Research Scope


An overview of research focus

Our research focus on understanding the genetic etiology of undiagnosed genetic disorders, including neurodevelopmental disorders, birth defects. Applying state-of-art techniques we aim to discover the novel disease-causing genes, investigate the genotype and phenotype of the human diseases and traits which would provide patients a better and personalized treatment.


A list of research topics

  • Undiagnosed genetics disorders

  • Neuro-metabolic genetics

  • Inborn errors of metabolism disorders

  • Genomic identification and functional characterization of disease-causing genes

  • Constitutional mosaicism in the human diseases and traits
