What is Edwards syndrome?
Edwards syndrome is named after John H. Edwards, a British physician and geneticist who, in 1960 and at the University of Wisconsin, described the disorder. It is an autosomal aneuploidy (a chromosomal abnormality in the non-sex chromosomes, the autosomal ones) caused by an extra copy of chromosome 18.
Causes
The causes of Edwards syndrome are very clear: having extra material from chromosome 18. It is this extra material from autosomal chromosome number 18 that causes serious physiological problems during fetal and infant development that lead to the disease.
Symptoms
Edwards syndrome is clinically manifest from birth. The presence of extra material from chromosome 18 affects the normal physiological development of the baby, with an impact on its health that will depend on how serious the chromosome abnormality is. Obviously, a total trisomy of chromosome 18 will be the most serious situation.
Treatment
Routine exams during the 18-20 weeks of pregnancy can show signs that your baby has Edwards syndrome.. When it is born, the unusually small placenta is one of the first signs that indicate the disorder.
What are the threadlike structures present in cells that help to keep genes intact?
Chromosomes are the threadlike structures present in cells that help to keep genes intact. These genes or genetic material usually carries the commands or instructions needed to make every part of a baby's body. During the formation of a zygote, when the egg and sperm join, 23 chromosomes from both the egg and sperm fuse to make a foetus which now has a total of 46 chromosomes . When either of the parents carries a wrong number of chromoso mal materials, the defect is passed on to the foetus, which now has a wrong number of chromosomes .
What does it mean when a baby has 3 copies of the chromosome 18?
A trisomy usually signifies that the baby chiefly has an extra chromosome in one or more body cells. In case of Trisomy 18 or Edward’s syndrome, the baby has 3 copies of the chromosome 18 which may ultimately lead to several abnormalities.
What is Edward's syndrome?
Edward’s Syndrome, termed medically as Trisomy 18 is a type of birth defect caused due to the presence of added genetic material i. e. a third copy of the chromosome 18 instead of the natural 2 copies.
What is the difference between partial trisomy and partial trisomy 18?
Partial Trisomy 18: In partial trisomy, the baby has only one part of the chromosome 18, i.e. the extra part of the chromosome 18 is attached to any other chromosome of the egg or sperm.
How many chromosomes are in a zygote?
During the formation of a zygote, when the egg and sperm join, 23 chromosomes from both the egg and sperm fuse to make a foetus which now has a total of 46 chromosomes.
