Department of Molecular and Human Genetics

Clinical Biochemical Genetics Fellowship


Trainees in Clinical Biochemical Genetics spend three months learning each of the following methods: tandem mass spectrometry; gas chromatography/mass spectrometry; high-pressure liquid chromatography (amino acid analysis) and enzyme analysis in the Biochemical Genetics Laboratory.

Each day, the trainee participates in writing interpretations for all tests with one of the laboratory directors. The remainder of the training is spent developing new diagnostic tests or methodologies for the laboratory or working on a research project.

The Biochemical Genetics Laboratory was established more than 25 years ago and has been a leader in the diagnosis of inborn errors of metabolism. The laboratory analyzes over 8,000 clinical samples per year as well as providing contract service for research. In addition to standard biochemical genetics testing, the laboratory was the first laboratory in the United States to offer large scale metabolomics profiling to screen for inborn errors of metabolism.

Laboratory Director: Sarah Elsea, Ph.D.
Medical Director: V. Reid Sutton, M.D.
