Genetic Screening and the Adult Adoptee
There are medical issues that go with each child's family history, and not all family members may be forthcoming and honest when telling case-workers their stories in an adoption agency. People can be funny that way.
To get a sense of how genetic diagnosing affects parents, consider the following from:
GENETIC SCREENING AND ETHICS AN OVERVIEW By: David Devore

TABLE 1
GENETIC DIAGNOSIS
I. Genetic diagnosis is currently available for the following:
- sex
- abnormal chromosome number
- early onset conditions (e.g. sickle cell, cystic fibrosis)
- late onset conditions (e.g. Huntington disease, polycystic kidney disease)
- susceptibility to (e.g. hypercholesterol, alcoholism)
- carriers of recessive genes (e.g. sickle cell, cystic fibrosis)
II. Inherited conditions in which DNA markers have been found:
|
|
III. Inherited disorders in which disease gene locus has been identified:

PREVALENCE OF SOME GENETIC DISEASES
Estimates of the number of Americans having diseases with a genetic cause or an important genetic component
Disease | Incidence | Nature of Illness |
---|---|---|
polycystic kidney disease | 400,000 | kidney damage, failure |
Down's syndrome | 250,000 | range of mental retardation |
Sickle-cell anemia | 50,000 | impaired circulation, anemia |
Cystic fibrosis | 30,000 | chronic respiratory and digestive problems |
Huntington's disease | 25,000 | progressive mental and neurological degeneration |
Duchenne muscular dystrophy | 30,000 | muscle degeneration |
Hemophilia | 20,000 | uncontrolled bleeding |
Phenylketonuria | 10,000 | mental deficiency |
Alzhemier's disease | 2-4 million | mental degeneration |

"Individual states in the United States finance their newborn screening programs in different ways. Most states collect a fee for screening, which ranges from less than $15 to nearly $60 per newborn. Health insurance or other programs can pay this fee for the newborn's parents." http://learn.genetics.utah.edu/units/disorders/newborn/
But what about the adoptee who has no basic or correct medical history information?
My question is, in who's best health interest is genetic testing?
