ABMGG Medical Biochemical Genetics case studies

ABMGG Medical Biochemical Genetics · Put your knowledge to work in context.

Medical Biochemical Genetics is a subspecialty certification offered by the American Board of Medical Genetics and Genomics (ABMGG), an organization whose stated mission is "to serve the public and medical profession by establishing professional certification standards and promoting lifelong learning as well as excellence in medical genetics and genomics." The credential is intended for physicians who have completed genetics training and wish to demonstrate subspecialty competence in inherited metabolic disease. This independent study resource is organized around six domains: biochemical genetics; inborn errors of metabolism; metabolic laboratory testing and newborn screening; clinical management and treatment of metabolic disorders; genetic and genomic principles; and counseling, ethics, and professionalism. The ABMGG Medical Biochemical Genetics case studies are 5 cases and about 2,778 words.

A Family Requests Predictive Testing for a Child with a Metabolic Condition

Parents of a 7-year-old boy with a confirmed autosomal recessive metabolic disorder (a treatable amino acidopathy) request predictive genetic testing for their 5-year-old daughter, who is asymptomatic. They say they want to 'know now' so they can start treatment early if needed, and they are anxious because a cousin was diagnosed late with severe consequences.
