Edwards syndrome, also known as Trisomy 18, is a genetic disorder resulting from a chromosomal abnormality. With an incidence rate of approximately 1 in 5,000 births, this condition significantly hampers both the growth and development of affected individuals. Unfortunately, there is currently no cure for Edwards syndrome, making its prognosis often devastating.
Understanding Trisomy 18
Trisomy 18, also known as Edwards syndrome, is a genetic condition caused by the presence of an additional copy of chromosome 18. Normally, human cells contain 23 pairs of chromosomes, which carry the genetic material inherited from both parents. Each chromosome is typically present in two copies, including chromosome 1, chromosome 2, and so on. However, individuals with Trisomy 18 have three copies of chromosome 18, leading to the development of this condition. Trisomy 18 is the medical term used to describe this chromosomal abnormality.
Causes of Edwards Syndrome
The causes of Edwards syndrome are primarily attributed to random events occurring during the formation of reproductive cells. One of the main causes is an error in cell division known as nondisjunction, which leads to the development of a reproductive cell (such as a sperm or egg cell) with an additional copy of chromosome 18. It is important to note that Edwards syndrome is typically not hereditary and is not influenced by any actions taken or not taken by the parents prior to or during the pregnancy. However, it is worth mentioning that older parents may have a slightly higher risk of conceiving a baby with this condition.
