Pua Chee Jian Edmund

BSc, BAppSc

National Heart Centre Singapore


Mr Edmund Pua graduated with a Bachelor of Biomedical Sciences majoring in Genetics at University of Adelaide and further studied at Queensland University of Technology to receive a Bachelor of Applied Science. 

At National Heart Research Institution Singapore (NHRIS), he study inherited cardiac conditions (ICCs) using next generation sequencing (NGS) approach. A comprehensive genetic test to diagnose all known ICCs including cardiomyopathies, familial hypercholesterolemia and prevent sudden cardiac death was developed in Year 2016 and being used by clinical and research laboratories worldwide. More recently, the team discovers the commonest caused of hypertrophic cardiomyopathy (HCM) in Chinese that improve the diagnostics yield of genetic test from 17.9% to 22.3% in Singaporeans. 

Additionally, his research counterparts also focus on the translatomics of cardiac diseases to reveal novel regulatory targets, translation patterns and mechanisms using small RNA (ribonucleic acid) sequencing, mRNA (messenger RNA) sequencing, ChIPSeq (chromatin immunoprecipitation sequencing) and ribosomal profiling and involved in bioinformatics supports for multiple research projects

With supports from National Medical Research Council and National Heart Centre Singapore, he has set up a HBRA:HTF (Human Biomedical Research Act: Human Tissue Framework) compliance biospecimen and DNA (deoxyribonucleic acid) core facility at NHRIS that stores thousands of blood samples, donated by patients with cardiac diseases and healthy volunteers.
