Clinical Genetics Training Program

About our clinical and laboratory genetics training programs

Our genetics training programs integrate clinical and research experiences at both Children's Hospital of Philadelphia (CHOP) and the Hospital of the University of Pennsylvania. Clinical training programs include an integrated Pediatric/Genetics Residency program and a Medical Genetics Residency training program for physicians who have completed training in a clinical specialty such as pediatrics, internal medicine, obstetrics-gynecology, or other relevant specialties, as well as the Medical Biochemical Genetics Fellowship program. Laboratory training programs include the Laboratory and Genomic Diagnostic Fellowship program and Clinical Biochemical Genetics Fellowship program

Clinical training programs

Pediatrics/Genetics Combined Residency Program

We offer a four-year integrated Pediatrics/Genetics Residency program (in conjunction with the Department of Genetics at the University of Pennsylvania School of Medicine) leading to board eligibility in both disciplines. The first year of the training program is a typical pediatrics intern year. The remainder of the years integrate pediatrics and medical genetics rotations. Please see below for a listing of Medical Genetics rotations.

Medical Genetics Residency Program

The University of Pennsylvania and Children's Hospital of Philadelphia (CHOP) offer a unique opportunity for training in human genetics. The program integrates experiences at CHOP, the Hospital of the University of Pennsylvania (HUP), and other clinical and research opportunities available at the University of Pennsylvania.

This training program, which is under the co-sponsorship of the Departments of Pediatrics, Genetics, Medicine, and Obstetrics and Gynecology at the University of Pennsylvania and the Division of Human Genetics and Molecular Biology at CHOP, is designed for physicians who have completed training in a clinical specialty such as pediatrics, internal medicine, obstetrics-gynecology, or other relevant specialties.

For the MD trainee, the first year is devoted to training in clinical genetics. Although the schedule is individualized according to a person's prior experiences, interests and training, the usual rotations include:

  • Clinical genetics service
  • Biochemical genetics service, including experience in metabolic screening
  • Laboratory rotation (cytogenetics, biochemical genetics, molecular genetics)
  • Adult medical genetics at HUP
  • Prenatal Genetics at HUP

During the second year of the training, residents focus on research activities and continue to participate in genetic clinics. At the end of the training, the resident should be competent to diagnose, clinically manage, and counsel patients with chromosomal anomalies, inborn errors of metabolism, adult genetic conditions, and other genetic syndromes. Residents should have a thorough understanding of the use and interpretation of genetic and metabolic laboratory tests that are essential to pre- and post-natal diagnosis and management.

The graduate will be eligible to take the American Board of Medical Genetics examinations in the relevant disciplines and should qualify for faculty appointment in an appropriate department in a major medical school. Foreign medical graduates must have at least two years residency training in an accredited program in the United States. USMLE exams 1, 2 and 3 must be completed and scores forwarded with your application for all applicants.

Clinical services

Educational experiences

Clinical and laboratory trainees have a variety of educational experiences:

  • Weekly Genetics Grand Rounds
  • Weekly didactic lectures, taught by faculty in the division
  • Occasional opportunities to teach other trainees
  • Didactic experiences within various rotations (see above)

Presentation and meeting opportunities

Trainees have opportunities to give presentations and attend meetings:

  • Case presentations at Genetics Grand Rounds.
  • Clinical trainees attend NAMA (North American Metabolic Academy) once during their training.
  • Clinical trainees are expected to attend at least one meeting during their final year of training:
    • David W Smith Dysmorphology meeting
    • American College of Medical Genetics meeting
    • American Society of Human Genetics meeting
    • Society of Inherited Metabolic Disease

Research program

Combined Pediatrics/Genetics trainees spend roughly 75 percent of their final year of training devoted to research. Medical Genetics trainees spend 75 percent of the second and third years of training devoted to research. The trainee may choose from many research opportunities in the following areas: molecular genetics, cytogenetics, somatic cell genetics, cancer genetics population genetics, biochemical genetics, gene regulation, prenatal diagnosis, teratology, embryology, differentiation and developmental genetics, and immunogenetics. Trainees are expected to complete a major research project as the primary investigator. The opportunity to participate in an additional (fourth year) highly specialized research project may also be available.

How to apply

Clinical training programs

CHOP participates in the National Resident Matching Program (NRMP) for the Medical Genetics and Pediatric/Genetics combined residencies. Applicants should submit their applications through ERAS. Please visit CHOP’s Pediatrics Residency Program page for details about how to apply using the ERAS system.

Other requirements

To carry out its mission, it is of critical importance for the Children’s Hospital of Philadelphia (CHOP) to keep our patients, families and workforce safe and healthy and to support the health of our global community. In keeping with this, CHOP has mandated all workforce members (including trainees) on site at any CHOP location for any portion of their time be vaccinated for COVID-19 as a condition of employment.

This mandate also applies to workforce members or trainees performing work for CHOP at non-CHOP locations. Additionally, all workforce members based in or regularly scheduled to work at any New Jersey location are mandated to be both vaccinated and boosted for COVID-19, with booster timing consistent with applicable guidelines. The CHOP COVID-19 vaccine mandate is in alignment with applicable local, state and federal mandates. CHOP also requires all workforce members and trainees who work in patient care buildings or who provide patient care to receive an annual influenza vaccine. Employees may request exemption consideration for CHOP vaccine requirements for valid religious and medical reasons. Please note start dates may be delayed until candidates are fully immunized or valid exemption requests are reviewed. In addition, candidates other than those in positions with regularly scheduled hours in New Jersey, must attest to not using tobacco products.

Children's Hospital of Philadelphia is an equal opportunity employer. We do not discriminate on the basis of race, color, gender, gender identity, sexual orientation, age, religion, national or ethnic origin, disability, protected veteran status or any other protected category. CHOP is a VEVRAA Federal Contractor seeking priority referrals for protected veterans.
