What is Trisomy 18?
Trisomy 18 is a rare chromosomal disorder caused by the presence of an extra chromosome 18 in each cell of the body. It is also called Edward Syndrome, in honor of the British physician who first identified the condition in 1960. It is associated with severe health problems and physical and mental disabilities, and a very small proportion of children born with the condition survive to adulthood.

Signs and Symptoms of Trisomy 18
Children with Trisomy 18 typically experience a variety of physical and mental problems. Common physical features include a large head size, low birth weight, and problems with the heart, kidneys, and other organs. In addition, muscles tend to be weak and babies often have an unusually shaped chest. Problems with the digestive system are also common. Mental and developmental delays are also common in children with Trisomy 18.

Life Expectancy
Trisomy 18 is a very serious condition and the life expectancy is usually very short. The majority of children with T18 die within the first few weeks or months of life, but some may live into adulthood. Those who survive the first few months or years are likely to experience severe medical problems throughout their life.

To increase the quality of life for these individuals, medical and educational assistance can be provided. Additionally, genetic counseling and pre-birth testing can help families prepare for the unique challenges associated with this condition. With the appropriate medical treatment, children born with Trisomy 18 can potentially lead meaningful lives.
