The challenge of implementing genetic tests with clinical utility while avoiding unsound applications

Area of Science:

• Genetics and Genomics
• Translational Medicine
• Public Health

Background:

• Rapid advancements in genetics and genomics have not yet fully revolutionized medical practice.
• Translation of genetic research into public health applications is lagging.
• Direct-to-consumer (DTC) genetic testing is increasingly available for various conditions.

Purpose of the Study:

• To address concerns regarding the commercial introduction of genetic tests outside traditional healthcare.
• To highlight the paradox between slow clinical utility implementation and rapid DTC test availability.
• To discuss the need for assessing clinical validity and utility for genetic test translation.

Main Methods:

• Review of current trends in genetic testing market entry.
• Analysis of the gap between research findings and clinical application.
• Examination of established genetic associations in areas like oncogenetics and cardiogenetics.

Main Results:

• Many DTC genetic tests are introduced without sufficient evidence of clinical validity or utility.
• Implementation of genetic tests with proven clinical utility in healthcare remains slow.
• Introduction of genetic tests for complex disorders is often premature due to lack of data.

Conclusions:

• Prioritizing genetic testing in settings with proven or likely clinical utility is essential.
• Further information on diagnosis, prognosis, and disease management is needed for broader application.
• Robust monitoring and evaluation frameworks are critical for responsible integration of genetic testing.
