The Complete Guide to American Board of Medical Genetics and Genomics (ABMGG) Laboratory Genetics and Genomics (LGG) Fellowship

If you're a doctoral candidate in genetics or a post-doctoral research fellow in the field, you might be considering the next steps in your career to transition from basic science research to clinical genetics. If this sounds like the path you're exploring, the American Board of Medical Genetics and Genomics (ABMGG) Laboratory Genetics and Genomics (LGG) Fellowship might be on your radar. But what exactly is this fellowship, and how can it shape your career in the fascinating world of genetics? Let's delve into the details.
Question #1: What Is a clinical lab geneticist?
A clinical lab geneticist is a specialized medical professional with expertise in interpreting and diagnosing genetic disorders through laboratory testing. These experts bridge the gap between molecular biology and patient care, playing a crucial role in the healthcare system.
In their role, clinical lab geneticists perform genetic testing and sign out the final genetic test report. They analyze genetic data, interpret test results, and provide comprehensive insights based on an individual's genetic information. This involves the diagnosis of inherited disorders or cancers, identification of potential health implications, and guidance on personalized patient care strategies.
Additionally, clinical lab geneticists navigate the cutting-edge technologies driving genetic testing. Using cutting-edge technologies, they develop new genetic testing from molecular genetic testing to cytogenetic testing, and ensure the accuracy and reliability of results, maintaining the highest standards in laboratory practices.
Collaboration is a cornerstone of their work. Clinical lab geneticists actively work with other healthcare professionals, including clinical geneticists, oncologists, pathologists, and genetic counselors. Their contributions to comprehensive patient care involve interpreting genetic test results in the context of a patient's medical history, and based on this result, clinicians can provide genetic counseling, and offers guidance on preventive measures and treatment options.
In terms of qualifications, clinical lab geneticists are typically clinical genetics lab directors with ABMGG board certification. They hold a doctoral degree (MD and/or PhD) in genetics and have completed a clinical fellowship program, such as ABMGG LGG fellowship (for PhD geneticists) or ABP MGP fellowship (for MD pathologists).
Question #2: What is the ABMGG LGG fellowship?
The Program Overview:
The ABMGG (American Board of Medical Genetics and Genomics) LGG (Laboratory Genetics and Genomics) Fellowship is a specialized training program designed for individuals with a doctoral degree in genetics. Typically accredited by the ACGME, it serves as a pivotal step in the career pathway for those aspiring to become clinical laboratory geneticists. Successful completion of the fellowship positions candidates for eligibility to sit for the American Board of Medical Genetics and Genomics (ABMGG) certification examination. Achieving board certification is a significant milestone, validating your expertise and opening doors to various career opportunities. For more detailed information, please refer to the ABMGG website.
Core Components:
The LGG fellowship encompasses a comprehensive curriculum, offering profound training in professional laboratory skills, including laboratory techniques, genomic data analysis, and the interpretation of genetic test results, along with medical genetics knowledge gained through didactic sessions. Participants actively engage in hands-on experiences across various genetic testing methodologies, ensuring they are well-prepared to navigate the evolving challenges within the field. Since it is a laboratory fellowship program, it also includes clinical lab management training. Additionally, the program typically includes non-specialty trainings such as genetic counseling, clinical genetics clinic rotations, and more.
Duration and Structure:
The LGG fellowship is typically designed as a two-year (or three-year) program, during which fellows participate in a dynamic blend of clinical lab rotations, research projects, and educational activities. This multifaceted structure aims to provide a well-rounded experience, thoroughly preparing individuals for the diverse facets of genetic laboratory practice. Laboratory training encompasses rotations in molecular genetics and cytogenetics labs, covering not only germline (or constitutional) genetic testing but also somatic (or oncology) genetic testing. The duration of each rotation varies depending on the program and each individual's background. Non-specialty rotations, including clinical genetics clinic rotations, biochem rotations, and prenatal clinic (or lab) rotations, are also typically included.
Question #3: How can I do the ABMGG LGG fellowship program?
Embarking on the ABMGG LGG Fellowship journey requires diligent preparation. Aspiring candidates should begin by researching accredited fellowship programs, crafting compelling applications, and, if selected, undergoing rigorous training in a variety of genetic testing methodologies. Successful completion opens doors to a rewarding career as a clinical lab geneticist.
The typical application cycle kicks off in August before the fellowship start year. Application requirements usually include a CV, a statement of purpose, and (at least) three recommendation letters. In some cases, a separate cover letter may be required. After submitting the application package, the program committee reviews all applicants' profiles and selects top candidates (usually 4-5 times the number of upcoming fellows). Selected candidates undergo interviews with the program director and committee members, sometimes involving two rounds.
It's crucial to note that not all programs have openings every year, and some institutions may have openings every other year. Additionally, institutions may vary in the number of openings per application cycle. Unlike the Matching system, each institution has its own application cycle, allowing candidates to apply to multiple institutions and receive multiple offers.
Lastly, each program has a unique curriculum with different strengths and weaknesses. It is highly recommended to reach out to program directors or alumni for insights into the training program. The current list of accredited LGG fellowship programs can be found on the following link. If you're interested in specific institutions/programs, contact the program director (or coordinator) to inquire about openings and application cycles.
(Make sure select "laboratory genetics and genomics" specialty)
In Summary
Clinical lab geneticists, as specialized medical professionals, play a pivotal role in performing genetic testing, interpreting results, and crafting personalized patient care strategies. To attain ABMGG board certification, individuals with a doctoral degree in genetics must complete the two-year (or three-year) ABMGG LGG fellowship program and successfully pass the board exam. Accredited by the ACGME, the LGG fellowship program offers a comprehensive curriculum covering laboratory skills, genetic testing data/result analysis, didactic medical genetics knowledge, and lab operation management training opportunities. In the absence of a centralized application system, prospective candidates are encouraged to directly contact program directors (or coordinators) for information on position openings, application cycles, and program details.
