A carrier screening programme for common genetic autosomal recessive diseases is described. The programme focuses on testing of adolescents in their last year of high school. The main purpose of this programme is to educate the population in high-risk communities, to offer carrier screening of autosomal recessive diseases (Tay–Sachs and β-thalassaemia diseases) and to provide counselling about reproductive options. The specific age range targeted allows for education and screening to occur before reproduction. This is a unique programme that was developed in conjunction with the community. Although there remains controversy regarding the screening of adolescents in other areas of the world, this programme is well accepted and has continued to flourish in our specific community for over 30 years.

Key concepts:

  • Genetic carrier screening programmes need education, effective counselling and support from the community to be successful.

  • Genetic screening of adolescents in our community is well accepted by the targeted populations.

  • Adolescents who obtain information through carrier testing understand their risks and later utilize this information when they consider their reproductive options.
