Objective:
To understand the rate of genetic events in patients with autism spectrum disorder (ASD) who were exposed to assisted reproduction.
Design:
Case control study using genetics data.
Setting:
Twelve collaborating data collection sites across North America as part of the Simons Simplex Collection.
Patient(S):
2,760 children with ASD, for whom 1,994 had published copy number variation data and 424 had published gene mutation status available.
Intervention(S):
None.
Main Outcome Measure(S):
Rates of autism-associated genetic events in children with ASD conceived with assisted reproduction versus those conceived naturally.
Result(S):
No statistically significant differences in copy number variations or autism-associated gene-disrupting events were found when comparing ASD patients exposed to assisted reproduction with those not exposed to assisted reproduction.
Conclusion(S):
This is the first large genetic association to concurrently examine the genotype of individuals with ASD in relation to their exposure to ART versus natural conception, and it adds reassuring evidence to the argument that ART does not increase the risk of ASD.
