Which statement is true regarding the impact of genetic factors on Autism Spectrum Disorder?

Genetic factors play a significant role in Autism Spectrum Disorder (ASD), and research supports the idea that there is a strong heritable component associated with the disorder. Studies have shown that individuals with a family history of autism are at a higher risk for developing the condition themselves. This familial aggregation suggests that genetics contribute to the susceptibility of ASD, with various genes associated with neurodevelopmental pathways being implicated.

In contrast, genetic factors are not irrelevant, nor is the condition exclusively linked to environmental influences or physical environmental exposures. While environmental factors can contribute to the risk of developing ASD, the evidence indicates that they interact with genetic predispositions rather than serving as the sole influence. Therefore, recognizing the connection between genetic factors and family history is essential in understanding the etiology of Autism Spectrum Disorder.
