Biography

Professor Lam obtained his MBChB from The Chinese University of Hong Kong in 1991 and FRCPA in 1997 from The Royal College of Pathologists of Australasia with a double scope of practice in Chemical Pathology and Genetics. He obtained his PhD in 2000 from The Chinese University of Hong Kong. He obtained FRCP(Glas) from The Royal College of Physicians and Surgeons of Glasgow in 2012.


Professor Ching-Wan Lam is a chemical pathologist with 30 years experiences in inherited metabolic disease and has 200 publications on this subject. His research interests include various aspects of inherited metabolic diseases and genetic testing. For example, he identified the MECP2 gene, the first disease gene for non-syndromic infantile autism. The locus is called AUTSX3 (AUTISM, X-LINKED, SUSCEPTIBILITY TO, 3; MIM ID #300496). This work has been incorporated in the formulation of an international guideline for etiologic diagnosis of autism, i.e., The American College of Medical Genetics 2013 clinical practice guideline.


He identified the SMOOTHENED gene to be the driver gene in sporadic medulloblastomas. This work has provided important leads for development of SMOOTHENED inhibitors.  He also identified a new pharmacogenetic disease in which valproate, a first-line anti-epilepsy drug, can trigger onset of Mitochondrial Encephalomyopathy with Lactic Acidosis and Stroke-like episodes (MELAS). This work has led to a change in clinical practice that valproate is now contraindicated to patients with mitochondrial DNA disease. Professor Ching-Wan Lam is an Editor of Clinical Chimica Acta.
