The requirement is to maintain formal training program sites for fellows pursuing Laboratory Genetics and Genomics and related medical genetics board certifications, with nearby institutions needed to provide required training components. The selected provider(s) must deliver clinical and laboratory genetics training covering pediatric and adult genetic disorders, newborn screening follow-up, CLIA diagnostic laboratory rotations, and virtual rotations in pharmacogenomic testing/interpretation and cancer cytogenetics. Staff must include ACGME board-certified geneticist(s) and a genetic counselor, and they must train fellows in diagnosis, management, laboratory techniques, test interpretation, and genetic counseling implications while participating in lectures, journal clubs, and case conferences. Training is based in the metropolitan Washington, D.C./DMV region, including NIH and Children’s National Hospital, with residents spending two of five pediatrics years at Children’s National and two years in an NHGRI/NIH Medical Genetics residency comprising 18 months of clinical/laboratory rotations and 6 months of genetics-focused research, plus an optional fifth year for research or subspecialty genetics. The program aims to prepare graduates for ABP and ABMGG board examinations and comprehensive genetics practice.
