About Edward's Syndrome (Trisomy 18)

What is Edwards Syndrome

Trisomy 18, also known as Edwards syndrome, is a genetic condition where there is an extra copy of chromosome 18 in some or all of the body's cells. This additional chromosome can affect the development of a fetus and lead to characteristic features of the condition. Infants with Trisomy 18 may experience complications before birth or in early childhood, and unfortunately, many do not survive. However, some children with Trisomy 18 can live for several years. The incidence of Trisomy 18 is estimated to be around 1 in 5,000 live-born infants, with a higher occurrence during pregnancy. While the chances of having a child with Trisomy 18 increase with age, it can occur at any age.

Causes and Risk Factors

Trisomy 18, also known as Edwards syndrome, is caused by the presence of an extra copy of chromosome 18. The pathophysiologic causes of Trisomy 18 include:

Random occurrence: In most cases, the extra chromosome 18 happens randomly during conception when the sperm meets the egg, due to an error in cell division where chromosomes do not separate properly. It is not influenced by any specific factors.

Translocation: In rare cases, parts of chromosome 18 may break off and attach to other chromosomes. This can occur randomly or through a balanced translocation, where one parent has an atypical set of chromosomes that are balanced and do not cause medical issues.

Maternal age is a key risk factor for Trisomy 18. While it can occur in younger mothers, the risk increases with age.

It's important to note that Trisomy 18 is a complex genetic condition, and further research is needed to fully understand its causes and risk factors. If you have concerns about Trisomy 18 or any genetic condition, it's best to consult with a healthcare professional for personalized advice.

Symptoms of Edwards Syndrome

Trisomy 18, also known as Edwards syndrome, is a chromosomal disorder that can cause various symptoms. Common symptoms of Trisomy 18 include:

Slow growth before birth (intrauterine growth retardation)
Low birth weight
Small, abnormally shaped head
Small jaw and mouth
Clenched fists with overlapping fingers

Additional symptoms may include:

Congenital heart defects
Various abnormalities of other organs
Feeding or sucking difficulties
Trouble gaining weight (failure to thrive)
Developmental delays
Intellectual disability
Respiratory problems
Eye or vision issues
Seizures
Gastrointestinal issues

It's important to note that the severity and combination of symptoms can vary among individuals with Trisomy 18. If you suspect your child may have Trisomy 18 or have concerns about their development, it's crucial to consult with a healthcare professional for an accurate diagnosis and appropriate management.

Diagnosing Edwards Syndrome

Trisomy 18 may be detected during pregnancy as part of, prenatal screening and diagnostic testing with done with chorionic villous sampling and amniocentesis.

It's important to note that the specific examinations, tests, and procedures may vary depending on individual cases and symptoms. It's recommended to consult with your healthcare provider for personalized guidance.

Treatment Options

The goals of treatment for Trisomy 18 are focused on improving the quality of life and is often supportive and palliative, depending on severity and family goals.

It's important to note that treatment plans for Trisomy 18 are individualized based on each person's unique needs and circumstances. Consult with a healthcare professional for personalized recommendations.
