Fast Facts on Genetic Disorders and PGD
According to the March of Dimes:
-
1 out of every 100 Americans is born
with a serious genetic defect.
-
Approximately 20,994 California babies
are born with a birth defect annually.
-
There are more than 4,000 known birth
defects.
-
Birth defects are the leading cause of
death in the first year of life and account for more than 1 in 5
infant deaths.
-
For babies born with birth defects in
1992, estimated lifetime costs total 48 billion.
-
According to the National Center for
Health Statistics, in 1995, 11.6% or 453,722 babies were born to
women over 35.
From the book Planning Your Pregnancy
and Birth by the American College of Obstetrics and Gynecologists:
-
All human cells have 46 chromosomes each
possessing between 50 million and 250 million base pairs of DNA
molecules in each chromosome.
-
A gene is a segment of DNA that is coded
to pass along a certain trait.
-
The body has about 50,000 to 100,000
genes.
-
There is a 1 in 4 chance of passing a
genetic disorder on to the child if both partners carry the same
recessive disorder. A 1 in 2 chance if either carries a dominant
disorder.

Facts from the American Society of
Reproductive Medicine:
-
About 7% of still births and neonatal
deaths have chromosomal abnormalities.
-
Recurrent miscarriages may be due to
genetic abnormalities.
-
Preimplantation Genetic Diagnosis - PGD
was first performed in 1989.

Nearly 200 babies have been born
following the first PGD.
-
Over 200 disorders could potentially be
prevented by using PGD to screen gender based disorders.
