Edward Syndrome
Edward Syndrome (pronounced: ed-ward sin-drohm), also known as Trisomy 18, is a genetic disorder caused by the presence of an extra 18th chromosome. The syndrome is named after the British geneticist John Hilton Edwards who first described it in 1960.
Etymology
The term "Edward Syndrome" is derived from the name of John Hilton Edwards, who was the first to identify the syndrome. The term "Trisomy" refers to the presence of an extra chromosome, in this case, the 18th chromosome.
Symptoms
Edward Syndrome is characterized by a number of physical abnormalities and severe developmental delays. These may include:
- Heart defects
- Kidney abnormalities
- Microcephaly (small head)
- Micrognathia (small jaw)
- Clenched hands
- Feeding difficulties
- Growth retardation
Diagnosis
Diagnosis of Edward Syndrome can be made prenatally through Amniocentesis or Chorionic villus sampling. Postnatal diagnosis can be made through a Karyotype test.
Treatment
There is no cure for Edward Syndrome. Treatment is supportive and depends on the specific symptoms and severity in each individual. This may include Physical therapy, Occupational therapy, and Speech therapy.
Prognosis
The prognosis for individuals with Edward Syndrome is generally poor, with many infants not surviving beyond the first year of life. However, some individuals with less severe forms of the syndrome may live into adolescence or early adulthood.
