Which of the following is true about the factors that contribute to autism spectrum disorder (ASD)?
A)Researchers have been able to identify a specific gene that causes ASD, thereby disproving the notion that ASD is a result of a combination of genes.
B)Children with ASD have a higher than average rate of other genetic disorders associated with cognitive impairment, including fragile X syndrome and PKU.
C)Children with ASD are no more likely than other children to have prenatal and birth complications.
D)Neuroimaging studies have found few structural and functional deficits in the brains of individuals with ASD, thereby strengthening the role of environmental factors.

Research has identified a number of genes that contribute to the development of ASD, but there is no single gene that has been found to cause ASD on its own. Children with ASD also have a higher rate of other genetic disorders associated with cognitive impairment, including fragile X syndrome and PKU. Prenatal and birth complications have been identified as potential risk factors for ASD. Neuroimaging studies have identified a number of structural and functional deficits in the brains of individuals with ASD, suggesting a combination of genetic and environmental factors contribute to the disorder.
