Molecular Genetics Pathology Fellowship Program

Molecular Genetics Fellowship


The ACGME accredited Molecular Genetics Pathology Fellowship at Cedars-Sinai offers comprehensive training in all areas of molecular pathology including in-depth exposure and experience in molecular test strategies, decisions on application of testing, test interpretation and communication with other physicians and patients regarding test results. Fellows may come from a background in pathology or internal medicine, and on completion of the fellowship are competent to perform as junior staff in either a community or academic setting. The Cedars-Sinai Molecular Genetics Pathology fellowship is highly competitive. Therefore, interested applicants with a pathology background should strongly consider concurrent application for the Surgical Pathology Fellowship, as qualified candidates may be offered Surgical and Subspecialty Fellowship positions in consecutive years. The Medical Center has many sources of excellent adult and pediatric cases and material, including the Medical Genetics Institute, the Samuel Oschin Comprehensive Cancer Center and a busy hematopathology laboratory service.

The program is provides experience in the practice and administration of molecular genetics pathology including learning how to select, apply and interpret molecular studies and create cogent and integrative reports in a variety of areas including hematopathology, infectious diseases, solid tumors, inherited diseases, pharmacogenopmics, genetics, cytogenetics, and biomedical genetics, and in the HLA Laboratory. In addition, molecular genetics pathology fellows who are pathologists will spend one month in the Medical Genetics Clinical rotation, while those boarded by the ACMG will spend this time in Anatomic Pathology.



Program Structure

The program is structured to provide all needed core training over a one-year period and to assure that learning of the techniques and skills needed for excellence of practice in and administration of molecular genetics pathology (MGP) is accomplished in a coordinated fashion. The MGP fellow participates in learning how to select, apply and interpret molecular studies and create cogent and integrative reports in a variety of areas including hematopathology, infectious diseases, solid tumors, inherited diseases, pharmacogenomics, genetics, cytogenetics, and biomedical genetics, and in the HLA laboratory. In addition, MGP fellows who are pathologists will spend one month in the Medical Genetics Clinical rotation, while those boarded by the ACMG will spend this time in Anatomic Pathology. An overview of rotation specifics is provided below.

Molecular Hematopathology provides a background to the non-random mutations and gene rearrangements associated with leukemias and lymphomas. The MGP fellow will become familiar with the technologies used to perform the molecular tests (quantitative PCR etc.) as well as gain experience in running the test and trouble-shooting in the lab.

Molecular-Infectious Disease provides experience with numerous molecular technologies used in the identification of viruses, bacteria, and other microorganisms. The fellow also learns how to identify and investigate and control nosocomial infections in the hospital in collaboration with the infectious disease department and epidemiology. The MGP fellow will become familiar with repetitive PCR sequence analysis as part of the epidemiologic work-up.

In Molecular-Solid Tumors, the fellow reviews the morphologic evaluation of solid tumors and the non-molecular testing used to classify these specimens, and becomes familiar with the non-random mutations and gene rearrangements that occur in different classes of solid tumors, and their use in diagnosis and prognosis. The fellow is involved in the development and implementation of new tests based on knowledge of the current scientific literature. In the future, expression micorarrays may become part of the testing menu.

In the inherited disease rotation, the fellow learns to recognize clinical, inherited disorders and to evaluate a family history. The fellow will work with researchers in the institution to help translate findings in the research lab into clinical tests for rare disorders followed at our institution and identified in specific, local ethnic populations. The fellow will become familiar with the concepts of genetic heterogeneity and variable expressivity and be able to use their understanding of these phenomenon to individualize testing for particular families. It is planned by the department to introduce Comparative Genomic Hybridization arrays and have the MGP fellow participate in their validation and implementation for CLL, AML, and other hematopoietic malignancies.

The new field of pharmacogenomics will give the fellow the opportunity to be at the forefront of individualized medicine by learning to use genetic information about drug activation and metabolism to help predict the appropriate dose of a drug. They will learn about drug metabolism, the various enzyme pathways involved and the genetic variation in these pathways that exist in different populations and families. The fellows will be involved in the development of new tests related to drug selection and dosing, and be involved in the process of educating community physicians about the value of this approach.

In cytogenetics and molecular cytogenetics the fellow learns different methods of cell culture, banding and karyotyping and molecular cytogenetic (FISH) techniques. The fellow is involved in the writing reports and interpretation of results for prenatal diagnosis, evaluation of congenital abnormalities and reproductive problems, as well as cancer cytogenetics.

The HLA laboratory allows the fellow to learn methods and relative merits of serological and molecular typing using the variety of methodologies available in they lab for matching donors and recipients experiencing transplantation of bone marrow, liver, kidney, heart, lung, pancreas and other tissues.

In the anatomic pathology and autopsy services, the fellow becomes familiar with autopsies of dysmorphic fetuses and still born infants or others with identified genetic disorders, malformations, and other inherited disorders and learns to identify anatomic features that are associated with genetic diseases. In addition, the department of pathology offers subspecialized surgical pathology, and the fellow will have the opportunity to choose an area of interest in which to develop a translational research project.

In the medical genetics clinical rotation, the fellow sees a wide variety of pediatric and adult patients with inherited disorders in conjunction with the genetics residents and faculty. The Cedars-Sinai medical genetics institute has an international reputation for skeletal dysplasia, as well as dysmorphology, prenatal diagnosis, metabolic and adult onset disorder clinics. The MGP fellow will be involved in non-directive genetic counseling with patients from a wide variety of socio-economic and ethnic backgrounds.

In the biochemical genetics laboratory rotation, the fellow is exposed to the primarily protein-based methodologies used to test for different inherited enzyme and metabolic deficiencies, and discuss them with their attending. The focus will be on understanding the relative merits of biochemical versus molecular testing for genetic disease.
