Molecular Pathology

Supervisors:

Richard Press. MD, PhD

Location:

This rotation occurs at the OHSU DNA Diagnostic Lab, Marqam Plaza Building

Duration:

1 month

Goals & Objectives:

    Pathology resident education in molecular pathology stems from their required 1month rotation through the DNA Diagnostic Lab, a joint venture of the Pathology and Genetics departments. During this rotation the residents are exposed to the unique language, technology, and predictive interpretive aspects of molecular pathology through a combination of didactic lectures, teaching conferences, independent study, clinical-pathologic presentations, and hands-on lab experience. The interpretive reports and consultative activities that the resident will participate in include the clinical interpretation of any of the DNA lab tests listed below. DNA-based lab tests are not a significant part of any other Pathology resident rotation.

Graduated Responsibility, Supervision and Evaluation:

1.    Consultation with clinical staff on proper utilization and interpretation of molecular diagnostic
        tests.

2.    Consultation with laboratory staff on the clinical/pathological correlates of the various disease
       entities being evaluated.

3.    Acquiring and disseminating clinical and familial information on the patients being evaluated in the        lab.

4.    Regular reviews of the primary laboratory data for interpretation, oral presentation to the
       laboratory director, and write-up of an interpretive report.

5.    The privilege of consulting with the clinical staff on proper utilization and interpretation of
       molecular diagnostic tests will be granted to the resident by the laboratory director, once
       he/she has demonstrated sufficient proficiency in the field. The other privileges listed above
       will be immediately granted.

OHSU has recently been accredited for a new "molecular genetic pathology" fellowship program (1 year in duration) in which an MGP fellow will spend at least 3 months in the DNA Diagnostic lab, in addition to rotations through Cytogenetics, Biochemical Genetics, and the pursuit of independent research.
