Dr. Tao Wang is an associate professor of pediatrics at the Johns Hopkins University School of Medicine. His areas of clinical expertise include global developmental delays and intellectual disability neurobehavioral disorders in children, and genetic and genomic syndromes and inborn errors of metabolism. 

Dr. Wang earned his M.D. from Zhongshan Medical University in China and a Ph.D. in human genetics from Johns Hopkins University. He completed his residency in pediatrics at Tufts -New England Medical Center Hospitals and performed fellowships in clinical genetics at Johns Hopkins University School of Medicine and clinical biochemical genetics at Kennedy Krieger Institute. 

His research interests include x-linked intellectual disabilities (XLID), autism spectrum disorders (ASDs) and inborn errors of metabolism of the central nervous system.

Dr. Wang is the associate director of the Medical Genetics Residency and Fellowship Program and a preceptor in the Predoctoral Training Program in Human Genetics.

Research Summary

Our lab studies the genetic and neuronal mechanisms underlying developmental brain disorders including intellectual disability (ID) and autism spectrum disorders (ASDs) and in developing effective treatment for these disorders.

To systematically identify novel disease-causing genes for X-linked ID (XLID), we use high-throughput genomic approaches including X-chromosome cDNA microarray and next-generation sequencing to screen all known genes and functional elements on human X chromosome in XLID patients. We study mechanisms of novel XLID genes using in vitro and neuronal assays, electrophysiology and mutant mouse models. Current projects are focused on characterizing novel XLID candidate genes involving glutamate-signaling pathway, and phosphorylation and palmitoylation of key neuronal proteins.

To understand mechanisms of synaptic dysfunction in ASDs, we sequence genes encoding all known synaptic proteins, synaptome, in patients to identify causal and risk variants. We conduct functional studies of these variants using in vitro and neuronal assays, electrophysiology and mutant mouse models. One current focus is to understand glutamate-signaling disturbance in social dysfunction in ASDs.

Patient Ratings & Comments

The Patient Rating score is an average of all responses to physician related questions on the national CG-CAHPS Medical Practice patient experience survey through Press Ganey. Responses are measured on a scale of 1 to 5, with 5 being the best score. Comments are also gathered from our CG-CAHPS Medical Practice Survey through Press Ganey and displayed in their entirety. Patients are de-identified for confidentiality and patient privacy.
