Dr. Brian Chung, one of the few clinical geneticists in Hong Kong, has established a clinical genetics program in 2010 with a strong research component. He provides clinical genetic services, such as genetic testing, in-patient and out-patient genetic evaluation and counselling, to patients with various genetic disorders. He conducts clinical studies on patients with various genetic disorders and he collaborates with linguists on discourse analysis research in cross-cultural genetic counseling.

Together with his research team, he has initiated array comparative genomic hybridization (aCGH) analysis in our department helping the diagnosing chromosomal abnormalities. 

His research focuses on the medical application of whole-genome and epigenetic technologies on the study of human diseases by identifying novel variants/genes as well as the epigenetic changes involved. With the NextSeq500 platform successfully installed and with the optimizing bioinformatics pipeline, his team aim at identifying novel mutations for rare disease using whole exome sequencing (WES).

Research

 

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:

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

 

Clinical Genetics & Genetic Counselling

 

l Disease burden, clinical manifestations & natural history of genetic syndromes
l 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:

l Whole genome DNA methylation studies in Chinese patients with SLE
l Childhood imprinting disorders
