Summary
Genetic service programs provided counseling to over 130,000 individuals and detected 436 fetal abnormalities via amniocentesis. Metabolic screening identified numerous cases of phenylketonuria and hypothyroidism.
Area of Science:
- Medical Genetics
- Public Health
- Genomic Medicine
Background:
- Funded by the National Genetic Diseases Act, 34 state genetic service programs operated in the US during FY 1979-1980.
- These programs aimed to provide genetic counseling and diagnostic services to at-risk populations.
Purpose of the Study:
- To report on the utilization and outcomes of genetic services provided nationwide.
- To document the effectiveness of genetic counseling, amniocentesis, and metabolic screening programs.
Main Methods:
- Analysis of data from 34 state genetic service programs funded by the Health Services Administration.
- Review of genetic counseling, amniotic fluid analyses, and newborn screening for metabolic disorders.
Main Results:
- Over 131,818 individuals received genetic counseling, and 42,003 amniotic fluid analyses detected 436 abnormal fetuses (1%).
- Amniocentesis utilization for advanced maternal age varied widely (5%-49%).
- Metabolic screening of over 3 million specimens identified 195 cases of phenylketonuria and 536 of hypothyroidism, among other rare disorders.
Conclusions:
- State-funded genetic programs effectively provided essential services, including genetic counseling and diagnostic testing.
- Newborn screening identified significant numbers of infants with treatable genetic conditions, highlighting the importance of these public health initiatives.
