Is autism hereditary?

You asked a question "is autism hereditary?" so I thought a few links would help with the answer:

www.sciencedirect.com/.../S2666247722000677
The heritability of autism spectrum disorder (ASD), based on 680,000 families and five countries, is estimated to be nearly 80%

www.psycom.net/autism-genetic
A recent study, published in JAMA Psychiatry, analyzed the data among 2 million people across five countries... Results of the study showed that 80 percent of autism can be traced to inherited genes

en.wikipedia.org/.../Heritability_of_autism
The heritability of autism is the proportion of differences in expression of autism that can be explained by genetic variation; if the heritability of a condition is high, then the condition is considered to be primarily genetic. Autism has a strong genetic basis.

Research tells us that autism tends to run in families.

While it's long been accepted that Autism Spectrum Disorder is heritable, no studies have been able to offer a genetic explanation.

Consensus in the scientific community seems to clearly point to it being hereditary although the exact mechanism of its transfer is not yet understood.

I've not come across any articles yet which have such large scale, rigorous studies that imply the opposite.
