ExploreAbout this exam
Molecular Genetic Pathology (MGP) is an ABPath subspecialty certification examination, offered in cooperation with the American Board of Medical Genetics and Genomics, for pathologists who want formal recognition of subspecialty expertise in molecular diagnostics. It is a one-day, computer-based exam that combines written and practical questions in each section, and every item is multiple-choice in the one-best answer format. The exam is designed to measure both a candidate's body of knowledge and problem-solving ability; individual questions may present nucleic acid-based testing scenarios, karyotypes, sequencing or array data, graphs, pedigrees, or other images. Content spans normal molecular structure and function, molecular techniques and methods, human genetic principles, laboratory quality and regulatory issues, inherited and mitochondrial disorders, neoplastic and other acquired diseases, infectious diseases, identity and histocompatibility testing, pharmacogenomics, and informatics. A codon table and amino acid abbreviations are provided for reference during the exam. Because the test is criterion-referenced, the passing score is set in advance by an expert committee and candidates are measured against that standard rather than against each other. Preparation should combine structured review of molecular biology fundamentals with hands-on familiarity with test interpretation, variant nomenclature, and laboratory quality practice, plus timed practice with data- and image-based questions.
What you'll study
About ABPath Molecular Genetic Pathology preparation
What is the format of the Molecular Genetic Pathology exam?
It is a one-day, computer-based examination made up of combined Written and Practical questions in each section. All questions are multiple-choice in the one-best answer format, and questions may include sequencing or array data, karyotypes, graphs, pedigrees, or other images.
How many questions are on the exam and how long is it?
The ABPath description lists approximately 245 questions and approximately 6 1/2 hours of total testing time. Treat both as approximate and confirm current details, including section timing, through ABPath's published daily exam schedules before your test date.
How is the passing score determined?
ABPath uses criterion-referenced tests for certification examinations. The passing or cut-off score is determined in advance by a committee of experts in the field, and your performance is compared to that cut-off rather than to other test takers. In principle, all candidates could pass or all could fail.
How many times can I retake the exam, and how long is certification valid?
The source material available here does not state a retake policy or a validity period for this certificate. Check ABPath's Booklet of Information and the Unsuccessful Candidates page for current rules rather than relying on secondhand accounts.
Is the exam scored on a curve?
No. ABPath states that it does not use norm-referenced tests for its certification examinations. Norm-referenced tests rank candidates against one another on a curve, whereas the MGP exam measures whether you have met a predetermined standard of knowledge and skill.
What resources are provided during the exam?
A codon table and a list of amino acids with their abbreviations are available for reference in the Molecular Genetic Subspecialty examination. No other reference materials are described in the source, so plan to know nomenclature, calculations, and interpretation frameworks from memory.
Which content areas should I prioritize when studying?
The subject areas are listed as roughly equal in scope, so a balanced plan works best: molecular techniques and human genetics fundamentals, laboratory quality and regulatory issues, inherited and mitochondrial disorders, neoplastic and acquired disease, infectious disease, identity and histocompatibility testing, pharmacogenomics, and informatics.
What trips candidates up most often?
The practical, data-driven items. Candidates who only memorize facts struggle when asked to interpret a pedigree, a sequencing trace, or array results under time pressure. Build fluency reading raw data and applying variant nomenclature, and practice explaining why each wrong option fails rather than just recognizing the right one.
Who should take this exam?
It is intended for physicians with pathology training who practice or intend to practice molecular genetic pathology and want subspecialty certification. The exam is offered in cooperation with the American Board of Medical Genetics and Genomics. Verify eligibility and application requirements directly with ABPath.
