Building a National Precision Medicine (NPM) programme – SG10K_Health
The SG10K_Health project is a multi-institutional initiative developing an ‘all-of-Singapore' coordinated approach to precision medicine (PM). PM is a fast emerging field that seeks to improve treatment and prevent disease by considering individual and population genetic variation in genes, environment and lifestyle patterns. Through PM, patients may receive more accurate diagnosis, customised treatments achieving maximal benefit while minimising side effects, and reduced health care costs by avoiding ineffective treatments. At present, the Asian population is severely under-represented in the public genotypic databases. The current lack of large-scale control databases of Asian-specific genetic variation linked to clinical phenotypes is a significant barrier to the conduct of PM in Asia, to avoid mis-diagnosis and overtreatment due to the mistaken identification of pathogenic variants. The Singaporean population consists of three major ethnic groups, Chinese, Malay, and Indian, which together represent over 80% of the genetic variation in Asia. The presence of these three major ethnic groups in a single country thus offers a unique opportunity for Singapore, despite its small size, to contribute to global efforts in PM, complementing other large-scale efforts such as All of US and Genomics England.
The SG10K_Health project aims to empower biomedical and genetic studies of Singapore and Asian-centric diseases by: 1) building local infrastructure and deep capabilities to generate, analyse and store human genetic data at population scale, in a safe, secure and rapid manner, 2) generating a diverse and rich control dataset of Asian populations for genetic association study of diseases, and 3) developing advanced analytical tools for genetic variants interpretation to derive disease risk predictions and identify clinically actionable variants. Notably, statistical estimates indicate that a genomic data set of 10,000 individuals will be sufficient to capture essentially all common alleles (ie more than 1% allele frequency) in our Singapore population.
Our collaborative academic partners include representatives from four A*STAR Research Institutes (BII, I2R, IHPC and SICS), three local medical schools (SingHealth Duke-NUS, Lee Kong Chian School of Medicine - NTU and Saw Swee Hock School of Public Health - NUS), Singapore Eye Research Institute (SERI), Tan Tock Seng Hospital (TTSH) and the National Supercomputing Centre (NSCC).
Professor Patrick Tan, Executive Director at GIS, Director at SingHealth Duke-NUS Institute of Precision Medicine (PRISM), and Professor at Duke-NUS Medical School, said,
“The project provides a pilot genetic map of Asian populations that allows us to measure precisely the genetic contribution to disease, and combine it with other sources of data within a data-driven healthcare system. Potentially, this will provide insights to prevent disease before it occurs, diagnose disease earlier, and ensure that therapies are deployed in a way that maximises clinical benefits while minimising adverse effects. This will benefit both Singapore and the Asian population at large by providing more effective and efficient healthcare services.”
