Factors that Influence Uptake of Genetic Testing for Children with Autism Spectrum Disorder: A Scoping Review

Abstract

Genetic testing is recommended for all children diagnosed with autism spectrum disorder (ASD), yet available evidence suggests that not all receive appropriate genetic testing. We conducted a scoping review of factors that influence parent/caregiver uptake of genetic testing for their children with ASD. Overall, 37 articles met inclusion criteria. Themes included widespread lack of awareness of genetic testing recommendations but also varying interest in genetic testing once aware. Potential barriers included insurance and financial concerns, logistical challenges, and the lack of belief that genetics can cause ASD. Findings highlight the need to (a) better educate parents about practical benefits of genetic testing and causes of ASD and (b) increase insurance coverage and mitigate costs to improve uptake of genetic testing.
