A lot of people will say "no" because they mistaken think that social and biological factors can't interact with each other.
In fact for neurological disorders to differ depending on culture has already been found. Dyslexia involves a completely different part of the brain for people who are dyslexic with the chinese language compared to english because chinese uses symbols rather than letters. There is a boy mentioned in the article who was bilingual for english and japanese but only had dyslexia for english.
Now to explain the evidence that autism may involve social factors that influence how biology expresses itself and gets identified or not as a disorder and makes socialization easier or harder.
For instance, in S. Korea making eye contact is considered rude. A child who doesn't observe this unspoken (unspoken at first anyways) social rule may be more likely to be diagnosed with autism if other traits are present. Whereas a child who never makes eye contact in the United States would be more likely to be diagnosed with autism.
One person could have a biology naturally predisposing them to make eye contact all the time no matter what social cues suggest. In fact a person could be naturally predisposed to a lot of behaviors in spite of social cues but if those behaviors happen to align with what is considered socially appropriate that person will be unlikely to be diagnosed with autism. Whereas that same person with the same biological characteristics raised in a different culture would present symptoms diagnoseable as autism.
Autism does not show any 100% genetic correlations although it does show genetic correlations. I hypothesize that if researchers looked at genetic factors for autism across cultures they would find some commonalities given some genes may be more generally related to noticing social cues and because some social norms are more common than others across cultures, but they would also see differences in the genetics that contribute to autism. These studies have probably been carried out and if I'm right or wrong please point them out.
If this is true then perhaps in the future we'll be able to recognize when a child's brain would socialize better in another cultural setting and in a wealthier more cooperative world countries will be willing to provide financial aid and immigration rights for families whose children would benefit from such a move. Though it's likely this wouldn't help all cases of autism.
Though unrelated to the main point of this opinion if you have a kid with dyslexia you should teach your kid a second language if the first language is phonetic like english try a symbolic language. If it's symbolic try a phonetic language.
