Research Interests

Medical application of whole-genome technologies
Using cutting-edge technologies including CNV arrays, whole exome/genome sequencing and detailed phenotypic evaluation, we identify novel variants/genes involved in the pathogenesis of human diseases. Current projects include

    • Genetic Diagnosis of RASopathies using Next Generation Sequencing.
    • Exome/whole genome sequencing of patients with congenital heart disease/neurodevelopmental disorders.
    • whole exome sequencing of families with rare genetic syndromes

Clinical Genetics & Genetic Counselling

    • Disease burden, clinical manifestations & natural history of genetic syndromes
    • Communication/discourse analysis in genetic counseling in different clinical settings including inherited arrhythmia clinics, prenatal diagnosis, preimplantation genetic diagnosis (in collaboration with Dr Olga Zayts, Dept of English, HKU)

Epigenetics and Human Disease

    Epigenetics is the study of heritable changes in gene expression or cellular phenotype caused by mechanisms other than changes in the underlying DNA sequence and it includes DNA methylation, chromatin remodeling, RNAi and prions/structural inheritance systems. Using various technologies including bisulphite-converted DNA pyrosequencing, MLPA and whole genome DNA methylation arrays, we study various common and rare disorders in which epigenetics and imprinting is implicated in the pathogenesis. Current projects include:
    • Whole genome DNA methylation studies in Chinese patients with SLE
    • Childhood imprinting disorders
