66: Mainstreaming Clinical Genetic Testing: A Conceptual Framework

Mackley MP et al., Genetics in Medicine - This episode summarizes a consensus-derived framework for mainstreaming clinical genetic testing developed from a Canadian expert focus group. The framework defines terminology, maps diagnostic pathway activities, and describes four models that vary by when genetics services become involved. Key terms: Clinical genetics, Genetic testing, Mainstreaming, Service delivery, Genomic medicine.

Study Highlights:
The authors convened a consensus focus group of 35 genetics experts from 20 clinical genetics services across Canada and combined this with literature review and iterative manuscript revision. They produced consensus definitions for mainstreaming-related terms and grouped diagnostic activities into four stages. The framework defines four mainstreaming models (to-test, to-result, to-navigation, autonomous) distinguished by the point at which responsibility shifts from nongeneticist clinicians to genetics services and identifies six categories of variables that influence model suitability. The authors propose the framework to guide standardized design, reporting, and evaluation of mainstreaming efforts to optimize genetics resources and patient care.

Conclusion:
A generalizable, high-level framework describing four mainstreaming models and influencing variables can guide implementation and standardized evaluation of clinical genetic testing outside traditional genetics services to improve access and resource use.
