Summary

  • I am a trained clinical and biochemical geneticist with significant clinical management and clinical and translational research experiences in medical genetics. I have applied high-throughput sequencing (NGS, WES and/or WGS) and chromosomal microarray technologies as well as enzymatic tests in my research of rare neurodevelopmental disorders and disorders of pyruvate metabolism (DPM) such as pyruvate dehydrogenase complex deficiencies (PDCDs) as well as in the clinical arena for diagnosing rare and complex genetic disorders and other inborn errors of metabolism (IEM). My short-term goals include (1) application of high-throughput sequencing as a “hypothesis free” approach to identify the genetic etiology of complex metabolic conditions, such as primary- and secondary-PDCDs, urea cycle disorders (UCDs) and other mitochondrial disorders (MtDs), in order to improve diagnosis, management and design of future clinical trials of therapeutic interventions including small molecule and/or gene therapy for such disorders; (2) identification of biomarkers for implementation in newborn screening (NBS) for disorders associate with congenital lactic acidosis; (3) piloting a NBS protocol for early diagnosis of primary-specific PDCD newborns/infants for early intervention with ketogenic diet or other novel therapies; (4) use of high-throughput sequencing tools or molecular testing as 2nd tier test to optimize NBS for PDCD, glutaric acidemia type I and other metabolic disorders; (5) understanding the toxicity mechanism(s) of certain accumulating acyl-CoAs and other metabolites in the pathophysiology of specific organic acidemias (OAs) such as propionic and methylmalonic acidemias; and (6) understand specific disease-causing missense variants of PDHA1 and PDHB causing PDCD in the context of 3D E1 crystal structure, impacting structure and function, clinical phenotype, and novel therapies for PDCD.
