Summary
A Tay-Sachs Disease (TSD) screening program for Jewish high school students achieved 67% participation. Education improved knowledge, but blood sampling was a barrier, suggesting cheek swabs for future genetic testing.
Area of Science:
- Medical Genetics
- Public Health
- Neurodegenerative Disorders
Background:
- Tay-Sachs Disease (TSD) is an autosomal recessive neurodegenerative disorder.
- TSD disproportionately affects the Ashkenazi Jewish population, necessitating targeted screening.
- Community-based genetic screening programs are crucial for managing hereditary diseases.
Purpose of the Study:
- To evaluate the effectiveness of a Tay-Sachs Disease carrier screening program for high school students.
- To assess participation rates, knowledge acquisition, and attitudes towards genetic testing.
- To identify barriers to participation and provide recommendations for future programs.
Main Methods:
- Implementation of an educational, counseling, and carrier testing program for 15-18 year olds.
- Analysis of participation rates, knowledge levels, and student feelings/attitudes.
- Identification of impediments to test uptake.
Main Results:
- Seven hundred and ten students participated, with a 67% testing uptake.
- A carrier rate of 1 in 28 was identified within the screened population.
- High levels of knowledge were achieved, with feelings and attitudes significantly influencing decision-making.
Conclusions:
- The screening program demonstrated high student knowledge and engagement.
- Blood sampling posed a significant barrier to test uptake.
- Recommends using DNA analysis on cheek brush samples to improve accessibility in future Tay-Sachs Disease screening programs.
