The laboratory genetics and genomics fellowship is a two-year program for individuals with prior clinical or research experience designed to train fellows to have excellent interpretive skills and consultative and managerial abilities required to direct the operations of a clinical cytogenetic, cytogenomic or molecular diagnostic laboratory.


The laboratory genetics and genomics (LGG) fellowship was accredited by the American Board of Medical Genetics and Genomics on December 15, 2017.  The LGG fellowship has combined the elements of the previous clinical cytogenetics and clinical molecular genetics fellowships into one new fellowship in laboratory genetics and genomics.


Primary educational objectives include:

  • Obtaining broad knowledge in medical genetics and human cytogenetics, cytogenomics and molecular genomics, including prenatal and postnatal cytogenetic and molecular diagnosis, infertility and pregnancy loss, somatic cancer and hematopathology genetic testing
  • Acquiring diagnostic and interpretive experience across a wide range of disorders
  • Obtaining technical expertise and knowledge in quality control and quality assurance procedures, in constructing quality improvement plans, and CAP/CLIA/state/federal specific regulatory requirement
  • Gaining the ability to understand the stringent requirements needed to introduce new laboratory tests and to appreciate rigid validation standards that include a thorough evaluation of methodology and clinical utility
  • Acquiring working knowledge of modern genetic testing platforms and procedures as well as the knowledge of bioinformatics and its use in genomics analysis
  • Developing an understanding of the heterogeneity, variability and natural history of genetic and genomic disorders
  • Developing the ability to communicate laboratory results accurately and with ethical and medical standards, in the capacity of consultant to medical genetics professionals, to other clinicians and directly to patients in concert with other professional staff.

Investigative research, either clinical or basic, is required during the fellowship. Emphasis is placed on application of the scientific method, preparation of written reports on findings, presentation of research data and gaining experience in current genetic diagnostic techniques. Trainees are expected to present their research at national meetings and publish original papers in peer-reviewed journals.

Didactic training is provided by formal lectures, case conferences, seminars and journal reviews. Additionally, Washington University graduate school courses may be required, depending upon previous training and experience.


Training is held in the state-of-the-art Cortex building on the edge of the medical campus known as the CORTEX District (Center of Research, Technology and Entrepreneurial Exchange).


The application for the 2023-2025 fellowship position is now open. Please apply through our online application system
We will start the application review process in the summer.
