Genes implicated in autism are germline mutations present from birth, unlike most cancers which arise from somatic mutations.

“cancer is um mostly about sematic mutations and not germal mutations meaning most of the time when a person gets cancer it is not based on genes that they were born with uh it's based on genes that were at one point normal that have since acquired mutations in their mutated State they no longer function normally the person develops cancer so this complicates my analogy because only about 5% of cancers arrive from germline mutations whereas the genes that are implicated in autism are indeed germline you're born with them”
