lead to physical or intellectual disabilities. Detecting these abnormalities early can help you make informed decisions about your pregnancy and prepare for the care your baby may need after birth.
Common Chromosomal Congenital Abnormalities:
Down Syndrome (Trisomy 21): This condition results from an extra copy of chromosome 21, leading to developmental delays and characteristic facial features.
Edwards Syndrome (Trisomy 18): Edwards syndrome is caused by an extra copy of chromosome 18 and is associated with severe developmental and physical abnormalities.
Patau Syndrome (Trisomy 13): Patau syndrome is caused by an extra copy of chromosome 13 and results in severe physical and intellectual disabilities.
The Screening Process: Nurturing Your Baby's Health from the Start
Early screening for chromosomal congenital abnormalities is an essential part of your prenatal care, and we’re dedicated to providing expert guidance and support throughout the process.
**1. Non-Invasive Prenatal Testing (NIPT):
NIPT is a simple blood test that can be performed as early as 10 weeks of pregnancy. It screens for common chromosomal congenital abnormalities with high accuracy and a low risk of complications.
**2. First Trimester Combined Screening:
The first-trimester combined screening involves a blood test and an ultrasound measurement to assess the risk of chromosomal congenital abnormalities. It is usually performed between 11 to 14 weeks of pregnancy.
**3. Chorionic Villus Sampling (CVS) and Amniocentesis:
If NIPT or first-trimester screening indicates an increased risk of chromosomal abnormalities, further testing such as CVS or amniocentesis may be recommended to provide a definitive diagnosis.

FAQ
Ultrasound screenings utilise sound waves to create images of the developing fetus within the womb, enabling healthcare providers to observe its development. These screenings can detect certain congenital anomalies, such as spina bifida.
A screening test for Down’s syndrome, Edwards’ syndrome, and Patau’s syndrome can be performed between weeks 10 and 14 of pregnancy. This test, known as the combined test, includes both an ultrasound scan and a blood test. The blood test is typically conducted alongside the 12-week ultrasound.
Chorionic Villus Sampling (CVS) and amniocentesis are diagnostic procedures used to determine if a baby has chromosomal abnormalities. CVS involves taking a sample from the placenta, while amniocentesis involves sampling the amniotic fluid. Both tests carry a risk of pregnancy loss, ranging from 0.5% to 1%.
Cell-free fetal DNA testing, also known as non-invasive prenatal testing, analyses your blood to detect fetal DNA. This test identifies chromosomal conditions such as Down syndrome, trisomy 13, and trisomy 18. It can be performed as early as 10 weeks into the pregnancy or at a later stage.
Daily intake of a prenatal vitamin containing at least 400 micrograms of folic acid can help reduce the risk of various birth defects. It is recommended to start taking these vitamins if you are of reproductive age, when actively trying to conceive, or as soon as you confirm your pregnancy.
To verify if your baby has this condition, an ultrasound is typically performed around 20 weeks of pregnancy. Additionally, screening tests for chromosomal abnormalities will consider your age as a factor.
Signs of chromosomal abnormalities during pregnancy may include abnormal ultrasound findings, such as structural anomalies or growth issues. Miscarriage before the 20th week of pregnancy and stillborn or death of a baby before the 20th week of pregnancy, are early signs.
Risk factors for chromosomal abnormalities include advanced maternal or paternal age, a family history of genetic disorders, the presence of a chromosomal abnormality in one of the prospective parents, a history of miscarriage or stillbirth, or having previously had a child with a birth defect.
Chromosomal abnormalities are responsible for approximately 50% of miscarriages that occur during the first trimester (up to 13 weeks) of pregnancy. Chromosomes are small structures within cells that contain genes, which govern physical traits such as sex, hair and eye colour, and blood type.
Folic acid is crucial for the healthy development of a fetus, as it helps prevent chromosomal abnormalities. These abnormalities arise from defects in chromosome number or structure during fetal development, which can occur if the fetus does not receive adequate nutrients.
In most instances, miscarriages cannot be prevented and are typically caused by chromosomal abnormalities that hinder the fetus’s development. Recurrent miscarriages are relatively rare, occurring in only about 1% of individuals who have experienced a first miscarriage.
Major chromosomal abnormalities occur in about 1 in 140 live births, translating to an incidence of approximately 0.7%. The likelihood of having a child with a chromosomal abnormality rises with maternal age, ranging from 0.2% at age 20 to 12.5% by age 49.
As a woman ages, the probability that her eggs will have an extra copy of chromosome 21 increases substantially. Consequently, older women have a higher likelihood of giving birth to a baby with Down syndrome compared to younger women.
The primary factor influencing the genetic quality of your eggs is your age. In your 20s, most of your eggs are likely to be genetically normal, though some may be abnormal. However, by your 40s, the majority of your eggs are typically abnormal, regardless of other lifestyle factors.
Parents with chromosomal rearrangements face a higher risk of experiencing additional miscarriages or having children with health issues. However, it is still possible for them to have healthy children.
After an antenatal diagnosis of a chromosomal anomaly or disability, you have two options: continue with the pregnancy or terminate it. The decision to terminate will depend on the gestational age of the pregnancy and the legal regulations in your region.
