Standards and guidelines for the interpretation of sequence variants: a joint consensus recommendation of the American College of Medical Genetics and Genomics and the Association for Molecular Pathology¶
Why this mattered¶
Before this consensus recommendation, clinical genetics had sequencing capacity that was beginning to outrun shared interpretive practice. Different laboratories could evaluate the same variant with different evidence thresholds, terminology, and reporting conventions, making results hard to compare across institutions and difficult to use consistently in patient care. Richards and colleagues turned variant interpretation into a more standardized evidentiary framework: five clinical categories, defined evidence types, and weighted criteria spanning population frequency, computational prediction, segregation, functional data, de novo occurrence, allelic data, and prior reports.
The paper mattered because it helped convert genomic sequencing from a specialist craft into a scalable clinical infrastructure. After 2015, laboratories, databases, clinicians, and researchers could increasingly speak a common language when classifying variants as pathogenic, likely pathogenic, uncertain significance, likely benign, or benign. This did not eliminate judgment or uncertainty, but it made that judgment auditable, comparable, and revisable. In practice, the recommendation made it newly possible to aggregate interpretations across laboratories, identify discordance, curate variant databases more systematically, and update classifications as new evidence accumulated.
Its influence also shaped later breakthroughs in precision medicine. Large-scale resources such as ClinVar, gene- and disease-specific expert panels, population datasets such as gnomAD, and modern clinical sequencing workflows all benefited from having a shared interpretive grammar. Subsequent refinements, including disease-specific ACMG/AMP specifications and quantitative or Bayesian reinterpretations of the criteria, built on the same central shift: sequence variants were no longer treated merely as observations from a genome, but as clinical claims supported by explicit, graded evidence.
