  • Explain the mechanisms of nucleic acid target amplification and nucleic acid signal amplification. List examples of each technique in the molecular diagnosis of hematopathology, infectious disease, and solid tumor specimens.
  • Explain the principles of the polymerase chain reaction (PCR) and diagram the steps in the PCR reaction, and now common inhibitors of downstream applications (especially PCR)
  • List and describe applications of PCR (including reverse-transcription PCR, multiplex PCR, qualitative and real-time PCR, allele-specific PCR, single base pair extension) in hematopathology, solid tumor and infectious diseases.
  • Describe the following methods for nucleic acid detection and how to evaluate quality of extracted nucleic acid or amplified DNA products: gel electrophoresis, blotting, hybridization, and fragment analysis. List examples of each technique in the molecular diagnosis of hematopathology, infectious disease, and solid tumor.
  • Explain how the nucleotide sequence of DNA is determined and list applications of DNA sequencing to molecular diagnosis.
  • Understand how human identity testing using highly polymorphic short tandem repeats (STR) in the human genome is applied to the analysis of bone marrow engraftment.
  • Understand molecular classifications of leukemia and lymphoma and appropriate method for testing
  • Understand qualitative/quantitative methods for CML and JAK2 testing in MPN
  • Understands principles and techniques associated with direct mutation detection:
    • Restriction fragment length polymorphism
    • FRET analysis
    • Single base extension
    • Allele specific amplification
    • Repeat primed PCR
    • Methylation specific PCR

  • Know and understand the principles and techniques of Sanger Sequencing
  • Recognize and analyze common chromatograph patterns, such as heterozygous bases and insertions and deletions
  • Describe the approximate analytic sensitivity for mutation detection
  • Know the pitfalls related to PCR that can lead to false negative results 

Practice Based Learning and Improvement

  • Understand the use of quality assurance and control in the molecular laboratory.
  • Explain 'unidirectional flow' with regards to contamination prevention and effective strategies for contamination prevention, with respect to the appropriate design and workflow in molecular laboratories to ensure quality and reduce the risk of carry-over contamination
  • Quantitate purified nucleic acid samples by UV spectrophotometry and is able to use the parameters to determine the quality of extracted nucleic acids.
  • Analyze and interpret molecular diagnostic data for inherited diseases, hematopathology, infectious disease, and solid tumor specimens; including appropriate reporting and medical significance of positive and negative test results.
  • Perform a literature search on an assigned clinical test and give presentation to the MG faculty and staff.

Professionalism

  • Convey information to laboratory staff in a timely manner
  • Reading independently on topics related to patient case material and search primary sources
  • Demonstrate self-motivation and organization in pursuit of rotation requirements (reading and clinical service time)
  • Demonstrate a commitment to ethical principles pertaining to (1) patient privacy and autonomy, (2) the provision or withholding of test results, (3) confidentiality of patient information, (4) informed consent, (5) conflict of interest, and (6) business practices that are in conflict with stated principles of professionalism.
  • Demonstrate courteous and collegial behavior with laboratory staff (laboratory supervisor will evaluate resident based on input from laboratory personnel)

Interpersonal and Communication Skills

  • To effectively communicate with clinicians about the test results with appropriate interpretation.
  • To effectively communicate with lab staff about appropriate sample identification and selection, issues regarding test result interpretation and troubleshooting

Systems-Based Practice

  • Understand concepts of laboratory design and procedure that are specific to nucleic acid testing.
  • Understand primary issues of QA/QC in molecular amplification, including common sources of false positive and negative results, and basic trouble-shooting
  • Explain the regulatory requirements governing all molecular tests, including laboratory developed tests, and compare the differences and similarities among them.

  • Describe the validation process for a lab developed test and requirements for lot validation for all test types.
  • Contrast verification of an IVD with validation of an LDT
  • Explain the important legal, ethical, and social implications with regards to larger scale/genomic testing and the ability to 'blind' analytes to prevent unintended data analysis (i.e. NGS for tumor discovering AD condition)

Duration

The rotation in molecular genetics is two weeks long and typically occurs during year 2.

Duties and Responsibilities of Residents

  • Because the core curriculum is taught at one point in the Resident's training, responsibilities do not change on a yearly basis.
  • Review and sign out all results with the Attending Pathologist.
  • Review molecular laboratory procedures.
  • Participate in division case conference, molecular laboratory regular or QA meeting and clinical pathology QA meeting.
  • Present a topic to laboratory faculty and staff.

Teaching Staff

  • Thomas Prior, PhD – Rotation Director
  • James Metcalf – Supervisor, Molecular Genetics laboratory

Supervision and Evaluation

Residents meet on a regular basis with the Attending Pathologist and with the lead technologists for supervision. Residents are evaluated on a monthly basis with regard to acquisition of the Core Competencies listed in this Program Statement. Evaluations are forwarded to the Residency Program Director, where they are available for review. Direct observation and feedback. In addition, residents will take pre- and post-rotation examination.
