Designer Babies: A Brief Overview By Gillian S
The Techniques • The current techinques involved in creating designer babies are Preimplantation Genetic Diagnosis and Preimplantation Haplotyping
Preimplantation Genetic Diagnosis • Used for sexing and the identification of diseased embryos through biopsies. • Involves such techniques as Polymerase Chain Reaction and FISH. • Can produce false negatives or false positives often to the severe detriment of the family.
FISH • Also known as fluorescent in situ hybridization • A cytogenic technique • Used for sexing • Tracks genetically and sex-linked disorders. • Chromosomal abnormalities • Not very accurate often detects inflated numbers of abnormalities due to normal development
Polymerase Chain Reaction • Involves the creation of more DNA to make available for testing • Problem: Minute amount of genetic material available for testing • Sensitive to contamination
Preimplantation Genetic Haplotyping • More reliable and advanced than PGD • Uses DNA fingerprinting rather than a genetic signature • Allows for more tests, has a higher success rate, and increased reliability.
Ethics • Cases where people use PGD and PGH to solve cosmetic disorders. • Donor Siblings • Family Planning
Cosmetic Disorders • Cure squint - a non-lethal trait. Bastardization of PGD and PGH’s original purpose which was to determine sex and to prevent the inheritance of lethal conditions
Donor Siblings • Case in which a family had a terminally ill son so they created a child with the same cord blood as him in an attempt to cure him • Other child could also have disease, could die • Where does society need to stop and simply let go of their children so they can die?
Family Planning • Sons are more desired • Skewing of the gender ratio • Create Social Unrest • Should not be allowed simply to “balance the family”
The Answer • Processes need to be refined to efficaciously create techniques that would eliminate lethal disorders • Designing children that do not have the potential to inherit a life threatening disorder is decidedly unethical and will simply result in social unrest.
