Pathways from autism spectrum disorder diagnosis to genetic testing

Area of Science:

• Genetics
• Developmental Pediatrics
• Medical Ethics

Background:

• Autism Spectrum Disorder (ASD) diagnosis and management involve complex considerations.
• Genetic testing is increasingly explored for identifying etiologies of ASD.
• Understanding family and provider perspectives is crucial for effective genetic testing implementation.

Purpose of the Study:

• To examine the challenges faced by families and healthcare providers regarding genetic testing for ASD.
• To identify variations in the process and decision-making surrounding ASD genetic testing.

Main Methods:

• Qualitative study involving 14 parents and 15 health providers.
• Interviews were conducted to explore experiences and perceptions of ASD genetic testing.

Main Results:

• An unstandardized three-step process for ASD genetic testing was identified: diagnosis, offer of testing, and parental decision-making.
• Significant variability exists in provider approaches, consensus, and perceived clinical utility of ASD genetic testing.
• Families often lacked awareness of genetic testing options, with decisions influenced by provider recommendations and insurance coverage.

Conclusions:

• Genetic testing for ASD requires careful consideration of clinical utility and insurance coverage variations.
• Policy makers should clarify the purpose and promote consensus on the appropriate use of genetic testing in ASD care.
