Researchers in Singapore tested a new nationwide program to offer couples genetic screening. The program uses a test that looks for changes in 112 genes linked to recessive diseases, which a child only inherits if both parents carry a change in the same gene. The program included online education and counseling tailored for Singapore's diverse population.
In this early pilot phase, over 1,600 couples registered interest, and 456 couples received their results. Of those, 4 couples (0.9%) were found to be at increased risk of having a child with one of the screened conditions. A community survey showed 59% of people were interested in the program, but interest varied among different groups.
The study also found that healthcare professionals expect this kind of screening to become more common, but many feel they need more training and resources to discuss it confidently. Religious leaders surveyed indicated support for the program.
It is important to know this report describes the first steps of starting a new health program. The results show initial interest and early findings, but they are not from a long-term study that compares outcomes. The program is still being developed to make it accessible to everyone and to better support doctors and patients.
