According to my friend who is a geneticist, 30% of cases of autism can be found in DNA. Clearly not all cases are.

- ellisv 1y agoIt's important to note our understanding is far from complete. There may be more genes associated with autism than we currently know. So 30% of cases may have a known genetic factor but that doesn't mean 70% don't have a genetic component.
- azinman2 1y agoTrue. But we’ve also seen environmental correlations as well, as well as things like age of the father, etc.
- ellisv 1y agoThis is also explained as a genetic factor as chromosomal abnormalities and replication errors are more frequent although cumulative environmental exposures may also play a role.
- sheepybloke 1y agoThat's what our genetic councilor said as well. It's important to note autism is a spectrum and quite varied, some of it genetic and some of it related to other factors.
- elcritch 1y agoI've read some studies which suggest there's a variety of genes which are linked to autism as well as link to both autism and ADHD. I believe those genes are linked to how different brain circuits interact. It makes a lot of sense given with I've seen talked a lot about in autism and adhd groups, with some symptoms overlapping.
- matt-attack 1y agoWell diagnosing autism is incredibly subjective anyway. It’s not like a broken arm.
